This is the motor-driver option kit for the Kiduino-Max! It's all simple through-hole components, and can be soldered in less than 10 minutes by someone with modest experience.
Do pay attention to the orientation of the sockets, lining-up the notch in the socket with the indicated notch on the board silkscreen. It will make it easier to later figure out the direction that the driver IC's get inserted! The switches can be installed any direction, there is no difference.
