24 / 48 page ![]() Hardware layout and configuration UM2032 24/48 DocID029078 Rev 2 6.16 Extension connectors P1 and P2 The extension connectors consist in male pin headers P1 and P2 (not soldered by default). They provide access to the following IPs of the STM32F412ZGT6: • SPI • I2C with SMBA and FM+ (1 MHz speed) • Full USART (Rx, Tx, RTS, CTS) • CAN • ADC inputs • TIMERs channels • I2S full duplex with SD and extSD alternate functions. • DFSDM input for stereo PDM digital microphones Most of the ports connected to the extension connectors P1 and P2 are the same for the 32F401CDISCOVERY and 32F411EDISCOVERY discovery kits, to maximize the compatibility with the previous designs. In Table 6, Table 7 and in the 32F412GDISCOVERY schematics (see Section Appendix A: Schematics), the pin numbers corresponding to these ports, are annotated with the star symbol: “*”. In Table 6, Table 7 and in the 32F412GDISCOVERY schematics (see Section Appendix A: Schematics) the pins belonging to the extension connectors P1 and P2 annotated with a letter, are shared with a peripheral of the 32F412GDISCOVERY (for example, S means that the port PC9 corresponding to pin 46 is also used for microSD, see Table 7).
