s 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.</li>
<li>Connect I3C_SCL line of Controller board (PB6 (Arduino SCL/D15 CN5 pin 10, Morpho CN10 pin3)) to I3C_SCL line of Target Board (PB6 (Arduino SCL/D15 CN5 pin 10, Morpho CN10 pin3)).</li>
<li>Connect I3C_SDA line of Controller board (PB7 (Arduino SDA/D14 CN5 pin 9, Morpho CN10 pin5)) to I3C_SDA line of Target Board (PB7 (Arduino SDA/D14 CN5 pin 9, Morpho
