HX711 Load Cell

The HX711 Load Cell is a board I/O module in the LabWired part catalog. Its catalog type is hx711. It connects to the MCU over GPIO. The catalog gives a supply range of 2.6–5.5 V. It has 4 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 HX711 Load Cell in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the HX711 Load Cell (catalog type hx711).
Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2.6–5.5 V.
Connect DT and SCK to free GPIO pins.
Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
