Mike Tooley's book will show you how the micro:bit can be used in a wide range of applications from simpe domestic gadgets to more complex control systems such as those used for lighting, central heating and security applications. Using Microsoft Code Blocks, the book provide...

The micro:bit, a tiny computer being distributed by the BBC to students all over the UK, is now available for anyone to purchase and play with. Its small size and low power requirements make it an ideal project platform for hobbyists and makers. You don't have to be limited by...

Trinket's got a big sister in town - the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in.

LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are...

The SparkFun micro:bit Breakout is a board that connects to the BBC micro:bit and expands the capabilities of the development platform by providing access to more pins and allowing for connections to the I2C and SPI buses. This breakout board for the micro:bit’s edge connector...

This low-cost (LC) Teensy Prop Shield is meant for making light and sound effects on small, handheld props and wearable costumes. This shield features a 2W audio amp, high-speed 5V buffers for driving APA102 LEDs, and an 8MB flash memory. This economical board is approximately...

The Arduino Leonardo is a microcontroller board based on the ATmega32u4. It is the latest addition to the Arduino family.This chip has about the same amount of flash, RAM and capability as the ATmega328 found in the UNO.

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.

Wireless charging uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

WRTnode2P Devboard is a minimal standard interface module, delightful price, comprehensive software support, a wealth of documents and communities, good looking, texture, to I.o.T new era.

Sometimes we wonder if robotics engineers ever watch movies. If they did, they'd know that making robots into slaves always ends up in a robot rebellion. Why even go down that path? Here at Adafruit, we believe in making robots our friends!

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 a wonderful combo, 2.4GHz Mini Wireless QWERTY keyboard mouse, TouchPad combo, with USB interface adapter for Raspberry Pi, Cubieboard, Mini PC and others. The Ergonomically handheld design is easy to carry and operate. Build-in removable rechargable Li-ion battery tha...

The Power Dock 2 allows you to use any 3.7V LiPo battery to power your Omega and then charge the battery when it’s out of juice. Utilizing the same form factor as the Expansion Dock, this board also can be used in the same way, so if you don’t have a battery connected you will...
