I have searched some projects that uses ESP8266 only to send email, etc, and every time I did it, my WiFi module would heat up quite quickly. So I searched up further, and some said that it was never recommended to use the module on its own. It got rather confusing so I decided to make a post.
I have two questions:
- I have wired the module like this and it would heat up quickly with a red LED. Is this guide correct? If not, how should I wire it?
- Is it alright to use the module on its own?
