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. TheSimpleFOCShield, in combination with theSimpleFOClibrary provides user-friendly way to control BLDC motors both in hardware and software.

• Plug & play: In combination with ArduinoSimpleFOClibrary -github
• Low-cost: Price of 15-30€ -Check the pricing
• In-line current sensing: Up to 5Amps bidirectional
  • ACS712 hall current sensor
• Integrated 8V regulator:
  • Enable/disable by soldering pads
• Absolute max ratings - Designed for Gimbal motors with the internal resistance >10 Ωs.
  • Max current: 3A,
  • Max input voltage: 35V
• 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 designed inEasyEDA:EasyEDA project 🎉
  • Fully available fabrication files -how to make it yourself

• Transition away from stm's L6234 chip toDRV8313, which is much more available
• Transition form TI's INA240 current amps to Allegro'sACS712 hall sensors
• Smaller footprint: 56mm x 53mm
• Fault and reset pins exposed (optional)
• Fault led indication
• Designed completely in EasyEDA, which is a free online PCB design tool -Official Easy EDA project
