8.3 Pmod™ and STMod+ connectors P2 and P1
On the STM32F7308-DK board, Pmod™ and STMod+ connectors are providing flexibility in
small form factor applications.
Based on existing Pmod™ Digilent standard popular in connectivity, the STM32F7308-DK
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 STM32F730I8K6 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+.
