board I/O module

L293D

The L293D is a board I/O module in the LabWired part catalog. Its catalog type is l293d. It connects to the MCU over GPIO. It has 16 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 L293D in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the L293D (catalog type l293d).
  3. Connect L1, L2, L3, L4, L5, L6, L7, L8, R1, R2, R3, R4, R5, R6, R7 and R8 as your circuit needs.
  4. Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
