Arduino Shiled for running Gimbal BLDC motors with FOC algorithm

Arduino SimpleFOCShield v2.0.3

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:
  • Enable/disable by soldering pads
• Max power 120W - max current 5A, power-supply 12-24V
  • Designed for Gimbal motors with the internal resistance >10 Ωs.
• Stackable: running 2 motors in the same time
• Encoder/Hall sensors interface: Integrated 3.3kΩ pullups (configurable)
• I2C interface: Integrated 4.7kΩ pullups (configurable)
• Configurable pinout: Hardware configuration - soldering connections
• Arduino headers: Arduino UNO, Arduino MEGA, STM32 Nucleo boards...
• Open Source: Fully available fabrication files - how to make it yourself
