    VBAT on 80-pin accessories connector on Intel Aero Compute Board


      We are intending to use the VBAT pin on the Compass and Telemetry port of the 80-pin accessories connector to power external ICs/boards with sensors.


      We measured VBAT and realised that VBAT is not equal to VIN and instead measures 0V against GND.


      How can we activate the output of VBAT to the 80-pin accessories connector? Do we need to do anything to the FPGA for it to output the VBAT?
