How can I install the ESP32-S2 support in Arduino?

[ziv2013]

I have brought a ESP32-S2-Saola-1 from Espressif. And I want to try it with Arduino IDE(in fact I want to try the USB function of S2). But I find I can't find this board in Board Manager. I have tried "Installation Instructions" in the main page, but there is no support for S2.

My question is how can I add S2 support in Arduino?

Thanks in advance.

ESP32 S2 support is in esp32s2 branch.
You have to delete old esp32 installation, if it was done with board manager, and use instructions from Using Arduino IDE with the development repository, then switch branch.

Thanks a lot. I have enabled my USBTiny on ESP32 with your help.

Hello, I tried to copy .json URL from the esp32s2 branch, but it was exactly the same as from the master branch. I am not very familiar with this system, how do I link the correct .json? Am I supposed to modify it somehow?
