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 ...

In hard-switching designs, GaN devices can suffer from higher power losses due to body diode behavior, especially with long controller dead times. CoolGaN G5 transistors address this by integrating a ...

His test circuit uses six 2N2222 transistors to protect the Arduino from excessive current. You can see six red LEDs above which are inline with the base of teach transistor.
