Description

I2C/Serial Bi-Directional device to safely connect 5V MCUs to 3.3v Modules If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. This bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. * Standalone module, no external components required * The level converter is very easy to use, just put in series with connection wires * On-board 3.3 voltage regulator, BSS138 FETs, pull-up resistors and power LED * 2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I2C application
