Can the motors listed here https://www.pololu.com/product/1418 for the Zumo Chassis Kit (No Motors) be controlled using a Baby Orangutan B-328?
If you are using 4 AA batteries to power the motors, you will probably be fine. However, we generally recommend that the continuous current draw of the motor driver be greater than the stall current of the motor, and the motors listed on that page have stall currents greater than the amount of continuous current the motor driver on the baby orangutan can supply. If you want to use the Baby Orangutan, you might consider using the medium power or low power versions of the micro metal gearmotors with that chassis. Alternatively, you could also use a more powerful motor driver like our Dual MC33926 Motor Driver Carrier.
