Arduino SimpleFOC PowerShield v0.2

A powerful arduino shield for running BLDC motors using the FOC algorithm. This board is based on the BTN8982 half bridges and can support currents up to 30 Amps continuos and 50Amps peak. Making it a board that can run virtually any BLDC motor.

Features

Future features

• Stackable: running 2 motors in the same time
• I2C interface: Integrated 4.7kΩ pullups (configurable)
• Configurable pinout: Hardware configuration - soldering connections

New version of the SimpleFOC PowerShield is in the development at the moment (v0.3). The first versions are currently in testing. For more info check the developmental branch
