Product description
4-channel bi-directional logic level converter for I2C and other slow digital interfaces. The module is based on BSS138 FETs with 10K pull-ups and is used to adapt logic levels between systems such as 5V and 3.3V devices. It is intended for logic level conversion and not for driving loads from the high-voltage side.
