Description
Based of of https://easyeda.com/A74Martel/2-channel-i2c-level-shifter This I2C Bi-Directional IO Expander is meant to safely connect 5V MCUs to the 3.3v PCF8575. 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 !6 port IO using PCF8575
