[[Category:Hardware]] The STM32MP157F-DK2 provides a connector compatible with the Raspberry Pi 40 pin pinout. Here's a quick reference of the various pins groups. All pins aside power and ground can be used as GPIO unless noted otherwise. Power pins: *3V3 on pins 1 and 17 *5V on pins 2 and 4 Ground pins: *GND on pins 6, 9, 14, 20, 25, 30, 34, 39 I2C pins: *I2C5 SDA on pin 3 (STM32 pin PA12) *I2C5 SCL on pin 5 (STM32 pin PA11) *I2C1 SDA on pin 27 (STM32 pin PF15) *I2C1 SCL on pin 28 (STM32 pin PD12) *I2C5 is I2C1 on the Raspberry Pi *I2C1 is IC20 on the Raspberry Pi MCO pins: *MCO1 on pin 7 (STM32 pin PA8) *MCO2 on pin 29 (STM32 pin PG2) *MCO1 is GPCLK0 on the Raspberry Pi *MCO2 is GPCLK1 on the Raspberry Pi UART pins: *UART3 TX on pin 8 (STM32 pin PB10) *UART3 RX on pin 10 (STM32 pin PB12) *UART3 RTS on pin 11 (STM32 pin PG8) *UART3 CTS on pin 36 (STM32 pin PB13) *UART3 is UART0 on the Raspberry Pi SAI pins: *SAI2 SCKA on pin 12 (STM32 pin PI5) *SAI2 FSA on pin 35 (STM32 pin PI7) *SAI2 SDA on pin 38 (STM32 pin PI6) *SAI2 SDB on pin 40 (STM32 pin PF11) *SAI2 is PCM on the Raspberry Pi *SAI2 pins are only usable as GPIO unless you desolder some bridges (see the user manual) SDMMC pins: *SDMMC3 CK on pin 15 (STM32 pin PG15) *SDMMC3 CMD on pin 16 (STM32 pin PF1) *SDMMC3 D0 on pin 18 (STM32 pin PF0) *SDMMC3 D1 on pin 22 (STM32 pin PF4) *SDMMC3 D2 on pin 37 (STM32 pin PF5) *SDMMC3 D3 on pin 13 (STM32 pin PD7) *SDMMC3 is SD0 on the Raspberry Pi SPI pins: *SPI5 MOSI on pin 19 (STM32 pin PF9) *SPI5 MISO on pin 21 (STM32 pin PF8) *SPI5 SCK on pin 23 (STM32 pin PF7) *SPI5 NSS on pin 24 (STM32 pin PF6) *Chip select GPIO on pin 26 (STM32 pin PF3) *SPI5 is SPI0 on the Raspberry Pi *SPI5 NSS is SPI0 CE 0 on the Raspberry Pi *Chip select GPIO is CE 1 on the Raspberry Pi Timer pins: *TIM5 CH2 on pin 31 (STM32 pin PH11) *TIM4 CH2 on pin 32 (STM32 pin PD13) *TIM3 CH2 on pin 33 (STM32 pin PC7) *TIM4 CH2 is PWM0 on the Raspberry Pi *TIM3 CH2 is PWM1 on the Raspberry Pi
