I was trying to setup a swan MCU for my project to use with Notecarrier. The issue, I encountered was that it was a long setup of installation steps and after following the steps, the Arduino
I was going through the datasheet of the notecarrier-AF and found the pin usage saction but I still doubt that those are the only pins to be used as there is not GND mentioned in that list. FYI, I am only using the I2C communication to transfer the JSON data.
Also, I am using Arduino so I will use Notecard.begin() function to start I2C communication.
Can anyone tell what are the pins which I need to connect to the feather or breadboard-able connectors from Arduino supported boards such as Uno, Nano or evern nRF based boards?
One of the main concern to ask is that powering the boards in wrong manner may damage the notecard etc. Also, as far as I know when we use two supplies for connected circuits we need to provide a common grond.!
