This is the hardware repository of a 3 phase inverter brain, UNTESTED but designed with the following specs in mind:
- Compatible with VESC firmware and software tools
- Embedded security features (overcurrent protection, pwm overlap elimination, etc)
The core of the system is a 32 bit ARM Cortex M4 MCU (STM32F405)
- CAN bus for control, configuration and monitoring
- USB for light usage, firmware upload/upgrade and configuration.
- UART, I2C and ADCs and GPIOs available
- Bus Voltage (differential)
- Phase current (differential)
- Phase voltage (differential)
- Gate driver fault
- Power_good from gate driver
- Motor temperature
- Hall/encoder
- Resolver
- PWM high/low
- dynamic gate drive current (pwm)
- 24v power
