10 PCS BSS138 8 Channel Logic Level Converter Module

Description:
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. This logic level converter also works with 2.8V and 1.8V devices. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the "VCCA" pin, low voltage (3.3V for example) to "VCCB" pin, and ground from your device to the "GND" pin.

Features:
Chip: BSS138
