The Stellaris® Serial-to-Ethernet Reference Design Kit (RDK-S2E) offers a complete, open-tool, and ready-to-implement solution designed to add web connectivity to any serial device. Included in the RDK-S2E is the tiny-footprint Luminary Micro Stellaris Serial-to-Ethernet Module (MDL-S2E). The most common application for the MDL-S2E is for augmenting legacy products that only contain a serial port for a configuration or control interface. In addition, newer computers, especially laptop computers, do not necessarily have serial ports, and a serial connection is limited by cable length (typically 10 m). Simply installing a Stellaris Serial-to-Ethernet Module into the legacy serial device provides many benefits including no major board redesign or software changes, easy sharing on a network other than Ethernet, tiny form-factor for unobtrusive implementation, and 10-meter maximum cable length for serial connections is no longer a limitation.


The MDL-S2E is the first serial-to-Ethernet converter available with a highly integrated Cortex™-M3 microcontroller with 50 MHz of performance and ample single-cycle, on-chip Flash and SRAM memory for efficient network traffic handling. For maximum space savings, the Stellaris microcontroller is offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHY on-chip.

The RDK-S2E ships with the MDL-S2E module. The MDL-S2E is a ready-for-production serial-to-Ethernet module with the following features:

  • LM3S6432 in a 10 x 10 mm BGA package for reduced board size
  • 10/100 Mbit Ethernet port
  • Auto MDI/MDIX cross-over correction
  • Traffic and link indicators Serial ports
  • UART ports include RTS/CTS for flow control
  • UART0 has RS232 levels, transceiver runs at up to 230.4 Kbaud
  • UART1 has CMOS/TTL levels, can run at 1.0 Mbaud
  • Software
    • IP configuration with static IP address or DHCP
    • Telnet server for access to serial port (VCP software included)
    • Web server for module configuration
    • UDP responder for device discovery
    • Telnet client for Ethernet-based serial port extender
    • Module supports 5 V and 3.3 V supplies
    • Multiple mounting options
    • JTAG port pads for factory programming

Kit Contents

While the MDL-S2E is ready out-of-the-box for immediate integration in a system, complete software source files are included for simplified customization.

  • Stellaris® Serial-to-Ethernet Module (MDL-S2E) RS-232 adaptor board
  • Retractable Ethernet cable
  • DB9 serial cable
  • USB cable
  • Reference Design Kit CD containing a Quickstart Guide, User's Manual, Software Reference Manual, Board Data Sheet, source code, BOM, schematics, and Gerber files
