# Arduino *Simple**FOC**Shield* *v3.2*
  
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 *Simple**FOC**Shield*, in combination with the *Simple**FOC**library* provides user-friendly way to control BLDC motors both in hardware and software.
### Features
- **Plug & play**: In combination with Arduino *Simple**FOC**library* - [github](https://github.com/simplefoc/Arduino-FOC)
- **Low-cost**: Price of 15-30€ - [Check the pricing](https://www.simplefoc.com/shop)
- **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 in **EasyEDA**: [EasyEDA project](https://oshwlab.com/the.skuric/simplefocshield_copy_copy) 🎉
- Fully available fabrication files - [how to make it yourself](https://docs.simplefoc.com/arduino_simplefoc_shield_fabrication)
### New Features v3.x
- Transition away from stm's L6234 chip to [DRV8313](https://www.ti.com/lit/ds/symlink/drv8313.pdf?ts=1719079575798), which is much more available
- Transition form TI's INA240 current amps to Allegro's [ACS712](https://www.sparkfun.com/datasheets/BreakoutBoards/0712.pdf) 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](https://oshwlab.com/the.skuric/simplefocshield_copy_copy)**
