To use one of the onboard voltage regulators, apply between 3.6V and 5V to the EXTIN SMA connector (J13), or supply 5V using the mini USB connector. The voltage regulator provides 1.8V, 2.5V, or 3.3V to the CDC6C devices based on the jumper selection on J10 or J12.

To bypass the onboard voltage regulators and use an external supply directly, remove the jumper from J6 and short pins 5-6 on J11.
