Help Identify these programming pods for this Sonoff ESP8285 5v Relay

Hi,

I have this watering equipment. It's basically a 5V solenoid connected to this board.
This board has an ESP8285 and works with SONOFF eWelink APP.

I'd like to flash it with esphome. Since I cannot do it with the DIY mode, I need to flash with the pins.
But the pads to program it have no labels. And I'm a newbie.
I tried to match to an ESP8285 pinout reference, but it's difficult.

Could, please, somebody here help me identify these pads, so I can flash it ?

Thanks a lot !!!
My best regards.

Here are the pictures.

And why didn't the datasheet help you?

Because I'm not sure about the tracks. I could identify TX and RX, but VDD, GND and I think I need GPIO, right? Those I'm not sure.

VDDPST seems to be que 3.3V input. There's VDDA too, but I'm not sure if it's being used.
GPIO0 looks to go to a resistor. GND seems to go nowhere, unless those back tracks are for then...

I'll try the multimeter later. But I think mine is not sharp enough.

Thanks anyway.

Here is where I found anything: https://www.elektroda.pl/rtvforum/topic4058923.html Maybe ask there?
