Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.This is the Adafruit Feather HUZZAH ESP8266 - our take on an 'all-in-one' ESP8266 WiFi development board with built in USB and battery charging. Its an ESP8266 WiFi module with all the extras you need, ready to rock! We have other boards in the Feather family, check'em out here. At the Feather HUZZAH's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. We wired up a high-quality SiLabs CP2104 USB-Serial chip that can upload code at a blistering 921600 baud for fast development time. It also has auto-reset so no noodling with pins and reset button pressings. The CP2104 has better driver support than the CH340 and can do very high speeds without stability issues.To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. Here's some handy specs!

PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-sharing battery charger circuit, you'll be able to keep your power-hungry project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. If you dont need the 1A battery charger, smart load-sharing, or 1A iOS resistors, check out the Powerboost 500C Like our popular 5V 1A USB wall adapter , we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' for long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance.The PowerBoost 1000C has at the heart a TPS61090 boost converter from TI . This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs!Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output2A internal switch (~2.5A peak limiting) means you can get 1000mA+ from a 3.7V LiPoly/LiIon battery. Just make sure your battery can handle it!Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo/LiIon battery usageOnboard 1000mA charge-rate 'iOS' data resistors. Solder in the USB connector and you can plug in any iPad, iPhone or iPod for 1000mA charge rate.Full breakout for battery in, control pins and power out90%+ operating efficiency in most cases (see datasheet for ef
Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and SPI!This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.Nice sensor right? So we made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry. We even wrote up a nice tutorial with wiring diagrams, schematics, libraries and examples to get you running in 10 minutes!
When we were putting together the TV-B-Gone kit, we started imagining a dystopian future, filled with televisions, where this kit would be super useful and we'd be a hero for having one. And while maybe that's dramatic, the TV-B-Gone is perfect for playing pranks on your friends during the Super Bowl or getting some peace and quiet during dinner.The TV-B-Gone is a kit that, when soldered together, allows you to turn off almost any television within 150 feet or more. It works on over 230 total power codes - 115 American/Asian and another 115 European codes. You can select which zone you want during kit assembly.This is an unassembled kit which means that soldering is required - but it’s very easy and a great introduction to soldering in general. The kit’s powered by 2x AA batteries - that aren’t included - and the output comes from 2x narrow beam IR LEDs and 2x wide-beam IR LEDs. The TV-B-Gone covers almost any television from the brands listed below, including the latest flat-screens and plasma TVs. There’s also lots more info on the TV-B-Gone website.

You thought it couldn't get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, it's 1.875 times as many but that's within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticeable strip color - this strip has black-colored flex PCB, which will be less visible against black-painted walls. This is the strip with black flex PCB, it's identical to the white 60 LED/meter except it has a different color mask on the flex strip.All your dreams answered, yet there are a few things to watch for.First up, the higher density means much higher power usage over a certain distance - 18 Watts max (~3.5 Amps @ 5V) per meter instead of 9.6 Watts max (~2 Amps @ 5V). The max rating is assuming all the LEDs are on full white, usually the actual current for colorful design is about 1/3 to 1/2 the max current. A good power supply such as our 5V 10A supply is key!Second, to get high density, the controller chip is inside the LED, which is kind of cool, but also means that the chip only uses a single pin for input and a single pin for output. The protocol used is very very timing-specific and can only be controlled by microcontrollers with highly repeatable 100nS timing precision. We have example code for using with the Arduino Uno/Mega microcontroller at 8MHz and 16MHz, and with a little effort you can use with the Raspberry Pi , or Beagle Bone Black , but it will not work with the Basic Stamp, NETduino, any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz. For those processors, check our DotStar digital LED strip which has SPI-like input/output and works easily with Pi, NETduino, and other processors.Third, just because you have all those pixels doesn't mean
Mit diesem kleinen Thermodrucker ist es jetzt möglich jedes Mikrocontroller-Projekt um einen Drucker zu erweitern. Thermodrucker sind auch bekannt als Belegdrucker, sie drucken an fast jeder Supermarkt-Kasse, die Technologie kommt auch in Kontoauszugsdruckern zum Einsatz.
Mit diesem Produkt lässt sich ein kleiner Drucker in ihr eigenes Projekt integrieren. Der Drucker ist ideal für die Verbindung mit einem Mikrocontroller. Alles was du brauchst um Text, Barcodes, Bitmap-Grafiken oder sogar QR-Codes zu drucken, ist ein serieller 3.3V-5V TTL Ausgang von deinem Mikrocontroller.

You want to make a cool Arduino robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that the Arduino has only a few PWM outputs, and maybe those outputs are conflicting with another shield! What now? You could give up OR you could just get our handy PWM and Servo driver shield. It's just like our popular PWM/Servo Breakout but now Arduino-ready and works with any Arduino that uses shields: Uno, Leo, Mega, ADK, its all good.Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface ( 5:58 )
Im Lieferumfang finden Sie folgende Artikel: 1x Adafruit MotorShield v2.3 (Bausatz) - Arduino-Shield für Motoren, Schrittmotoren und Servos 1x Jumper 1x Stiftleiste, 36 Pins Die Stiftleiste muss noch unterteilt und an den dafür vorgesehen Stellen angelötet werden. Hinweis: Bitte beachten Sie das es sich bei diesem Produkt um einen Bausatz handelt und zur Inbetriebnahme Lötarbeiten erforderlich sind. Beschreibung von Adafruit (englisch): The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements: Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! What on earth could you do with that many steppers? I have no idea but if you come up with something send us a photo because that would be a pretty glorious project. Lots of other little improvements such as a polarity protection FET on the power pins and a bit of prototyping area. And the shield is assembled and tested here
Lithium ion polymer (also known as 'LiPO' or 'lipoly') batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2500mAh for total power of about 10 WH. The batteries come pre-attached with a genuine 2-pin jst-ph connector as shown and include the necessary protection circuitry. Because they have a genuine jst connector, not a knock-off, the cable won't snag or get stuck in a matching jst jack, and they click in and out smoothly. The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is very important that you only use a liion/lipoly constant-voltage/constant-current charger to recharge them and at a rate of 1200MA or less. Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less - 1200MA max in this case. Even 500MA is a good charge rate, which is how much you can get from a USB port.
Is this not the cutest, little display for the Raspberry Pi? It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay just like our popular original , but this one is engineered specifically to work with the newer "2x20 connector" Raspberry Pi's. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! This PiTFT 3.5" is designed to fit nicely onto the Raspberry Pi Zero, Pi 3, Pi 2 or Model A+ / B+ (any Pi with a 2x20 connector) . Not for use with an old Pi 1 with 2x13 connector If you'd like to use a 3.5" display with the original Pi A or Pi B, check out this version The display uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. GPIO #18 can be used to PWM dim the backlight if you like. All other GPIO are unused. There's a 2x13 'classic Pi' connection GPIO header on the bottom, you can connect a 26-pin Pi GPIO cable to it to use any of the other pins as you like. The other GPIO are broken out into solder pads at the bottom, in case you want to use more of the GPIO.Best of all, it comes fully assembled and ready to plug into your Pi! You can use this as a display for running the X interface, or pygame. You can also have an HDMI display seperately connected. There's four mounting ears that can be used to attach the display & Pi to a bezel, or snap them off with pliers (they're perforated) for a slick exactly-the-same-size-as-a-Pi look. We've created a custom kernel package based of off Notro's awesome framebuffer work, so you can install it over your existing Raspbian (or derivative) images in just a few commands. Our tutorial shows you how to install the software, as well as calibrate the touchscreen, display images such as from your PiCam and more! Display current draw is mostly based on the backlight, with

Beschreibung von Adafruit (englisch):
Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control.
Raspberry Pi and motors are not included.
Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.
In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.
Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel and 3A peak current capability, a big improvement over L293D drivers and there are built-in flyback diodes as well.
Dieses TFT-Display ist groß (3.5" Diagonale), hell (6 weiße LED-Backlights) und bunt! Mit einer Auflösung von 480x320 Pixeln hat das Display eine doppelt so hohe Auflösung wie sein Vorgänger (2.8", 320x240 Pixel). Als Bonus verfügt das Display über eine resistive Touchfunktion.
Dieses Display verfügt über einen eingebauten Controller mit RAM-Buffer, dieser sorgt dafür das der Microcontroller wenig belastet wird. Es verfügt über zwei Betriebsmodi: 8bit und SPI. Im 8bit-Modus werden 8 digitale Datenleitungen und 4-5 digitale Steuerleitungen benötigt um das Display zu steuern. Im SPI-Modus werden nur 5 Pins insgesamt benötigt (SPI Data In, Data Out, Clock, Select, D/C). Der SPI-Modus hat den Nachteil, das er langsamer ist als der 8bit-Modus. Zusätzlich werden 4 Pins für den Touchscreen benötigt (2 digitale und 2 analoge), optional lässt sich der Touchscreen über einen Controller (nicht beiliegend) betreiben.
Ein detailiertes Tutorial findet sich im Adafruit Learning Center. Für 8-bit-Interface-Fans gibt es eine Grafik-Bibliothek, mit der sich Pixel, Linien, Rechteke, Text und mehr zeichnen lassen. Für SPI-Nutzer gibt es auch eine Bibliothek.
