7Semi CH343 USB-A to UART TTL Converter

The 7Semi CH343 UART Module provides a convenient USB-to-TTL UART interface for connecting computers with microcontrollers, development boards, embedded systems, and serial devices. It converts USB data into standard UART TX and RX signals, allowing the computer to communicate directly with the connected hardware. 

The module can be used for development, serial monitoring, configuration, testing, and troubleshooting applications. Users can connect TX, RX, and GND to the target system and use standard serial-terminal or development software to exchange data and monitor device messages.

Key Features:

• High-Speed Data Transfer:
  Supports transmission rates from 50bps to 6Mbps, ensuring rapid and stable communication.
• Adjustable TTL Levels:
  Supports 3.3V and 5V TTL level switching, allowing flexible voltage configuration.
• USB Type-A Interface:
  Features a durable and user-friendly USB-A port with resettable fuse (500mA) and ESD protection for long-term reliability.
• Automatic Baud-Rate Adaptation: Automatically detects and adapts to communication baud rates up to 115200 bps.
• Hardware Flow Control: Supports RTS and CTS signals through dedicated exposed pins for reliable UART communication.
