Soil Sensor 2.2


#1

Hi, I was just trying to solder some cables for flashing to the contacts on a 2.2 board. On the board there are descriptions like “5V G D4 D3 D2 D1 Rx Tx” on one side, “3v3, D8, D7, D6, D5, D0, AD, RST” on the other. I can see the traces to go from ESP Tx -> Tx, Rx -> Rx, gpio5 -> D1, gpio2 -> D4, gpio15 -> R7, but its not clear to me to which pin gpio0 goes (as I need that one for flashing…). In the GitHub 2.1 schematics I can see a pinout that more or less corresponds, but not fully, as pin 6 (marked D1 on the board) should correspond to gpio4, but in reality it seems to be wired to gpio5.

Maybe I did not read this correctly? Or maybe you could tell me which one of the descriptions match gpio0? I can naturally also buy a connector to plug into the flash port. What kind of connector would that be? It seems to be smaller than my standard headers… Or does your rev4 flasher directly plug into the soil sensor flashing connector, with me having to solder anything? If yes, I might just buy one to not have the hassle…

It’s the pinouts compatible with ESPea. We design this for re-use shield from ESPea.

The best flasher for the board is our ESP flasher. You can use it program the sensor easier.

NOTE: ESP soil sensor v2.2 is just v2.1. The schematic is same one.

Do I have to solder anything to the ESP flasher if I buy it? Or does it have the connectors to directly plug it into the flash port?

we’ll solder a pinouts for you if you note us in your order.

Great! I will order immediately…
