ESP8266 -> FTDI -> USB Mac
I followed the wiring on this page: http://williamdurand.fr/2015/03/17/playing-with-a-esp8266-wifi-module/
I was communicating with it via Serial at 115200. I issued a
AT+UART_DEF=9600,8,1,0,0 and a few seconds later I looked over and it was smoking.
I bought 2 of these. The previous one I had wired to an Arduino Nano running through a logic level converter. That one only returns
Exception (28) over and over again after issuing that same command.
On both units
AT+GMR AT version:0.40.0.0(Aug 8 2015 14:45:58) SDK version:1.3.0
Are these units too hard to use? What did I do to burn it out?
Answer given was that I fed it 5v instead of 3.3v. Obvious. I didn't think I did but I checked the output of the FTDI and sure enough it was 5.1v. So why does the output on it say 3V3 ? I thought that meant that it was 3.3v...
Should have checked it first.
