Hi all
i orderd 2x 5pcs D1 Mini from CN different Distributors
and well i discoverd that there where diferences in the Pinout GPIO
as many now post simular
IF you got run into this problem
FIRST if you see only 2 LED light GREEN/White you are at the same problem
Configured GPIO 4 =D2 on the PCB
If you have still not found your GPIO !!
Configure the GPIO to Relay set 2presets Relai on /Relai off
USE a meter and see what pin changes Value on Togeling relai on/off
this helped me to get around the problöem
SOME PCB got Version Numbering but not all as i recived
ok 1USD is the count so NP on me it workes fine so far
