Hw 130 Motor Control Shield For Arduino Datasheet Jun 2026

: The HW‑130 (V1) occupies the hardware SPI pins (11, 12, 13), so you cannot use an SD card shield simultaneously unless you bit‑bang a second SPI interface. The V2 version uses only I²C (SDA/SCL) and avoids this limitation.

Check the PWR jumper. If it's off and you haven't connected external power to the shield, the motors won't move even if the Arduino is on. hw 130 motor control shield for arduino datasheet

Ensure you have installed the correct legacy version (V1) of the AFMotor.h library. : The HW‑130 (V1) occupies the hardware SPI
