I've got some hardware issue I don't know how to resolve here.
so I got this new esp8266 D1 mini board and soldered it myself. it worked for 2 nights, but the third night, it stopped working.
When I tried to plug esp8266 into a laptop, the blue light won't even flash, the Arduino IDE can't see the part. not even when I connect a battery to it.
initially, I thought it was because I burned it during soldering, but I felt like it should never worked if it was burned. but it did work for 2 days, right?
I tried some dumb methods like blow air into the port it actually works sometimes. but only for a few seconds.
also, I tried different laptops and different cables, nothing worked.
one thing I noticed is that when I wiggle the cable near the esp8266 port, sometimes the blue light flashes. made me think if I got some dirt into the port?
then this morning, I bought isopropyl alcohol to clean it, still didn't work. I seriously don't know what to do. please help
