if the STM32 does not embed a UCPD peripheral, connect JP2 and JP3 jumpers to CC1_noUCPD and
CC2_noUCPD, respectively.
development board, the expansion board can be supplied in two different
ways:
•
through the
supply by using the development board internal LDO;
•
through the CN3 screw connector and thanks to the integrated
LDO linear regulator (U2) that
supplies the entire system.
