SimpleFOC Drive

# *Simple**FOC*** ***Drive**Shield* *v1.2* This is an open-source low-cost BLDC driver boards in the form of a Arduino shield. It is a part of the *Simple**FOC*** project. The board is the big brother of the *Simple**FOC**Shield* and is designed to drive motors with higher current requirements, up to 30Amps. The board is created with the same philosophy as the *Simple**FOC**Shield* - to be simple to use, low-cost, and open-source and fully compatible with the *Simple**FOC***library. Additionally the aim of the board is to serve as a template project for the community to build their own motor drivers. - The board is relatively simple and can be easily modified to fit different requirements. - The board is designed in EasyEDA and all the fabrication files are available for download ### Features - **Plug & play**: In combination with Arduino *Simple**FOC**library* - [github](https://github.com/simplefoc/Arduino-FOC) - **In-line current sensing**: Up to 5Amps bidirectional - ACS712 hall current sensor - **Absolute max ratings** - Designed for Gimbal motors with the internal resistance >10 Ωs. - Max current: 30A, - 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/SimpleFOC-Drive) - Fully available fabrication files - [how to make it yourself](https://docs.simplefoc.com/arduino_simplefoc_shield_fabrication) - **Low-cost**: Estimated price of 25-40€ - *Will be available in the SimpleFOC shop* ## Board evolution timeline To check the release timeline, click [here](https://github.com/simplefoc/SimpleFOC-driveShield/releases) Version | release | Release date | Comment ----- | ----- | ---- | ---- *Simple**FOC** **Drive**Shield* v1.0 | v0.1 | 05/24 | - Test version
