FocusAi I2C logic level converter IIC bidirectional module 5V to 3.3V for Arduino

product description:

Since some MCU development boards and devices work at 3.3V,

There are also single-chip development boards, equipment, sensors, etc. that use 5.0V working power, so when the two need to communicate, there will be inconsistent working voltages, making it inconvenient for users to use.

This product is designed to address and solve this problem. This module provides feasibility in different devices of 3.3V and 5.0V, and acts as a bridge

Module Features:

1. Two-way conversion of high-voltage logic and low-voltage logic for 4 channels

2. One-way conversion of 4 channels of high-voltage logic into low-voltage logic

3. The module is compatible with the breadboard and can be directly inserted into the breadboard for use

4. Realize direct 5V and 3.3V level communication of the serial port

5. The highest stable communication baud rate is 28800bps

6. It can realize bidirectional conversion of 3v-5V level of bus signals such as UART, 1IC, 1-wire, and SPI.

7. Compatibility:

(1) AVCC connected to 5V system power supply

(2) ASCL connected to 5V system SCL

(3) ASDA connected to 5V system SDA

(4) AGND connected to 5V system GND

(5) BVCC connected to 3V system power supply

(6) BSCL connected to 3V system SCL

(7) BSDA connected to 3V system SDA

(8) BGND connected to 3V system GND

Applications:

1. 5V single-chip microcomputer and 3.3V single-chip microcomputer serial port communication.

2. The 3.3V serial port downloader communicates with the 5V single-chip microcomputer serial port.

3. The 5V MCU communicates with the serial port of the 3.3V application module.

Wiring Instructions:

LV(1-4) input and output 3.3V IIL, HV(1-4) input and output 5VTIL, LV(1-4) and HN(1-4) bidirectional mutual conversion
