![]() ![]() ESP32 Code Example For The A4988 Driver Project In the next section, you will program the ESP32 module. You have now completed all the needed connections. Step 6: Connect the power supply ( 9 V )Ĭonnect the power supply to the A4988 driver module. Step 5: Connect the Stepper motorĬonnect the 4 pins of the stepper motor driver to the stepper motor. Step 4: Connect the STEP control pinĬonnect the GPIO14 pin of ESP32 to the STEP control input of the A4988 driver IC. Step 3: Connect the DIR lineĬonnect the GPIO12 of the ESP32 to the DIR (direction control) pin of the A4988 Module. You can connect anything between 3 V and 5.5 V. Step 2: Connect the logic supply for the A4988 driver ICĬonnect the VIN of the ESP32 to the A4988 driver IC’s supply pin. In this section, we will build a project using ESP32 and A4988 stepper motor driver IC. Let’s go! Step-By-Step Instructions To Connect The A4988 Driver Module with ESP32 ![]() The following section will connect the A4988 stepper motor driver IC to the ESP32. Overall, stepper motors are ideal for applications that require precise positioning, speed control, and low maintenance.
