Description Description The ESP8266 ESP-01 Adapter is used for easier interfacing with the ESP8266 ESP-01 WiFi modules that can be used for wireless communications. A logic level converter is used to allow devices with different voltage levels to communicate (for example, to allow a 5v arduino to communicate with a 3.3v esp8266). Convert 4 pins on the high side to 4 pins on the low side or . This method uses a MOSFET and relies on the parasitic diode between Source and Drain (this is usually a problem rather than a benefit! Ax input 5V TTL level,Bx will output 3.3V TTL level. Following are the technical specifications of logic level shifter. It has one job, which it does flawlessly: it listens to our 3.3V microcontroller data, translates it to a 5V-compatible message, and passes that along to our 5V NeoPixel. This video shows how to use a logic converter to use this chip with a 5v relay. Level-converters, called level-shifter too, are used to adapt between a 3.3V device like the ESP8266 and devices using 5V or more internally. Serial interface is required to program the ESP flash. "i can reply officially here: it is 5V tolerant at the IO. It beats the simple potential divider solution because it can work with any input voltage: simulate this circuit Logic Level Converter. As you can see in the illustration below there is two connection between the ground and the GPIO you need to join these two wire before your going flash the ESP8266 module. 5V Serial Interfacing with ESP8266 or a straight up linear regulator such as NodeMCU Lua Lolin V3 Module ESP8266 ESP-12F WIFI Wifi Development Board with CH340 .
