A set of spacers and connectors together with PCBs for the expansion of the Pololu 3pi robot. Red PCB with cutouts for the display and connectors.

The expansion plate adapts to the chassis diameter of 3pi and is mounted just above the wheel tops with the four attached screws and spacers. Once assembled, the circuit board has electrical connections with the base, which allows you to connect your own electronics with a 3pi robot. These connections provide access to three voltages: VBAT (battery voltage), VCC (adjustable 5 V) and VBST (adjustable 9.25 V, which is supplied to the motors). In addition, the expansion board connects to the base's power button and battery charging port, allowing you to add your own power buttons and charging ports. The circuit board has cutouts that allow access to the LCD screen and power button, reset button and ISP programming header.

For users who need additional I/O lines or additional space for prototyping and do not need an LCD display, a better version of the expansion kit will be a board without cutouts.
