Hi there,

I recently purchased the HX711 weight sensor kit, alongside the I/O expansion shield and the DFRduino UNO R3.

I've constructed the weight sensor kit and connected it to the DFRduino, via the expansion shield.

Unfortunately, I get the error: “The initialisation of the chip is failed, please confirm whether the chip connection is correct” when I try to run any of the example codes for reading weights / calibrating the scales in the IDE.

All three parts are receiving power. I have two expansion shields and swapping them doesn't seem to make a difference. My baud rate is set to 9600. My DFRduino runs test codes such as ‘blink’ fine. Does anyone have any advice / suggestions if there is anything I can try before I buy and try a new weight sensor kit?

Hope that all makes sense. This is my first ever project so I'm very new to all this.
