Standard

1.Easy to use and quick to get started

2.The process supports design scales of 300 devices or 1000 pads

3.Supports simple circuit simulation

4.For students, teachers, creators

Profession

1.Brand new interactions and interfaces

2.Smooth support for design sizes of over 30,000 devices or 100,000 pads

3.More rigorous design constraints, more standardized processes

4.For enterprises, more professional users

Description

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
