Note:1 Important, before using pin 4 of CN2 as +3.3 V input, insure that the solder bridge SB4 is
removed. Otherwise the 32F412GDISCOVERY Discovery kit could be damaged by the
overcurrent.
Note:2 The external voltage applied to pin VIN should be in the range 6 to 9 V at 25°C ambient
temperature. If a higher voltage is applied, the regulator U3 may overheat and could be
damaged.
Note:3 By default pin 5 and pin 6 of connector CN1 are connected respectively to the port PC5
(ADC1_IN15) and BP0 (ADC1_IN8) of the STM32. They are enabled by the default
configuration of the solder bridges: SB8 and SB6 ON, SB7 and SB5 OFF. In case it is
necessary to have an I
2
C interface instead of ADC inputs on pins 5 and 6 of CN1, have SB8
and SB6 OFF, and SB7 and SB5 ON.
Note:4 Important, before using pin 4 of CN2 as +5 V input, insure the jumpers and solder bridges
are configured according to 5 V DC power input defined in
Section 5.3.1: Power supply
sources . Otherwise the 32F412GDISCOVERY Discovery kit could be damaged by the
overcurrent.
