It is also compatible with Raspberry Pi and ESP32\/ESP8266 platforms using the appropriate HX711 library.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the advantage of the on-board TL431 external reference voltage?\u003c\/h4\u003e\n\u003cp\u003eA: The TL431 is a precision programmable shunt regulator that provides a stable, accurate reference voltage to the HX711 ADC. This reduces drift and noise in measurements compared to modules relying solely on the supply voltage as a reference, resulting in more consistent and repeatable load cell readings.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I connect two load cells at the same time?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This module features a dual-channel interface (Channel A and Channel B), allowing you to connect and switch between two separate load cell inputs. Channel A supports programmable gain of 64 or 128, while Channel B supports a fixed gain of 32, making it suitable for a wide range of sensor sensitivities.\u003c\/p\u003e\n\u003ch4\u003eQ: What supply voltage does this module require?\u003c\/h4\u003e\n\u003cp\u003eA: The module operates on a 5V supply voltage, making it directly compatible with standard Arduino power outputs without the need for any additional voltage regulators.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this HX711 ADC module compatible with Arduino boards?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, the HX711 24-Bit ADC module uses a simple 2-wire serial interface (CLK and DOUT pins) that works directly with Arduino Uno, Nano, Mega, and other compatible microcontrollers.
