This repo is just for me to write down all the things I learn about the Spirit. I try to get as much info here as possible.
The Spirit consists of two boards. The first Board contains an ATMEL ATmega329PA (datasheet). This board is also connected to the motor. I call this board the temp control board.
The second board contains an Silicon Labs ZM5202 (datasheet) module with a Silicon Labs SD3502 (datasheet) chip.
