Jumpers
Regulator Disable (
The Regulator disable jumper is used to allow either the CAN transceiver or the A
disable signal to the voltage regulator that powers the boards.

Current Measurement (
The current measurement jumpers are used to measure the current draw of the
VDD_EXT and USB0_VBUS
draw, remove the jumper and measure the voltage across the precision resistor. The current can be calculated by
dividing the measured voltage by the 0.051 ohm resistor. For best results a differential probe should be used to meas-
ure the voltage across the resistor.
HADC ( )
P25
The HADC jumper is used to connect the HADC of the processor to various voltages on the board for monitoring.
