Hw 130 Motor Control Shield For Arduino Datasheet

Used to connect a second stepper motor.

Note: The HW-130 is a clone/variant of the popular L293D-based motor driver shields (similar to the Arduino Motor Shield Rev3). If you have a specific brand variant, pin functions remain largely the same.

A simple application is controlling a 12V computer fan’s speed and direction. The L293D can handle up to 600 mA continuously, which is sufficient for most small cooling fans.

This approach works because the HW‑130 connects the L293D direction pins directly to Arduino D12/D13 and the PWM pins to D3/D11, bypassing the shift register for those signals. The shift register is only used for brake and the second pair of motors.

: 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.

The HW-130 shield uses two L293D motor driver ICs and one 74HCT595 shift register. This combination minimizes the number of Arduino pins required to drive your motors. 4.5V to 25V DC
