This RP2040 wristwatch has circular PCB which works as the face. An of course it’s surrounded a string of RGB LEDs to light up the circumference.
Makers never cease to amaze us when it comes to the cool Raspberry Pi-powered wearables they create. Today we’ve got an awesome wristwatch PCB created by maker and developer Kim Paulsson that features a Raspberry Pi RP2040 microprocessor as used in the Raspberry Pi Pico. Instead of using hands to point to the hour and minute, Paulsson is using a ring of RGB LEDs.
