2.1.2 Power Supply

Apply 4V to the EXTIN SMA connector (P5), or supply 5V via the mini USB connector. The onboard voltage regulator provides 1.8V, 2.5V, or 3.3V to the LMK6X devices based on the jumper selection on J6. The external supply connected to P5 can also directly supply voltage to the LMK6x device by shorting pins 1 and 2 on J8.
