A logic level converter is a mediator so that two devices can communicate which works on different voltage level.
For example ESP8266 Wifi modules works on 3.3 Voltage level thus it will communicate on 3.3V level on RX an TX but a if micro controller is to be attached with this module that works on 5V level thus this micro controller will communicate on 5V level in RX and TX. So this logic level converter will be required between both of them.
2. Connection for logic level converter
The following four connection will be required.
2. Connection for logic levels
Following connection will be needed to made. It not necessary to use all four logic level, You may use 1,2,3 or 4 at a time. Robo India's Logic Level Converter can convert maximum 4 logic at a time.
Logic will be converted in the following manner. Each logic has its corresponding high / low logic level.
