Wi-Fi Module Row Chip ESP12E
ESP8266 is a small powerful wifi chip that has so many features. Ever since its launch so many companies have produces their own variant of boards. I tried a couple of them and they were cool but some manufacturer do not produce it for certification that directly reflects in defective pieces. that means If something is not working after hours of debugging you will come to know that the module was defective. I was tired of this and wanted to get to a standard always working wifi module (atleast 99%). Then came this module under my search radar ESP-12E.
Its a FCC certificed esp8266 module developed by I guess Ai-Thinker. I quickly got the module in hands and realised that there is no simple way to flash unless you know what you are doing. For people who want to use the module in to a product or application has to either get a development board which contains this module or make their own board. Since I already had got a couple of esp-12e and was not interested in any development board as I have to again find a solution to flash the module in a later timeline. I went ahead to find a solution to flash the module. After many trial and error I found these sites leading me to the right direction.
