Matseng made a contest in the forum. If you guess what the PCB is, he’ll send one over.
This PCB is exactly the same size as a credit card and have the XMega, a Lipo battery and charger, a MicroUSB for comms and charging, a buttload of tactle switches and a bunch of 7-segment displays on it. I’ll tweak the design a bit more and then send the gerbers to Seeed and see if I can get it working. Major parts of the firmware is already done for the 644 so it’s about time to actually try it on some real hardware.
I’ll send a PCB for free to the first person that correctly guesses what this project actually is meant to be.
