Appendix B STMod+ GPIO sharing and multiplexing
Table 27 describes the signals available on the STMod+ connector. It also shows which signal is shared with other
board connectors (such as camera, ARDUINO
®
Uno V3, DFSDM, or Wi‑Fi
®
). Solder bridges (SB) are present to
manually select which function is wired by default.
Analog signals are in brackets [xxx].
The I
2
C bus is shared with the ARDUINO
®
Uno V3 connectors. It is recommended to check the device slave
address when adding it to the bus.
