I 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 ??

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.
