Hi , I have also ordered 3 ESP32 Wemos D1 R32 , what i got was kinda the same but different labels.
I have tested one and it worked same as other esp32 boards i tested before . I have tested to power the board from usb and 12V and it was correctly functioning in both cases . I have also attached ws2812b leds to the board ( leds are powered from the board 5v pin ) and i haven’t faced any issue .
Could it be that you guys have got some bad boards somehow ? i still haven’t tested the other 2 boards as i thought i will keep them in the packing in case there is actually a hw issue and in that case i would return them . It is still the case that having the 12V input in the board is good option in some projects but i just realized that the board size is actually too big for my projects and enclosures and hence i personally think that it may not be really a useful option ( even though it is really very cheap ) . Cheers
