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 v...
