Hw 130 Motor Control Shield For Arduino Datasheet [ OFFICIAL — 2026 ]

const int dirA = 12; const int speedA = 3;

Up to 2 stepper motors (unipolar or bipolar) with various stepping modes (single/double coil, interleaved, micro-stepping). Servo Motors: hw 130 motor control shield for arduino datasheet

4 DC Motor channels (or 2 Stepper Motor channels). const int dirA = 12; const int speedA

: 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. const int dirA = 12

The shield fits directly onto the headers of an Arduino UNO. It utilizes specific pins for motor control, internal logic communication, and power routing. Motor Terminal Connections
