What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy M4 Express featuring the Microchip ATSAMD51 ! Small, powerful, with a ultra fast ATSAMD51 Cortex M4 processor running at 120 MHz - this microcontroller board is perfect when you want something very compact, with a ton of horsepower and a bunch of pins. This Itsy is like a bullet train, with it's 120MHz Cortex M4 with floating point support and 512KB...

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 something very compact, but still with a bunch of pins. ItsyBitsy M0 Express is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital GPIO pins (12 of which can be analog in, 1x analog out,...

Give your ItsyBitsy project a lift with the Adafruit AirLift Bitsy Add-On - a daughterboard that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite ItsyBitsy (like the Itsy' M4) that comes with its own set of awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi...

If you have an ItsyBitsy or Pro Trinket you probably know it's the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 boards together to make a charging system, this little PCB sits on top of the PCB and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket or ItsyBitsy USB port is powered, the battery is recharged automatically. Unplug the USB port and the...

These three Stacking Headers  alone are, well, lonely. But pair them with our ItsyBitsy boards, and you're in business! Great for putting something a-top your ItsyBitsy, like this AirLift bitsy add-on. Also works great for 'short' Teensy boards - not Teensy 3.5 or 3.6 long style boards. Note:  Kit includes two 14-pin and one 5-pin header.  ItsyBitsy not included.  Don't need all that stack?...

These three Short   Female Headers  alone are, well, lonely. But pair them with any of our ItsyBitsy boards, and you're in business! These headers are particularly cute and tiny with a body height of just 5.0 mm they are the best way to minimize the amount of space your ItsyBitsy project takes up, but still maintain that flexible configuration. "Normal" socket headers have an 8.5mm body height so this saves...

These three  Short   Male Headers  alone are, well, lonely. But pair them with our ItsyBitsy boards, and you're in business! These headers are particularly cute and tiny and are designed to match perfectly with our shorty female header kit for ItsyBitsy. Note that you could use normal header with those headers, but these are short and don't need clipping.  Note: Kit includes two 14-pin and one 5-pin header....

You've heard about CircuitPython and maybe you want to get started fast with a breadboard-friendly microcontroller board! We recommend the ItsyBitsy M4 - a super fast chip with tons of GPIO, analog inputs & outputs, with so much RAM that you'll never have to worry about running out of memory. And what better way to get acquainted with ItsyBitsy M4 than with this handy  CircuitPython Starter Kit ?  Small, powerful, with a...

What's smaller than a Feather but larger than a Trinket? It's an ItsyBitsy! Small, powerful, Arduino-compatible - this microcontroller board is perfect when you want something very compact, but still with a bunch of pins. ItsyBitsy is only 1.4" long by 0.7" wide, but has 6 power pins, 6 analog & digital pins and 17 digital pins. It packs much of the same capability as an Arduino UNO. So it's great once you've...
