I’VE BOUGHT AN ESP 8266 (WIFI MODULE) TO MAKE A PROJECT WITH MY FRIENDS BUT I DON’T HAVE ANY “Bi Directional Logic Level Converter” WHEN I TRY TO BUILD THE CIRCUIT ON THE SITE IT ALWAYS ADDS A LLC. I HAVE AN ARDUINO MEGA 2560 INTERNET SAYS IT’S CAN WORK WITH MAXIMUM 3.6V
Hi
You are correct in that the 8266 needs a maximum of 3.6V.
You might be tempted to use the 3.3V supply on the Mega, but that might not work and could damage or destroy your Arduino because you should not draw more than about 50mA from that power supply and the ESP8266 WiFi module can draw around 430mA during startup.
There are a number of options you can use to provide the 3.3V that the ESP8266 needs, but by the sound of it you don’t have any so you’re going to have to buy one I’m afraid. “Buy once, cry once” as they say.
Were you asking to see what options there are, or did I answer your question?
EDIT: Here’s a nice article on treating the ESP8266 nicely. https://www.hackster.io/PatelDarshil/things-you-should-know-before-using-esp8266-wifi-module-784001
Depending on your needs, another option would be to use a microcontroller that also operates at 3.3V such as the MSP430 or the Node MCU (microcontroller and ESP8266 WiFi all in one). That way your entire circuit is at 3.3V (obviously also needs a regulator to bring it down to 3.3V but the communication between the controller and the ESP is simplified).
