User Manual for the correct configuration of the model you are using. CN7, CN8, CN9, and
CN10 are Arduino UNO compatible connectors. CN5 and CN6 are the ST Morpho connectors
that carry most of the MCU signals. Jumper wires can be used to make connections to the
external sensors or devices through these input-output connectors. The Nucleo expansion
