RGB64x32MatrixPanel on ESP32

For a friend I'm making a RGB LED panel, and need to pull some social media numbers and display them on the panel.

For this I wanted an ESP32 so it could do HTTP REST calls over wifi. I came across this library for efficiently talking to HUB75 RGB panels on an ESP32:

Parts List

MCU Pin Issues

The MCU has several pins with limited functionality or they are not connected. The wiring guide suggests using pins 16/17 for example, but on WROVER they aren't connected.

The final mapping I used is:

IO2  G2
IO4  LAT
IO5  C
IO18 CLK
IO19 B
IO21 B2
IO22 OE
IO23 A
IO25 R1 
IO26 G1
IO27 B1
IO32 R2
IO33 D

Platformio.ini

The LilyGo TT T7 isn't in Platformio yet, but using a T1 works too:
