1. Before using pin4 of CN6 as +3.3V input, the solder bridge SB8 must be removed. Otherwise
the board STM32F469I-DISCO could be damaged by the over-current.
2. The external voltage applied to pin VIN must be in the range from 6 V to 9 V at 25°C ambient
temperature. If a higher voltage is applied the regulator U10 may overheat and could be
damaged.
3. By default pin 5 and pin 6 of connector CN8 are PC5 and PA4 respectively. They are enabled
by the default configuration of solder bridges: SB10 and SB12 closed, SB9 and SB11 opened.
If necessary to have an I2C interface on pins 5 and 6 of connector CN8, change the
configuration solder bridges: open SB10 and SB12, close SB9 and SB11.
