User Manual

The m3pi expansion kit includes a 2×7 0.1″ female header and a 1×2 0.1″ female header that must be
soldered to the 3pi robot base to act as receptacles for the extended male headers you just soldered
to the m3pi expansion PCB:
The 2×7 female header becomes the 3pi expansion header and the 1×2 female header becomes
the 3pi power button header; the 3pi ships with the 1×2 female battery charge port header already
soldered in. These two female headers should be soldered to the 3pi robot in the locations denoted by
the red boxes in the picture below:
To connect the m3pi expansion PCB to the 3pi robot, female
headers (red) and standoffs (yellow) are required.
With these headers soldered in place, your 3pi will have the three female headers it needs to accept
the three extended male headers you soldered to the m3pi expansion board:
