Perfect for DIY Scale Projects
This HX711 module works flawlessly with my Arduino Uno. The wiring was straightforward, and the library support is excellent. I built a small kitchen scale in under an hour.

Great value, minor soldering needed
The board functions exactly as described. The pin headers were not pre-soldered on my unit, so be prepared to do a little soldering. Otherwise, accurate readings and stable performance.

Good sensitivity
The gain settings allow for great flexibility depending on the load cell used. Just ensure your power supply is stable to avoid noise in the readings.

Exceeded expectations
Fast shipping and the product quality is top-notch. It integrated seamlessly with my STM32 development board. No calibration issues so far.
Q: Is there a Python library available for Raspberry Pi?
A: Yes, there are several open-source Python libraries available on GitHub specifically designed to interface the HX711 with Raspberry Pi GPIO pins.
Q: Does it support 3.3V logic levels directly?
A: Yes, the module operates within a voltage range of 2.6V to 5.5V, so it is fully compatible with 3.3V microcontrollers like the ESP8266 and STM32 without level shifters.
Q: Can I connect two load cells to this single module?
A: The HX711 has two differential input channels (Channel A and Channel B). You can connect one load cell to each channel, but they cannot be combined for a single heavier reading without external circuitry.
Q: What is the maximum current consumption of this board?
A: The HX711 chip typically consumes less than 1.5mA during normal operation and drops to microamps in power-down mode, making it suitable for battery-powered projects.
Q: Does this module come with a load cell included?
A: No, this package includes only the HX711 breakout board. Load cells must be purchased separately based on your specific weight range requirements.
