Sparkfun PD Stepper - NEMA 17 Stepper Driver and Controller

The PD Stepper - NEMA 17 Stepper Driver and Controller is a compact, all-in-one solution for precision projects, eliminating the need for a separate microcontroller, driver board, and bulky power supply. It harnesses USB Power Delivery (USB-PD) for up to 50W of power, allowing for a streamlined, single-cable setup.

Ideal for projects that require precise motor control, this device integrates directly onto the back of a NEMA 17 motor, simplifying the setup process. It is perfect for applications like camera sliders, automated feeders, or smart window openers, where precision and reliability are key.

One of the standout features is its wireless control capability, powered by an ESP32-S3. This provides robust processing power along with built-in Wi-Fi and Bluetooth®, enabling seamless integration with IoT platforms such as ESPHome and ESP-NOW.

The PD Stepper also boasts silent operation thanks to the Trinamic TMC2209 driver, renowned for its stealthChop™ technology. This ensures ultra-quiet performance and includes sensorless homing, which removes the need for external limit switches.

With an onboard AS5600 magnetic rotary encoder, it offers closed-loop precision, ensuring the motor maintains its position accurately without losing steps. This makes it a reliable choice for tasks requiring exact positioning.

For those looking to expand their projects, the device includes a Qwiic connector for easy, solderless integration with the extensive SparkFun Qwiic ecosystem. This allows for straightforward addition of sensors, displays, or relays.

The PD Stepper is not just functional but also robust, featuring aluminum heatsinks and a polycarbonate cover for protection. Its design ensures it fits perfectly on a standard NEMA 17 motor, making it a comprehensive and user-friendly solution for various motion control applications.
