Appendix B
Motor-Power Board Connectors
The Pioneer 2 has a separate Motor-Power Board which, in conjunction with the microcontroller, provides
power for the two and four motors of the Pioneer 2 DX, CE and the Pioneer 2 AT models, respectively, as
well as conditioned power for the standard and accessory onboard electronics (Figure B-1). It also contains
buffered pass-through connectors for the motor encoders. An optional power package ("computer ready") is
available for an onboard computer system and Ethernet radio.
Find the Motor-Power Board attached to the back of the battery box.

User Power Connections
On the Pioneer 2 Motor-Power board, four sets of un-switched battery (Vpp) and DC-DC-conditioned
five volts (Vcc) power, with power ground (Gnd), are available for accessory and custom electronics on a
12-pin Molex-type latch-lock (100mm) connector (Table B-1). The Vcc power gets shared with the micro-
controller and accessories connected to that board (Appendix A). The maximum Vcc power available with
standard DX, CE and AT models is 1.5A; 3A with computer-ready option.
