Re: Small ESP32 Modul ( all include in new ESP32-PICO )

TTGO Micro-32 Unfortunately doesn't have any certifications, so is good only for hobby brewery,

Plus looks bigger in size than Espressif's Engineering sample with the 3D antenna ;)

Thanks

Re: What would you like to see in The Next Chip?

BTW - do you intent to continue the approach you took with ESP32-S2 and make ESP32-B2 :) or sort of - ESP32 with BT only (without WiFi)?
What are the plans regarding new versions of Bluetooth implementation?
Thanks

Ok, finally found time to play back with this board: Problem solved thanks to krzychb! Thanks! So the problem was this capacitor C15 that is soldered parallel to BOOT button (I0).
