1.
The 3V3 on the pin 4 of the CN14 ARDUINO
®
Uno V3 connector is not a power input for the STM32H573I-DK board. This simplifies the power architecture.
2. The external voltage applied to pin VIN on pin 1 of CN14 must be less than 11.5 V at 25°C ambient temperature. If a higher voltage is applied on the regulator U8, it may overheat and
could be damaged.
3.
By default, the pin 1 and the pin 2 of the CN16 ARDUINO
®
Uno V3 connector are connected to ADC MCU input ports PF12 and PA6 respectively, by configuring the solder bridges:
SB23 and SB24 ON, SB21 and SB25 OFF. In case it is necessary to connect the I
2
C interface signals on pin 1 and pin 2 of CN16, instead of ADC inputs, SB23 and SB24 need to be
OFF, and SB21 and SB25 need to be ON.
