Hw 130 Motor Control Shield For Arduino Datasheet ((link)) Today

On the board, near the power terminals or the logic chip, you will often see jumper pads or actual jumpers.

The shield has a jumper that connects the motor supply voltage to the Arduino’s 5V regulator input (Vin). hw 130 motor control shield for arduino datasheet

No official HW‑130 schematic exists, but the circuit is a direct copy of the Adafruit V1 shield. The main functional blocks are: On the board, near the power terminals or

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. On the board
