Hey guys,
last year i had some sad experience with ACT4088 DC-DC Buck Conv. , 50 chips were simply not functioning. And in another order from another seller, everything was fine. Same board, same circuit.
They have explained me that it was 'fake chips". It was my first experience of that kind.
Yesterday i got 40 ESP-12F modules from ebay, and unfortunately, photo was aithinker module and i got "doit.am" module. However, i even realized that such company exist but they don't have same looking module as those that i have got.
40 modules, "barely work". I can program them, "hello world" firmware works fine, however, my original firmware, which is running on normal ESP-12F module very quickly, only sometimes run. In most cases, 95% at least, any wifi connection to and from module is simply not responding. The device can't give IP always etc.
I'm wondering if others have similar experiences? Also, in case anyone had similar problems with ESP-12F?
Check how that one looks:
