@ -78,5 +78,7 @@ pin 16 is used for psram but you may get away with using it as input for a butto
You could also use 1 and 3 if you do not use Serial or 14,2&15 if not using SD Card
Other possible pins you could solder directly to the esp32 module? 17, 9, 10, 11, 6, 7, 8

Another option (which I have not actually tried yet) would be to attach a MCP23017 Bidirectional 16-Bit I/O Expander (possibly need to use the serial tx and rx pins) which would then give you 16 gpio pins to play with :-)
