6.3 P2 Pmod
™
and P1 STMod+ connectors
On the 32F723EDISCOVERY board, Pmod
™
and STMod+ connectors are providing
flexibility in small form factor applications.
Based on the existing Pmod
™
Digilent standard popular in connectivity, the
32F723EDISCOVERY board is supporting the Pmod
™
type 2A and 4A on the P2 connector.
P1 STMod+ 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 20: STMod+ connector signals .
Refer to Appendix B: Pmod™ and STMod+ schematic table to find more information about
Pmod
™
and STMod+ pins. Refer to Section Appendix C: 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 U20 STG3692QTR. This quad analog SPDT (Single
Pole Dual Throw) allows to connecting Pmod
™
and STMod+, either to UART or SPI, or both
in the case of STMod+.
