The ESP32 chip has very good multiplexer so you can set the free GPIO pins for alternative functions
via software means.
The SD card interface is in 1-bit eMMC mode.
By default GPIO17 is not lead to the CON1 header to reduce noise on the Ethernet clock line. You can
solder together the pads of jumper GPIO17_E1 if you wish to lead it to the CON1 header.
