CP2102 USB 2.0 to RS232 RS485 TTL 3.3V 5V converter

This FTDI breakout is a super small board with a standard FT232RL USB to serial IC circuit. The pinout fits FTDI cable making it compatible with any Arduino or Arduino compatible 5V boards.

This bidirectional logic level converter can be used with normal series, I2C, SPI and other digital signals. It does not work with an analog signal.
It is very easy to use. The card must be powered from the two voltages (high and low voltage) used by the system.
A high voltage (5 V for example) to the pin "HV", low voltage (3.3 V for example) in "LV", and the system ground to pin "GND". TTL Converter Module 5V - 3.3V Bidirectional 2 Channel I2C Logic Level features:
- 2 high voltage channels and low voltage logic logic for bidirectional translation
- 2 low voltage channels High voltage high voltage logic in unidirectional conversion
- The board module is compatible, it can be inserted directly in the use test panel
- HV to 5 V power

This is a CH340G TTL UART 5V serial adapter, designed to allow adding a USB connection to your project.
In addition, this opens up the possibility of programming microcontrollers like the Arduino Pro mini.
This module allows you to connect your project, from programming small microcontrollers to a custom computer keyboard.
The module is ready for use of a UART connection.
This may require the installation of a driver; however, it is a standard driver distributed by Microsoft Windows Update, available in Linux and that can be configured in MAC OS.
