Our first batch of ESP32-ADF is sold out now we work on second batch but will have no time to complete before our Summer vacation, so new stock will be available after August 18th.
For these who didn’t managed to get one there is notification link on the product page which will notify you when the board is back in stock.

Will the new batch include a fix, so that no wire is required?

Oh, I see, now saw it on the photos too (was wondering why they wеre with such a low resolution 😀 )
Isn’t too bad for a dev board 🙂
