42 Stepper Motor Driver Expansion Board for A4988 DRV8825

The 42 Stepper Motor Driver Expansion Board is a highly convenient breakout module designed to simplify NEMA 17 (42mm) stepper motor control in your DIY 3D printers, CNC machines, and robotics projects. This board acts as a carrier for popular step/direction stepper driver modules like the A4988, DRV8825, or pin-compatible TMC series drivers. It eliminates the need for complex breadboard wiring by breaking out all essential control pins, power inputs, and motor outputs into robust, easy-to-use connectors.

Equipped with an onboard 3-way DIP switch, this expansion board allows you to easily configure the microstepping resolution (MS1, MS2, MS3) of your driver module on the fly. It features a dedicated 2-pin screw terminal for motor power input (VIN/GND) and a standard 4-pin JST-XH connector for direct plug-and-play connection to NEMA 17 stepper motors. This makes it an excellent choice for interfacing stepper motors with microcontrollers like Arduino, ESP32, or Raspberry Pi in automated systems.

Features:

• Multi-Driver Compatibility: Seamlessly supports A4988, DRV8825, and pin-compatible TMC series stepper driver modules.
• Onboard DIP Switches: Features MS1, MS2, and MS3 switches for quick and easy microstepping configuration.
• Secure Power Terminals: Includes a heavy-duty 2-pin screw terminal block for stable motor power input.
• Plug-and-Play Motor Port: Equipped with a 4-pin JST-XH connector matching standard NEMA 17 stepper motor cables.
• Easy Microcontroller Interface: Standard 2.54mm pitch male headers for Enable, Direction, Step, VCC, and GND control signals.
• Robust Prototyping: Built-in filter capacitor stabilizes power delivery to protect your driver and motor from voltage spikes.
