Add Lilon S2 mini? #5

Closed martin072 closed 2 years ago

martin072 commented 2 years ago

Hi,

Great work. Would it be possible to add the Lolin S2 (-or C3) Mini? It is 100% pin compatible with the D1 Mini?

See here: https://www.wemos.cc/en/latest/s2/s2_mini.html

I am sorry, but I don't have time at the moment. If it's pin compatible to the ESP32 mini (check here for example image) then I am happy to add a short info in the repo. If not, you could use this as a basis and create a pull request which I am happy to merge.

It is pin compatible with the D1 mini, however the S2 has only 8 pins (well double rows though), like the D1 and not ten then on the device you're showing. So it requires a new layout as the double rows of pins ar now on the inside, not the outside as on your above picture.

The S2 is therefore also in dimensions 100% D1 Mini compatible, making it a extremely nice substitute to the D1 if you have existing PCB's

I am able to modify the Symbol (based on the original ESP32 S2 chip, removed all the pins that have no output on the LOLIN board), but not really understand how to change the PCB layout

Like I wrote, I won't have the time to do any changes to the layout at the moment. But it's not hard to do yourself, so feel free to make the required changes and open a pull request.
