5pcs 4 Channels Logic Level Converter Bi-directional Shifter Module
Pre-Soldered 4 Channels IIC I2C Logic Level Converter Module
The I2C Logic Level Shifter is a versatile electric workhorse, serving a wide range of applications, compatible with Raspberry Pi and Other Microcontrollers.
This 4 Channels level shifter's ability to ensure seamless communication is invaluable. It doesn't just bridge the voltage gap; it does so with precision and reliability, budget-friendly price
Multi-Channel Versatility: 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.
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.
Even better, this IIC I2C Logic Level Converter is ready to be plugged in since it already has soldered pins. Safety and Save time.

Pins
TX0: Data transmitted from this channel on the high-voltage side will be received on the corresponding RX0 channel on the low-voltage side.
RX0: Data transmitted from the TX0 channel on the low-voltage side will be received on the corresponding RX0 channel on the high-voltage side.
TX1: Data transmitted from this channel on the high-voltage side will be received on the corresponding RX1 channel on the low-voltage side.
RX1: Data transmitted from the TX1 channel on the low-voltage side will be received on the corresponding RX1 channel on the high-voltage side.
LV (Low Voltage): LV represents the low voltage side or the side of the circuit that operates at a lower voltage level.
HV (High Voltage): HV represents the high voltage side or the side of the circuit that operates at a higher voltage level.
GND (Ground): GND represents the ground or common reference voltage for both the low voltage (LV) and high voltage (HV) sides.
