FireBeetle Board ESP32-E using WLED

Support
1

Hi.
Hoping someone can point me in the right direction.
I just received a new FireBeetle Board ESP32-E DFR0654 and I would like to use it with WLED.
I have successfully installed the software and am about to start wiring it up to the LED strip but noticed that there is no “pin4” that is normally used for the data/signal channel for the LED’s.

The board does however have the following options and I was not sure which one to use:
A4
D4
SDA

Can you please let me know as I do not want to fry the board.

Thank you
Gary

Just a quick typo correction from my initial post. There is no D4 pin. All the options available are:
RST
3V3
GND
EN
SCK
MO
MI
SCL
SDA
D7
D6
D5
D3
D2
TX
RX

VCC
3V3
GND
SCL
SDA
A4
A3
A2
A1
A0
D13
D12
D11
D10

I have connected the:
GND wire of the LED strip to the GND connection on the ESP
5v wire on the LED strip to the VCC connection on the ESP
Now just wondering where to connect the data/signal wire on the LED to on the ESP.

Thank you.

Welcome Gary!

D12 will be the pin you are after.

Unfortunately the information is abstracted through the pinout but checking out the schematic is the fastest way to figure it out.

Other ESP32 modules such as Unexpected Maker, Adafruit and Sparkfuns offerings are a lot more in-depth and intuitive.

Let us know how you go!

Thank you Liam. I have now connected to D12 and configured WLED to GPIO4 and this has worked. Very much appreciate you clearing up my confusion.
