The IC devices on the radio board require many different voltages. The daughtercard interface provides 5VDC; all other voltages are derived from this source. The image above illustrates the test points provided on the board for measuring the output of each voltage regulator. Most of these regulators also have red LEDs at their outputs which will glow whenever the board has power.
