The Exen Mini from Nerdonic is a tiny 32-bit microcontroller compatible with arduino and breadboard development. It's not just small, it's powerful too running at 48MHz clock with 256KB ROM, 32KB RAM and 8 pins filled with functionality.
Measuring just 14.9 x 14.9mm at 0.95 grams, the Exen Mini is small as well as powerful. For size comparison is a UK 5 Pence coin (Equivalent size to a US Dime).
The Exen Mini is fully compatible with breadboard development and the Arduino IDE and comes with the Arduino Zero bootloader pre-flashed.
Show your code status, an error or make it flash when each code loop is complete, the onboard programmable led can be programmed however you like.
