GPIO port

gpio port the gpio port is an expansion connector for external hardware modules it exposes 3 3 v and 5 v power rails (both efuse protected up to 2 a), usb 2 0 data lines, and a mix of mcu and cpu gpio pins, which can be configured as pins for i²c, uart, spi, can, pwm, i²s, spdif, and adc inputs, as well as pio (programmable i/o) pins gpio port schematic gpio port pinout flipper one gpio port pinout description pin pin description 3 3 v power, up to 2a efuse 3v3 gnd ground mcu gpio 40 pio adc0 pwm8 a m40 m41 mcu gpio 41 pwm8 b adc0 pio cpu gpio4 b4 d spdif rx0 m0 i2c3 sda m0 uart2 rx m1 can1 rx m2 b4 b5 cpu gpio4 b5 d can1 tx m2 uart2 tx m1 i2c3 scl m0 spdif tx0 m0 cpu gpio4 b2 d sai1 sdo3 m0 sai1 sdi1 m0 pdm1 sdi1 m1 spi4 miso m2 b2 b3 cpu gpio4 b3 d pwm2 ch7 m0 spi3 csn1 m2 spi4 csn0 m2 pdm1 sdi0 m1 sai4 sd0 m0 sai1 sdi0 m0 cpu gpio4 b0 d sai1 sdo1 m0 sai1 sdi3 m0 pdm1 clk1 m1 spi4 clk m2 uart5 tx m1 uart6 rtsn m0 uart2 rtsn m1 b0 b1 cpu gpio4 b1 d uart2 ctsn m1 uart6 ctsn m0 uart5 rx m1 spi4 mosi m2 pdm1 sdi2 m1 sai1 sdi2 m0 sai1 sdo2 m0 cpu gpio4 a6 d sai4 lrck m0 pdm1 clk0 m1 spi3 miso m2 i2c4 sda m1 uart6 rx m0 can0 rx m2 a6 a7 cpu gpio4 a7 d pwm2 ch6 m0 spi3 clk m2 sai4 sdi1 m0 sai1 sdo0 m0 cpu gpio4 a4 d sai4 sclk m0 pdm1 sdi3 m1 spi3 mosi m2 i2c4 scl m1 uart6 tx m0 can0 tx m2 a4 a5 cpu gpio4 a5 d i2c2 sda m2 uart5 ctsn m1 spi4 csn1 m2 sai1 lrck m0 cpu gpio4 a2 d sai1 mclk m0 sai4 mclk m0 pwm2 ch5 m0 a2 a3 cpu gpio4 a3 d pwm2 ch4 m1 i2c2 scl m2 uart5 rtsn m1 spi3 csn0 m2 sai1 sclk m0 5v power, up to 2a efuse 5v gnd ground cpu usb 2 0 data+ d+ d cpu usb 2 0 data
