JP1

Voltage regulator bypass

This jumper is used to select the voltage source to power the main board-regulated power

bus, VCC. Place the shorting block in the 'normal' position to power the board from the on-

board 3.3V regulator. Place the shorting block in the 'bypass' position to power the board

from an externally regulated supply. This connects the unregulated power bus, VU, to the

main regulated power bus, VCC.

JP2

Servo power bus

Connect the RC hobby servo power bus to the unregulated supply bus, VU. When a

shorting block is in place on this jumper, servo power is supplied from VU on the Cerebot II.

If the jumper block is removed, the RC hobby servo power bus must be supplied with a

source connected to the screw terminal block, J10.

JP3

VU voltage sense circuit enable

When JP3 is installed, the VU voltage monitor circuit is connected to ADC0. See page 3 of

this reference manual for a description of the voltage monitor circuit.

JP4

VS voltage sense circuit enable

When JP4 is installed, the VU voltage monitor circuit is connected to ADC1. See page 3 of

this reference manual for a description of the voltage monitor circuit.

JPA -

Pmod headers

JPH

Any of the eight Pmod headers can be connected to use either regulated or unregulated

power. To use regulated power, place the jumper block over the center pin and the pin

marked VCC. To use unregulated power, place the jumper block over the center pin and the

pin marked VU.
