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
