Serial UART TTL to Ethernet Converter


The UART ETH E001 is a converter that provides an easy way for the UART device and Ethernet web server to communicate with each other. It supports multiple serial port and can be configured via web page.


  • Cortex-M3 kernel, optimized LWIP protocol stack, works stably
  • 10/100M Ethernet interface, AUTO MDI/MDIX, supports cross-over and straight-through cables
  • Supports 3 serial ports which feature RTS/CTS hardware flow control
  • Firmware is upgradable via the network
  • Configurable via the built-in web page
  • Supports DHCP-assigned IP, searches devices in LAN by the UDP broadcast protocol
  • Supports keepalive mechanism
  • MAC and port number are configurable
  • Reload button for restoring the module to its factory settings immediately
  • RJ45 indicator
  • Global identical MAC address from IEEE
  • Supports domain name for the web server
  • Configure interface: serial port, Ethernet
  • Working Modes: TCP Server, TCP Client, UDP, UDP Server, HTTPD Client, WEB to Serial
  • Supported protocols: Ethernet, ARP, IP, UDP, TCP
  • Serial port baud rate: up to 1024Kbps for port1/port2, up to 256Kbps for port0
  • Example code: VB/C++/Delphi/Android/IOS (host computer TCP/IP SOCKET program)
  • Provided software: module configuration software, TCP/UDP testing tool, serial port debugging and VCOM virtual serial port software


  • Protection: built-in 2KV electromagnetic isolation
  • Power supply: 3.3V DC or 5V DC (different input pin for each level)
  • Operating temperature: -25~75°C



Application Example

To communicate with web server and/or serial device, it's not necessary for developers to be familiar with TCP/IP knowledge. For instance, in the HTTPD Client mode:
