PD Stepper - USB PD Closed Loop Stepper Driver & Controller

PD Stepper is a USB PD Powered Nema 17 stepper driver using the Silent Trinamic Driver TMC2209 controlled with a ESP32-S3 for IoT and other applications.

Stepper motors are fantastic for projects, but assembling the necessary components—like a microcontroller, stepper driver, power supplies for both motor and microcontroller, and optionally an encoder can lead to bulkiness, high costs, complexity, and challenges in integrating them into compact or space-constrained designs. The PD Stepper addresses these issues by consolidating everything onto a single board, eliminating the drawbacks with little to no compromises.

Main Features:

TMC2209 Stepper Motor Driver: Incorporates the TMC2209 stepper motor driver, renowned for its silent operation, high precision, and advanced features such as stealthChop™, spreadCycle™ and sensorless homing, ensuring smooth, silent and efficient motor control.
USB PD Power: Utilizes the USB PD standard for power delivery, giving high power, a USB-C connector and no bulky 12 and 24V power bricks needed. USB PD along with the TMC2209 can drive a stepper motor with up to ~50W of power.
Form Factor: Super compact forma factor, designed to fit on the back of a common Nema 17 stepper motor
Onboard Rotary Position Sensor: Integrates the AS5600 magnetic rotary position sensor for accurate and reliable absolute angle measurement, enabling precise positioning and closed loop control of the stepper motor.
ESP32-S3 Control: The ESP32-S3 microcontroller serves as the brains of the system, providing ample processing power, built-in Wi-Fi and Bluetooth connectivity. As well as a rich ecosystem of development tools and libraries for easy customization and expansion such as ESPHome and ESPNow.
Auxiliary connectors and buttons for flexibility and expansion
Onboard 3.3V buck converter
Input for motor temperature measurement
