			=== Jumper Configuration ===
			There are a number of jumpers on Lia used to configure voltage levels and power input. Their locations and functions are identical to those on the Lisa/M v2.0. The descriptions below thus apply to both boards.

			The default configuration is UART3 VCC at V_IN, UART1/2/5 VCC at +3V3, with the V_SERVO servo voltage rail NOT connected to the autopilot V_IN rail, allowing one to power the autopilot and servos separately. The +5V regulator is NOT bypassed, allowing a regulated +5V on listed headers and for the CAN transceiver and I2C level shifter. The V_BATT connector is NOT connected to V_IN, so one can attach a battery voltage to the V_BATT pin to measure the battery voltage, if so desired.
