Excellent sensitivity
Connected this to a 5kg load cell and the precision is impressive. It can detect weight changes as small as a single gram without drifting too much over time.

Good value, small footprint
Compact size fits easily into tight enclosures. Signal noise is low when properly grounded. Only giving 4 stars because the pin headers were not included, had to solder my own.

Best in class for the price
I have tried several different ADC modules, and this compact version offers the best balance of size, price, and performance for embedded weighing applications.

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

Reliable and Precise
We used ten of these for a student robotics competition. All units performed consistently. The ability to switch between 10Hz and 80Hz sampling rates is a nice feature for filtering noise.

Works as advertised
Standard HX711 performance. Documentation online is plentiful which helps beginners. Make sure you use a stable power supply to get the best accuracy.
Q: What is the maximum length for the wires connecting the load cell to the module?
A: For optimal signal integrity and noise reduction, we recommend keeping the load cell wires under 1 meter. If longer distances are required, shielded cables are strongly advised.
Q: Does this module come with a load cell included?
A: No, this listing is for the HX711 amplifier module only. You will need to purchase a compatible load cell separately based on your weight capacity requirements.
Q: Can I use this with a 3.3V microcontroller like the ESP32?
A: Yes, the module operates within a voltage range of 2.6V to 5.5V, making it fully compatible with 3.3V logic systems such as the ESP32 and Raspberry Pi.
Q: Is there a library available for Python on Raspberry Pi?
A: Yes, there are several open-source Python libraries available for the Raspberry Pi GPIO, such as 'hx711' or 'pi-hx711', which can be installed via pip to simplify integration.
Q: How do I switch between 10Hz and 80Hz sampling rates?
A: The sampling rate is selected by the number of clock pulses sent after a data read. 25 pulses select Channel A at 10Hz, 26 pulses select Channel B at 10Hz, and 27 pulses select Channel A at 80Hz. Most libraries handle this automatically via configuration.
