This is a single axle with a hub that mounts to our 10 inch tires. The end opposite the hub is bored to fit a 12mm shaft. It is intended to be direct driven by our IG52 motors. The hub is welded to a steel 5/8" diameter shaft.
This small synchronous switching step-down regulator takes an input voltage of up to 36 V and reduces it to 12 V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.2 A and features reverse voltage protection.
