This would be a perfect 4808 development board except for the fact that it won't fit a standard 0.1" pitch breadboard. The distance between the header pin rows is 0.75"/19mm rather than a multiple of 0.1".

That said, the board is still fine for my purpose as I wanted a basic working 4808 board to experiment with UPDI programming and testing functions of the 4808 chip before making my own custom board. I can do this with dupont cables directly off the header pins.

The board powered up from the USB port first time and is running some internal code that flashes the LED so it can be seen to be working. The voltage default is set to 3.3V so I had to remove the solder power jumper and change to 5V for my purposes.

It would be useful to have a complete circuit diagram to see how the power supplies and reset circuit works, there is only a pinout and connections to the 4808 shown in the information. (there is a 100nF cap to reset from the RTS pin on the serial port, so the board resets when the serial port is opened)

The expansion connector on the back of the PCB was not fitted to my boards. This was ideal as I don't need it.

There is no schematic available for this board???

I bought a V2 to test. This was so easy to setup with Esphome, It took me 5 minutes. Cool ethernet module Works well! This is a really awesome way to add connectivity for mission critical applications.
You need this config in your project:
ethernet:
type: LAN8720
mdc_pin: GPIO23
mdio_pin: GPIO18
clk_mode: GPIO0_OUT
phy_addr: 1

I have exactly the same issue as Gordon above. Blue LED just stays on a small amount when the light is off in ESPhome. Not a huge issue (other than the presumable wear on the LED strips) as barely noticeable but would like it if this could be resolved. I have 10mm BTF-FCOB RGB's at 24V plugged into the board.

So far, I've installed onto three boards and have the same issue with each. Have attempted GPIO4(g), GPIO5(r) and GPIO6(b). Have also varied with GPIO5(b), GPIO6(g) and GPIO07(r) and the issue persists seemingly no matter the order.

The service from electro dragon has been fantastic and the boards are of really solid quality. Not much choice if you are looking for a non-DIY ESP32 based board. Just wish this LED off issue could be resolved.

Works OK, I am using with 5050 rgb leds with 4 wires, the problem I am having is the LEDs will not turn off. Using either esphome or WLED even when leds’s are off there is still a small amount of light being emitted by the LEDs. Anyone know how I can fix this?

This was delivered yesterday, and within 15 minutes I had it working with 2 64x32 panels to make a 64x64.
Works perfectly.
Now I just need to learn what kind of battery to use for the RTC.
