8.3 PMOD and STMod+ connectors P2 and P1
On the 32F723EDISCOVERY board, PMOD and STMod+ connectors are providing flexibility
in small form factor applications.
Based on existing PMOD Digilent standard popular in connectivity, the
32F723EDISCOVERY board is supporting the PMOD type 2A and 4A on P2 connector.
STMod+ P1 connector uses PMOD signals with extended SPI and spare I/Os for different
peripheral expansion. The related STM32F723IEK6 I/Os for PMOD and STMod+ function
are listed in
Table 18: STMod+ connector signals .
Refer to Section Appendix C: PMOD and STMod+ schematic table to find more information
about PMOD and STMod+ pins. Refer to Section Appendix D: Fanout board to find more
information about STMod+ compatible Fanout board.
The user must select the different configurations using PMOD_SEL_0 (PH15) and
PMOD_SEL_1 (PI10) to control the STG3692QTR (U20). This quad analog S.P.D.T. (Single
Pole Dual Throw) allows to connect PMOD and STMod+: either to UART or to SPI or to both
in case of STMod+.
