H-bridge motor driver

The H-bridge motor driver is a board I/O module in the LabWired part catalog. Its catalog type is l298n. It connects to the MCU over GPIO. The catalog gives a supply range of 5–35 V. It has 12 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the H-bridge motor driver in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the H-bridge motor driver (catalog type l298n).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 5–35 V.
  4. Connect ENA and ENB to pins that can output PWM.
  5. Connect IN1, IN2, IN3 and IN4 to free GPIO pins.
  6. Connect OUT1, OUT2, OUT3 and OUT4 as your circuit needs.
  7. Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
