Build process documentation
Specification
Nodes are supposed to be equipped with:
- RF transceiver
- 4 buttons, labelled with digits, letters, colours (probably red / blue / green / yelow) and symbols (playstation style?)
- a LED for each button in matching colour
- an RGB LED
- a buzzer
- a 1-wire interface for authentication buttons (iButton)
For ease of development, they also get a serial interface ("FTDI cable" -- power supply + RX/TX + reset, also for flashing using a boot loader).
