ESP8266-003 Not detected.
Posted: Mon Oct 17, 2016 11:52 amHello,
I'm new here, on the forum and to electronic in general (well after 10 years of no practice I consider myself as new - a lot changed.)
I was playing a lot with my arduino uno lately and decided to check this famous ESP module after reading a lot about it. So I went with a ESP8266-003 found via ebay.
As everybody know, spacing is problematic on this model so I had to check over the internet about a solution. So after few hours of trial and errors, I went with the setup you can see on the photos.
I think that, somehow, I f**** up the connections while welding as copper left on some of the pins but noneless I tried to connect it to the Arduino, configured as described on the photos.
I'm not sure if the connection to the arduino and pins are correct. I mean, I did read a lot on this forum and over the internet to make sure it was ok. But I don't see any alive connection while monitoring it on the com port. I tried different baud settings but nothing at all.
I read that the 3.3V from the Arduino, was sometime not enough, so I connected it to the 5V output, and I'm afraid to have fried the chips somehow. (I really have to invest in a multimeter).
What do you guy think ? Did I fried it ? Should I tried the same setup with a different (same model) chip ?
Any help or guess is really welcome, thanks !
