2026-06-02 (Tu) SubdermalDuino Schematic for REV02

The first prototype was built entirely from off-the-shelf parts, but the next REVs should be built on custom PCBs. I started with a socket for the microcontroller demo board. I would like to change to a smaller module, but that would be a later revision. I added a BNO55 inertial measurement unit (IMU) to the schematic since it is something worth adding in the future, but I doubt it will be in the first iteration. There were only 12 LEDs, since I want to make a version the same size as the power-harvesting coil. I included a couple of power terminals to connect the wireless power source.
