	Let's toss the TB6612FNG motor controller. We only need one direction of rotation, so we control the motor with an [https://www.sparkfun.com/datasheets/Components/General/RFP30N06LE.pdf RFP30N06LE] N-channel MOSFET ~~and~~ a [https://www.vishay.com/docs/88525/1n5817.pdf 1N5817] Schottky diode. The n-FET goes on the ground side of the motor, and the diode runs in parallel with the load (i.e. is connected to the motor's two pins). This eliminates five wires ~~(ten soldering points)~~.

The n-FET goes on the ground side of the motor, and the diode runs in parallel with the load (i.e. is connected to the motor's two pins). The resistor goes between the pin and the gate lead. This eliminates five wires while adding one resistor, a net reduction of nine joints.
