Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little ...

Launched on IndieGogo a few months ago after 2+ years in development, Crowbits is a STEM education project that leverages both the Arduino and ESP32 boards to teach logical thinking and programming.

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor..
