Product Introduction

The working voltage of microcontrollers and devices is 3.3V, and some microcontrollers, devices, and sensors also have a working voltage of 5.0V; When the two need to communicate, there is a situation where the working voltage is inconsistent; The module provides feasibility in different devices with 3.3V and 5.0V, serving as a bridge.

Product Features

(1) Unidirectional conversion from high voltage logic to low voltage logic

(2) The module is compatible with breadboards and can be directly plugged into them for use

(3) Realize direct communication between 5V and 3.3V levels via serial port

(4) The highest stable communication baud rate is 28800bps

Product 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 3.3V system power supply

(6) BSCL connected to 3.3V system SCL

(7) BSDA connected to 3.3V system SDA

(8) BGND connected to 3.3V system GND

This module can only convert 5V voltage from channel A to 3.3V voltage from channel B, and cannot convert 3.3V voltage from channel B to 5V voltage from channel A
