I would like to use a MicroSD card reader with a Adafruit HUZZAH ESP8266 breakout. My understanding is that the ESP8266 uses the first SPI bus for the flash chip and therefore the second SPI bus (HSPI) must be used for any external devices. Therefore, my question is, is the Adafruit MicroSD card reader supported on the ESP8266 breakout and secondly,if so is there anything I need to know in order to implement this (i.e., different libraries, etc.)?
Thanks,
Jack
