HX711 weighing sensor Special AD Module

Features: 1. With metal shielding, strong anti-interference, MCU (STC15F104) site binding, secondary development can be upgraded. 2. Two differential input methods can choose. 3. Chip low noise programmable preamplifier, optional gain of 32, 64 and 128. 4. The chip voltage stabilization circuit can be directly to external sensors and chips inside the A/D converter to provide power supply. 5. Chip clock oscillator without any external devices, when necessary, can also use external crystals or clock. 6. Automatic reset circuit. 7. Simple digital control and serial interface communications are all controlled by the input pin, chip registration without programming. 8. Can choose 10Hz or 80Hz output data rate. 9. Suppress 50Hz or 60Hz synchronization power supply interference. Specify: Typical working current: <1.7mA, power current: <1mA. Working voltage range: 2.6~5.5V.
