Raspberry Pico BLDC controller

BLDC controller based the DRV8320 controller in 1X PWM mode.

It supports:

• Resistive braking (external brake resistor)
• Regerative braking
• MOSFET braking
• 2x external loads (lights etc, up to 20A)
• MicroPython
• Wireless communication with the nrf24L01+ module

A great learning platform.

Progress:

1. (done) Design schematic
2. (done) Design PCB
3. (done) Solder and test PCB
4. (done)Measure battery voltage
5. (done) Read the hall-sensors and measure RPM
6. done) Read the temperature sensor
7. done) Drive a motor
8. Wireless communication
9. Drive a second PCB with a single Pi Pico
10. Use PIO instead of SPI0

TODO in rev2:

• Add rev nr
• Fix nrf pinout
• Add bulk cap close to nrf module
• Change R45 value from 100k to 10k
