Produce Overview[edit]

Overview

The I2C electric level conversion module is specifically designed for Banana Pi. The module convert the 3.3V of I2C electric level to 5V level or convert 5V to 3.3V. The module made by NMOSFET, it makes the module have fast feedback and the low power. There is an pull-up resistor to solve the open-drain output level is not stable.

Produce Features[edit]
