SMARS with NodeMcu motor shield
thingiverse
Update: 21.04.18 Minor update: The accumulator holder fits both plates. A set of holders for the NodeMcu motor shield are designed specifically for the SMARS chassis. These holders can be installed in either the low or high position within the SMARS chassis. Furthermore, the holder for the battery/accumulator can also be mounted directly on top of the NodeMcu.
