n: PB6 (Arduino SCL/D15 CN5 pin 10, Morpho CN10 pin3) to PB6 (Arduino SCL/D15 CN5 pin 10, Morpho CN10 pin3)
  - SDA Pin: PB7 (Arduino SDA/D14 CN5 pin 9, Morpho CN10 pin5) to PB7 (Arduino SDA/D14 CN5 pin 9, Morpho CN10 pin5)
  Connect GND between each board
  Use short wire as possible between the boards or twist an independent ground wire on each I3C lines
  mean one GND twist around SCL and one GND twist around SDA to help communication at 12.5Mhz.</code></pre>
