This is an open-source low-cost Brushless DC (BLDC) motor driver board intended primarily for low-power FOC applications up to 5Amps. The board is fully compatible with the Arduino UNO and all the boards with the standard Arduino headers. The SimpleFOCShield, in combination with the SimpleFOClibrary provides user-friendly way to control BLDC motors both in hardware and software.
- Plug & play: In combination with Arduino SimpleFOClibrary - github
- Low-cost: Price of €15 - Check the pricing
- In-line current sensing: Up to 3Amps/5Amps bidirectional
- configurable: 3.3Amps - 3.3V adc, 5Amps - 5V adc
- Integrated 8V regulator:

This is a project of designing and controlling the reaction wheel inverted pendulum based entirely on Arduino SimpleFOClibrary and SimpleFOCShield
This is a very fun project in many ways, and it is intended:
- Students in search for a good testing platform for their advanced algorithms
- Everyone with a bit of free time and a motivation to create something cool :D
For full documentation of necessary components, design choices and the code please visit the project docs.
This video demonstrates SimpleFOCShield support for stacking with Arudino UNO and STM32 Nucleo-64 board. As well as support for different sensors magnetic and encoders with relatively large precision span.
The control algorithms implemented in this project are :
- Steer by wire (force feedback): two motors with virtually coupled positions
- Interactive gauge (haptic velocity control): two motors with virtually coupled position and velocity
For full documentation of the projects setup and the code please visit the project docs.
