The Propeller microcontroller s multicore architecture and the W5100 s hardware Ethernet stack allow a new level of parallelism and data throughput for robust and reliable embedded network applications. The Spinneret Web Server may be smallat less than 1 by 4 inchesbut it is a feature packed development platform. The built-in MicroSD card socket and real-time clock allow ample room for time-stamped file and data storage, and the oversized EEPROM can store non-volatile data for use when there is no MicroSD card present. As an open-source hardware design, all design filesincluding layout, schematics, and firmwareare available under licenses that allow free distribution and reuse. This means that the Spinneret Web Server s design can be incorporated into new applications royalty free and without a non-disclosure agreement.

Spinneret Web Server ( 32203) v1.0 12/17/2010 Page 1 of 7Synopsis The Spinneret Web Server is an Ethernet-based development board for the Propeller microcontroller. Web page content, files, and logs can be stored on a MicroSD card. The serial EEPROM has 32 KB for storing a Propeller program and 32 KB for non-volatile data storage, independent of the MicroSD card. There is a real-time clock controller for timestamping files and events and a backup capacitor that will keep the clock running through extended power outages. There is a serial programming header and there are two auxiliary I/O connections: one is a header for level-shifted open-collector communications over a three- pin data/power/ground cable, and the second is a 12-pin socket for direct 3.3 volt I/O connections. There are eight status LEDs on the PCB, two of which are repeated on the Ethernet jack. One of the status LEDs is user controllable and shares an I/O pin with a button that can be read under user control. A second button resets the Propeller to reload any firmware from the EEPROM. Open-source hardware The Spinneret Web Server is an open-source hardware design that is well suited for use as a reference design, built into a custom product, or used as a stand-alone board containing a custom firmware application. All design files are available under various open-source licenses, as included with each file. Parallax provides a Spinneret Web Server forum, available from
