20Pcs 4 Channels I2C IIC Logic Level Converter Bi Directional Module 3.3V to 5V Shifter Compatible with Arduino

The bi-directional logic level converter is a small device, can realize bidirectional conversion of UART, IIC, 1-Wire, SPI and other bus signals 3V-5V level, which can safely steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time. This level converter works with 2.8V and 1.8V devices, it can bidirectionally transfer with 4 channels between high logic voltage and low logic voltage. Each logic level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.The board must be operated by the two voltage sources (high voltage, low voltage) that your system uses. The highest stable communication baud rate is 28800 bps. The level converter is very easy to use. 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 ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin. IIC I2C logic level converter bi-directional module Compatible with the breadboard: The level converter is compatible with the breadboard, it can be placed directly on the breadboard
