Tomu
PRODUCT ID: 4050
Only 13mm long, Tomu really puts the micro in microprocessor. It's fully opensource development board with the silabs Gecko EFM32HG309 processor, on a
little board that can slot right into your computer or laptop USB A port (USB C
users will need an adapter).
The board feature two tiny LEDs, and two capacitive-touch pads, as well as a
native USB bootloader. While it was originally designed for 2-factor
authentication, it's great for very tiny USB projects, ARM/Gecko experimentation
or adding a basic input to your computer. Best of all, it's fully open
source! Check out the GitHub repo with lots of examples, programming
instructions and projects
