Pinch Fingertip-Sized 32-Bit Arduino-Compatible: The pinch crams a 32-bit Arduino-compatible board onto something the size of a USB-C plug: 15 GPIO pins, native USB, and a $16 pre-order.

Canada-based Moddo has designed the Pinch board, which it claims is the world's smallest 32-bit Arduino-compatible board so far, measuring just 10.9 x

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really…
