The SBC68EC is a Single Board Computer (SBC) with a 10Mbs Ethernet, Network-Bootloader, RS232-interface, IēC bus, 12 analog inputs, 32 digital I/O-ports, free TCP/IP Stack, PIC18F6680 and web based configuration. The board is fully assembled and tested with a PIC18F6680 controller and 24LC512 EEPROM. The SBC module can be connected with every 10/100Mbit/s Ethernet network. The PIC18F6680 controller is already pre-programmed with the free Modtronix SBC68EC Webserver The 24C512 EEPROM can save websites. With a FTP client (or rather with a terminal tool like Hyperterminal) you can replace the Demo website with your own one. There is no need for a new programming of the firmware and a external programmer.

The user can add "special tags" to the HTML websites, which can be replaced through values from external input pins or external analog inputs. All inputs, outputs and analog inputs of the Ethernet module can be configurated. The website will be created with a conventional text editor and loaded with a FTP client to the webserver about a serial cable. The SBC features a pre-programmed bootloader. The Modtronix network bootloader allows Firmware updates about network and internet.

The serial RS232 port of the Ethernet SBC can used for the configuration and for debugging of the webserver. All configurations made about the serial RS232 port, you can make also about the website of the server.

The whole source code of the webserver can be downloaded for free. The webserver uses a part of the free TCP/IP stack software from Microchip (programmed in C) and can be edited with the HiTech or Microchip MPLAB C18 compiler. A free student version of the Microchip MPLAB C18 compiler is available.

Typical applications

  • HTTP Web servers
  • Mail clients
  • Ethernet to RS232 interfaces
  • Ethernet to RS485 interfaces
  • I/O controls
  • Protocol Bridge applications
  • Ethernet to USART, CAN, I2C, SPI etc.


  • equipped with a PIC18F6680 controller, 24C512 EEPROM and Modtronix SBC68EC webserver with bootloader
  • 64 kBytes FLASH, 3840 Bytes SRAM and 64 kBytes EEPROM. The webserver uses fewer than the half of the existent FLASH and SRAM and ca. 25% of the available EEPROM memory, extendable for a 8-pin SPI FRAM chip (e.g. 32 kBytes FM25256 Chip) on the bottom side of the board.
  • supports HTTP compression
  • UDP with more than 1.2 MBit per second with the standard Modtronix TCP/IP-Stack
  • 32 programable I/O pins
  • 12 programable analog inputs with 10-bit resolution
  • red programable LED
  • green LED "connection"
  • yellow LED "send/receive"
  • RS232 interface about a 3-pin connector (compatible cable CAB3S6FT)
  • Micro Match connector strip for connection of IēC devices like the LCD2S serial display
  • modular design, extendable with extension modules
  • regular 2.1mm jack plug for power supply (7-35VDC)
  • +/- 15kV ESD protection
  • ICSP (In Circuit Serial Programming) connector
  • free Modtronix TCP/IP Stack with the following features: MAC, IP, ARP, ICMP, TCP, UDP, HTTP, FTP, DHCP, IP Gleaning, MPFS
  • supports TCP and UDP
  • RTOS independent, full TCP state machine
  • free registered MAC address included
The "daughter" connectors can used for a modular extension of the Single Board Computers. Numerous extensions and functions are possible.
