Attention:

1, if the power supply of the high-voltage area and low-voltage area have been common ground, the GND in this module only needs to be connected to 1 ground.
2, the conversion module is equivalent to a straight line, each port corresponds to each other, only the voltage on both sides is not the same, so as to achieve the communication between different levels.
3, this module can not be used as a voltage regulator or transformer function, can only be used for small current communication between IO port levels.
4、This module has no soldered pins, but has matching.

Product Characteristics:

Due to some microcontroller development board and equipment is 3.3V work, and there are also microcontroller development board and equipment, sensors, etc. is the 5.0V working power, so when the two need to communicate, there is a working voltage inconsistency, so that the user is not convenient to use. This product is designed to address this issue and solve this problem. This module provides feasibility in different devices of 3.3V and 5.0V and plays the role of bridging.

Product Parameters:

Self-contained 3.3V voltage output with power indicator, power input with anti-reverse connection protection, and can provide no more than 150mA external current. Stable communication baud rate within 28800bps. Module is compatible with breadboard, can be directly plugged into the breadboard to use.

Product application scope:

1, 5V microcontroller and 3.3V microcontroller serial communication.

2, 3.3V serial port downloader and 5V microcontroller serial port communication.

3, 5V microcontroller and 3.3V application module serial communication.

4、It can realise 5V and 3.3V level communication of serial port directly.

5, can achieve UART, IIC, 1-wire, SPI and other bus signals 3V-5V level bidirectional conversion.
