برد درایور استپر موتور A4988 برای راه اندازی موتورهای پله ای در پرینتر سه بعدی مناسب می باشد زیرا که دقت حرکت موتور در پرینت کردن مهم است .این درایور یک برد کنترل همه کاره است و میکروکنترلر ESP32 با قابلیت پردازش دو هسته ای، Wi-Fi و بلوتوث را با درایورهای موتور پلهای A4988 ادغام میکند که میتواند موتورهای پلهای را تا 12 ولت و 2 آمپر در هر فاز کنترل کند، همچنین دارای چیپ مبدل ch340c نیز می باشد.
Description:
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.
