Using a second SDIO on PiZero

cto over 9 years ago

Is the SDIO lines supporting the SD card on the raspberry PiZero the same as the ones on P1?

Is there a way to use those SDIO on P1 to support WiFi?

The SD cards are primaraly a SPI device, as such you technically could parallel anouther device as long as you use a seperate chip select line ut this would then require special driver to know what to use for it. It seems much simpler to use a USB Hub of sorts or an ESP8266 board on the serial lines, depending on what your trying to acheive
