Excellent STM32 alternative

Much faster than standard Arduino Uno. Compiles and uploads without issues.

Good board, minor issues

Works well but need external power for servos. Do not power high torque servos via USB.

Perfect for my robot arm

The PWM signal is very stable and controls my servos smoothly. Great value for an STM32 board.
