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).
