Scooter

E-scooter, based on the traditional human-powered skateboard, is a tool with power suite. The current e-scooters are generally two-wheel driven or single-wheel driven. The most common drive methods are HUB and belt drive. Its main source of power is from lithium battery packs.

Based on MindMotions MM32SPIN0280 microcontroller, the scooter reference scheme takes MM32SPIN0280 as its main control:

- Support dual-mode control, Hall FOC or sensorless FOC

- Support multiple systems and protection

- Support Hall self-learning and phase self-detection

- Support single resistor current sampling
