Labeling

All parts are outlined in the board, as well as the different supply and GND signals. Two LEDs indicate

the power status of the 3.3 V supply (digital, analog, and RF sections) and the 12 V supply (for the OLED

and the audio amplifier).

The figures in this chapter and Table 3-1 show the labeling of the supplies and the signals to which they

correspond:
