Step 2. Wire the IOIO to the Motor Controller

We need to make three power connections between the IOIO board and the motor controller (Figure 5-7). Break off a length of 7 header pins and fit it into the sockets on the motor shield and two lengths of two pins. Fit the first of these into the 3.3V and Vin sockets on the IOIO, and the other into two of the GND connections on the IOIO. We are going to solder the leads between these headers.

Solder the first wire between VM (motor voltage) on the motor controller and Vin on the IOIO. The second wire is between Vcc on the motor controller and 3.3V on the IOIO, and the final connection is between the GND pin on the motor controller and one of the GND connections.
