Arduino SimpleFOCShield v2.0.4
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.
Features
- Plug & play: In combination with Arduino SimpleFOClibrary - github
- Low-cost: Price of 15-20€ - Check the pricing
- In-line current sensing: Up to 3Amps/5Amps bidirectional
- configurable: 3.3Amps - 3.3V adc, 5Amps - 5V adc
- Integrated 8V regulator:
