CH340G USB to RS232 TTL Auto Converter Adapter Module for Arduino
Description:
CH340G USB to RS232 TTL Auto Converter Adapter Module is a versatile and highly useful module for enabling communication between an Arduino board and RS232-based devices via USB. This converter module is equipped with the CH340G USB-to-TTL chip, which allows for easy conversion of signals between RS232 and TTL serial levels. This makes it a perfect solution for interfacing your Arduino projects with legacy RS232 devices, such as industrial equipment, sensors, and communication devices that use the traditional RS232 standard.
This module provides a simple interface for both sending and receiving data between the Arduino (or other microcontroller boards) and RS232 peripherals, making it ideal for developers and hobbyists working with embedded systems or custom electronics. The module’s compact form factor and plug-and-play functionality make it a perfect addition to various projects requiring reliable serial communication.
Features:
1. CH340G USB to RS232 TTL Chip
2. RS232 to TTL Conversion
3. Wide Voltage Compatibility
4. USB Interface
5. UART/TLL Output Pins
6. Ideal for Arduino Projects
7. Small Form Factor
8. Versatile Application Scenarios
