imrishabh18/rp2040-motor-controller
This circuit incorporates a USB-C Power Delivery (PD) interface with a CH224K controller, a WJ500V-5.08-04P motor output connector, multiple power conditioning components including capacitors, resistors, diodes, and an RP2040 microcontroller, to manage motor control, signal routing, and power management for a USB-powered stepper motor system.
