2.6 ADC OR I2C COMMUNICATION
If ADC or I2C communication is required, you can connect the ADC interface or the I2C interface
to the Arduino connector or the ST Morpho connector by setting the JP5.
Here are the relative settings to JP5:

The pins A4 and A5 of JP5 should be connected to the Arduino connector on the pins A4 and A5 (the
pin 5 and the pin 6 of CN8) or the ST Morpho connector on the pins 36 and 38 of CN7 respectively;

The pins SDA/PB9 and SCL/PB8 of JP5 corresponding to the I2C interface of STM32 MCU;

The pins PC1/ADC and PC0/ADC of JP5 corresponding to the ADC interface of STM32 MCU.
