This pin is an input to the digital brick controlled by the M1AFS1500-FG484 I/O with a PWM control. The PWM
output can be configured using different RC values on the surface mount pads
This pin can be used to trim the output voltage of the digital brick. The trim voltage varies based on the type of digital
brick being used.
Battery operation of the System Management Board includes battery backup, charging, and discharging routines using
the M1AFS1500-FG484 device.
A maximum 7.2 V NiMH 2100 mAh battery can be plugged in the two pin header JP4. The battery operates for
approximately 15 to 20 minutes. Make sure the polarity of the battery matches the silkscreen on the header. A
temperature diode can be plugged in the two pin header JP5 and can be placed on the battery to monitor temperature,
