Tiny Arduino Leonardo Compatible Board
Are you looking for a tiny Arduino-compatible board? Then check out this beetle board from PMD Way. It houses the ATmega32U4 - identical to the Arduino Leonardo - in an incredibly tiny 21x28mm PCB.
And as you can see, the PCB has a USB plug on one corner, allowing for easy code uploading - or leaving it plugged into a PC.
This is a neat board which along with the usual microcontroller-based projects, can be used as a keyboard or mouse emulator. Ideal for personal password devices, keeping PCs awake - or practical jokes!
Inline header pins are included, but not soldered to the board.
