Chapter 4 USB stick board description
4.1 Board overview
The USB stick board utilizes the same small footprint as Sensor Board is also a dual-layer printed circuit
board (PCB). It contains the minimalistic design of the MC13191 RF transceiver connected through an
8-bit MCHC908JW32 microcontroller to the USB. It’s main task is to receive data from the Sensor Board
and transfer it to the PC over the USB link.
