The RoboClaw Solo 300A is BasicMicro’s highest-current single channel motor controller, rated for 300 amps continuous and 400 amps peak at up to 60VDC. It is built for high-power applications such as combat robotics, and supports USB, serial, RC, and analog control with Motion Studio configuration.

The RoboClaw Solo 300A is the newest single channel design in the BasicMicro motor controller lineup, created for high power motor control applications such as combat robotics. It is rated for 300 amps of continuous DC current with a peak rating of 400 amps, and is available in a 60VDC version. The onboard BEC for powering external hardware is rated for 1.2 amps — enough to power most microcontrollers and single board computers.

New in the Solo 300A is an expanded pin header similar to the one featured on the dual channel RoboClaw models. The expanded header supports additional limit and home switches as well as an encoder channel, and the pins are standard 3-pin headers compatible with common servo connectors. The Solo 300A carries the full complement of RoboClaw communication protocols, and our free configuration software, Basicmicro Motion Studio, is used to customize its operation.
