World's smallest Linux webserver?

Oct 16, 2009 — by Rick Lehrbaum 2,193 views

[Updated Dec 24, 2013] — Lantronix has introduced what it claims is the “World’s Smallest Linux Networking Server.” Within an elongated RJ45 Ethernet LAN connector, the XPort Pro packs a 32-bit Freescale Coldfire SoC, up to 16MB SDRAM, 16MB flash storage, and a 10/100Mbps Ethernet LAN port.

This little gadget isn’t aimed at heavy lifting chores, though. Its control-oriented features includes:

  • SoC:
    • 32-bit Freescale MCF5208 SoC
    • Version 2 ColdFire variable-length RISC processor core
    • clocked at 166MHz
  • Memory:
    • 8MB or 16MB SDRAM
    • 16MB flash
  • LAN port — 10/100Mbps Broadcom Ethernet PHY
  • Serial ports — high-speed (300 to 921,600 bps) RS232 serial port with hardware handshaking
  • GPIO — up to three configurable I/O pins (two are shared with DTR and DCD); not 5V tolerant
  • Operating temperature — -40 to +85° C
  • Input power — regulated 3.3V input required



Inside the XPort Pro

 

According to Lantronix, the XPort Pro runs a choice of Linux or the company’s “Evolution OS.” The latter includes a “full featured” TCP/IP stack, built-in webserver, and supports the following protocols: ARP, IP, UDP, TCP, ICMP, BOOTP, DHCP, Auto IP, Telnet, DNS, FTP, TFTP, HTTP(S), SSH, SSL/TLS, SNMP, SMTP, RSS, PPP, Syslog, TCP, UDP, TCP/AES, UDP/AES, Telnet, SSH, SSL/TLS, TFTP, FTP, and HTTP. The built-in webserver serves static web pages and java aplets, the company says.

The XPort Pro actually isn’t the first Ethernet connector with a built-in embedded Linux microcomputer. That honor belongs to Digi’s similar product, which Digi inherited through its acquisition of Netsilicon back in 2001. Unlike Lantronix’s Linux-powered Ethernet connector, Digi’s doesn’t include a web server, however.
