M5Stack RF UNIT 433MHz Transmitter - SYN115 Mornsun LMF600-20B48 AC/DC 600W Enclosed Switching Power Supply LED indicators on the pen

LED indicators on the pen show charging status

and macOS with freely available Prolific drivers

This combination allows implementation of complementary filtering and more sophisticated control algorithms that respond to dynamic balance perturbations much faster than accelerometer-only systems

and the neutral wire requirement ensures safe operation with proper ground reference for the control circuitry

M3 screws for attaching the motor to the bracket are included
