Settare program as TTG0 T1 as you see from the picture that I put. But to program the esp32 should press the button "boot". Still works fine.

As described.
Goods not delivered. AliExpress refund.
Ordered "in the kit" to the already available keyestudio esp32-io shield of the same store, as it turned out, that I have esp32-wroom-32d devkitc too "wide" for it (approximately 2mm). Everything works, only, at first glance, the sensitivity of the WiFi receiver * is noticeable * worse, although visually MIFA antenna is the same. --- I 've ordered it "as the kit" for the existing keyestudio supplier shield of the same seller, as it turned out that my supplier devkitc was too "wide" for it (approx. 2mm). Everything works, only, at first glance, the supplier of the WiFi receiver is * noticeably * worse, although visually the MIFA antenna is the same.
Packaging is not and guarantee damage to the findings of MS, For such money it would be better to pack.
