This is a placeholder topic for “RGB LED Matrix Panel - 32x32” comments.
Are you looking to add a lot of color to your project? These massive 32x32 RGB LED panels are an awesome place to start. You can create animations, games, or all…
Read moreI would like to use this panel with a WLED ESP32 controller, how would I wire this up from the 16 pin connector?

@Karl110567 Did you check the hook up guide link to Sparkfun web site ??
https://learn.sparkfun.com/tutorials/rgb-panel-hookup-guide
It shows an Arduino UNO and a Mega connected. These have a large number of GPIO pins, your WLED ESP32 would need to have a similar number. The UNO only connects 1 of the GND pins and it only has 13 GPIO pins which is just enough for the display interface.
Alternatively you could use something like this:
I2C only uses 2 pins and the ESP32 should have a built in interface.
I have used one of these expansion boards and it works very well.

Hey @Karl110567,
Just jumping in to second what @James46717 has said.
If you are looking to use an ESP32 controller for this panel, an expansion board would be my recommendation as well.
