Hi @barsikus007, there is no official variant for this board, so a proper variant header should be added to this repo https://github.com/espressif/arduino-esp32 in the first place.

Looks like it already exists as variants makergo_c3_supermini and nologo_esp32c3_super_mini. Not sure if Maker go was the original designer and the "nologo" one is for clones/resellers, or what (apparently, Nologo is an actual manufacturer). They look essentially the same to me.

thanks, but I haven't these boards in platformio
how to add them?

The boards will be added once a new stable version of the framework is released.

thanks, I'll just wait for release and will use nologo_esp32c3_super_mini one

I have a esp32 c3 super mini board but i am not able to flash it

[vbguyny]

Does anyone know when there will be an update available with support for the super mini?

[valeros]

@vbguyny It will be added once a new stable release of Arduino core is published.

I wouldn't count on that happening any time soon, though. Neither of the above-mentioned board variants is present in the v2.x release branch of arduino-esp32, and it looks like 3.0.0 is still in pre-release. I have no insight into the release schedule for that, but even once released, there seems to be some uncertainty around getting that version supported by platformio.

In the meantime, you can pretty much use any of the existing ESP32-C3 variants that don't have a separate USB serial chip on the board (I use lolin_c3_mini), as long as you don't use the board-specific Arduino pin macros like LED_BUILTIN, etc. And if you really need those, I think you can copy one of the pins_arduino.h files that got added in arduino-esp32 (from here or here) into your project somewhere in the -I header include path.

There is a PR branch available with the small changes needed to get PlatformIO to work with Arduino-ESP32 v3.0.0. #1281

However, you will still need to update your board configuration for any new boards, plus your code may simply not work with 3.0.0 due to various breaking changes. But the above change will at least let PlatformIO run the compile to find out what is broken.

Hi any news on this? PlatformIO is already using the esp32 v3.x, isn't it?
