The output shaft included in this kit is a 3 mm hexagonal axle that is 10 cm (about 4") from tip to tip. The axle works with many of the Tamiya wheels Pololu carry. The low-voltage motor runs on 0.5 V to 3 V and draws less than 1 A, making it a perfect candidate for the DRV8835 or the DRV8833 motor driver carrier. The mounting holes on the gearbox are compatible with the Tamiya 70098 universal plate set and other Tamiya construction series products
