Adafruit 4-channel I2C-safe Bi-directional Logic Level Converter

A 4-channel I2C-safe Bi-directional Logic Level Converter ensures seamless communication between 5V and 3.3V devices. Equipped with open-drain outputs and 10K pull-ups, this converter is optimal for interfacing tasks. It's designed specifically for I2C systems but also supports TTL Serial and slower SPI protocols.

Features include an array of four BSS138 FETs with pull-ups, accommodating low-side voltages down to 1.8V and high-side up to 10V. The converter maintains functionality with slower data transfers, providing reliable logic level conversion without driving high-side loads.

This versatile board merges ease of use with I2C compatibility, offering a practical solution for projects requiring level shifting. While ideal for I2C applications, it adapts to alternative connectivity demands, illustrating its flexibility in a variety of scenarios.
