No official HW‑130 schematic exists, but the circuit is a direct copy of the Adafruit V1 shield. The main functional blocks are:
const int dirA = 12; const int speedA = 3; hw 130 motor control shield for arduino datasheet
Connect Coil A to M1 (or M3) and Coil B to M2 (or M4). The center tap (if using a 5-wire/6-wire unipolar stepper) connects to the ground (GND) pin between the terminals. SER1 & SER2: 3-pin male headers for standard 5V RC servos. Pins Utilized by the Shield
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.
The HW-130 Motor Control Shield is a versatile, budget-friendly expansion board designed for Arduino enthusiasts and robotics builders. Based on the classic L293D dual H-bridge motor driver IC, this shield allows you to control multiple motors simultaneously without a messy tangle of jumper wires.
