PicoPlanet is a procedurally generated series of PCBs. The three planets act as capacitive touch buttons. The board also has a RGB LED on top, a USB-C connector and 4 more pin pads on the bottom. The board's brain is a powerful SAMD21. The design also has stars that are not covered by copper or soldermask and are perfect spots to place more LEDs.
PicoPlanet is compatible with Arduino and Circuit Python. For usage see the documentation link.
PicoPlanet boards can be used as small additional Keyboards. Control your PC Media, OBS, your room light or anything else you'd like. Use the RGB LED as little status notification. Maybe add a small vibration motor for haptic feedback or built a nice case utilizing the M2 mounting holes. Reach for the stars!
