3. Two PCBs, 3 μ C: - One rotating PCB to drive LEDs - One stationary PCB for location detection, interfacing with user μC #1 handles the UI, RF beacon location detection, and pixel maps μC #2 stores data from the transceiver in a buffer μC #3 shifts the data out of the buffer to the LEDs and handles timing
