Supply note: the source lists 2.6–5.5 V for the HX711 module and 3–15 V as a recommended operating voltage for the load cell. These are component ratings; the module supply must stay within the HX711 board’s rating. Check the exact board wiring and ratings before applying power. Do not exceed the load cell’s rated capacity.
