What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy M0 Express! Small, powerful, with a rockin' ATSAMD21 Cortex M0 processor running at 48 MHz - this microcontroller board is perfect when you want...

Your power supply problems just got SOLVED! This little circuit board may look tiny but inside is a high efficiency DC/DC step-down converter which can output up to 3 Amp at 5V without the need of any heat-sink or forced cooling. (It...

The first time you soldered up a surface mount component you may have been surprised "these are really small parts!" and there's a dozen of different names too! QFN, TDFN, SOIC, SOP, J-Lead, what do they mean and how can you tell how big...

This little remote control would be handy for controlling a robot or other project from across the room. It has 21 buttons and a layout we thought was handy: directional buttons and number entry buttons. The remote uses the NEC encoding...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller. To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen...

With our fun assortment of conductive materials , cosplay and wearables have never been easier to craft! This Conductive Nylon tape goes great with our other interesting materials, such as copper tape, ITO glass or plastic, conductive...

Did you really think the Raspberry Pi would stop getting better? At this point, we sound like a broken record, extolling on the new Pi’s myriad improvements like we’re surprised that the folks at the Raspberry Pi foundation are...

The 6DOF IMU 11 click is a Click board™ based on the KMX63, a 6 Degrees-of-Freedom inertial sensor system on a single, silicon chip, which is designed to strike a balance between current consumption and noise performance with excellent...
