Jon Freeman / Mbed 2 deprecated Brushless_STM3_ESC_2019_10

Dual Brushless Motor ESC, 10-62V, up to 50A per motor. Motors ganged or independent, multiple control input methods, cycle-by-cycle current limit, speed mode and torque mode control. Motors tiny to kW. Speed limit and other parameters easily set in firmware. As used in 'The Brushless Brutalist' locomotive - www.jons-workshop.com.
