Solid performance
Works well for my robotic arm gripper force feedback system. The sampling rate is adequate for my needs. Just ensure you have a clean power supply for best results.

Great for learning
Bought this for a university project on weight measurement systems. The documentation online is plentiful, and this module made the hardware side very easy to implement.

Exactly as described
Fast shipping and the product matches the description perfectly. The pinout is clearly marked on the PCB, which saved me time checking the datasheet. Highly recommended.

Good value, minor noise issues
Great module for the price. I noticed some electrical noise when running near a motor, but adding a capacitor fixed it. Otherwise, precision is excellent for hobbyist use.

Perfect for DIY Scale Projects
This HX711 module works flawlessly with my Arduino project. The 24-bit resolution provides very stable readings for my kitchen scale build. Setup was straightforward using standard libraries.

Reliable and Compact
I've used several of these modules now for different pressure sensor applications. They are compact, easy to solder, and the gain settings are very useful for different load cells.
Q: Is a library available for Python/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 this module come with header pins pre-soldered?
A: No, the module typically comes without header pins soldered to allow for flexible mounting options. You will need to solder them yourself.
Q: What is the maximum update rate for this sensor?
A: The update rate is selectable via the RATE pin: 10Hz or 80Hz. Most standard weighing applications use the 10Hz mode for better noise rejection.
Q: Can I use this with a 3.3V microcontroller?
A: Yes, the HX711 operates within a voltage range of 2.6V to 5.5V, so it is fully compatible with 3.3V logic systems like many ESP32 or STM32 boards.
Q: How many wires does the load cell need to have?
A: The HX711 supports both 4-wire and 6-wire load cells. For 4-wire cells, you simply leave the sense wires unconnected or bridge them appropriately.
