Compare . You can get breakouts from eBay for a few bucks and there is example code in the OBEX. The HX711 Weighing Sensor uses a two-wire interface (Clock and Data) for communication. The HX711 breakout board also requires a 2.7-5.5V supply, which is the same supply as for the PIC microcontroller in this case. I looked up my 4 amp ATC fuse, and the chart says 5mV across it would mean 219 mA flowing through it. In stock. This driver provides methods to read ADC samples from given channel with given gain. We ship free of charge between branches to complete your order. I'd like to see more isolation to protect from accidents, but without disturbing the mV measurement.
