@ -94,6 +94,7 @@ GPIO PINS:
<br>BTW-You can use an MCP23017 io expander chip on pins 12 and 13 to give you 16 general purpose gpio pins, this requires the adafruit MCP23017 library to be installed.
<br>Pin 16 is used for psram but you may get away with using it as input for a button etc.?
<br>Note: I have been told there may be issues reading files when sd-card is in 1-bit mode, I have only used it for writing them myself.
<br>Some good info here: https://github.com/raphaelbs/esp32-cam-ai-thinker/blob/master/docs/esp32cam-pin-notes.md
