ESP32 A4988 Stepper Motor Driver Board 12V 2A CNC

The A4988 stepper motor driver board is suitable for starting stepper motors in a 3D printer because the accuracy of the motor movement is important in printing. This driver is a versatile control board and the ESP32 microcontroller with dual-core processing capability, Wi-Fi And it integrates Bluetooth with A4988 stepper motor drivers, which can control stepper motors up to 12V and 2A per phase, it also has ch340c converter chip.

Install the operating system:

Marlin, Grbl or custom firmware: Install firmware compatible with your application (3D printing, CNC, etc.).

Connect the stepper motors to the A4988 drivers.

Ensure proper configuration of microstepping and current limits in drivers.

Connect a 12V power supply that can provide enough current for your motors.

If working with high currents, ensure proper cooling for the drivers.

Use the ESP32's Wi-Fi capabilities to control the board wirelessly.

Calibrate motor stages, current limits, and terminals using firmware commands.

Connect terminals to ensure accurate homing and limit detection.

Connect any additional peripherals required for your specific application.
