23 / 48 page ![]() DocID029078 Rev 2 23/48 UM2032 Hardware layout and configuration 47 Note:1 Important, before using pin 4 of CN2 as +3.3V 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 9V 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 closed, SB7 and SB5 opened. In case it is necessary to have an I2C interface instead of ADC inputs on pins 5 and 6 of CN1, open SB8 and SB6, and close SB7 and SB5. 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 6.3.1: Power supply sources. Otherwise the 32F412GDISCOVERY discovery kit could be damaged by the overcurrent.
