4.2.2 Power Supply

Set the jumpers according to the table below.

Table 4-1 Power Supply Jumper Configuration
Input Source Voltage Regulator Pins to Short on J7 Pins to Short on J8
5V USB LDO 3-4 1-2
EXTIN LDO 1-2 1-2
Bypass open 3-4

To use the onboard voltage regulators, apply between 3.6V and 5V to the EXTIN SMA connector (P5), or supply 5V using the mini USB connector. The voltage regulator provides 2.5V or 3.3V to the LMK6B device based on the jumper selection of J10.

To bypass the onboard voltage regulators and use an external supply directly, remove the jumper from J7 and short pins 3-4 on J8.
