Welcome to the WISP 5 Wiki!

This project is supported in part by NSF Grant CNS-1305072, entitled "CI-ADDO-EN: Infrastructure for the RF-Powered Computing Community." Additional support from NSF Grant EEC-1028725, Intel Corporation, Disney Corporation, and the Google Faculty Research Awards program.


The Wireless Identification and Sensing Platform (WISP) is an open source and fully hackable battery-free platform for experimentation with low power sensing, computation, and communication. This wiki is a place for users and developers of the WISP to compile resources related to the WISP, to share knowledge, and to collaborate on large scale projects.

  • Are you interested in working with the WISP 5? Please send an email to mailwisp@gmail.com to request information about the availability of pre-built WISP 5 hardware.

  • Check out the wiki sections in the navigation panel. First time users should look at the Getting Started section and also read through the FAQ.

  • Source code and design files for the WISP 5 are open source: WISP 5 Firmware, WISP 5 Hardware.

  • Got questions, or running into trouble? Got ideas for future WISP versions? Please post questions and comments to the "Discussion" page.

  • Contribute to the WISP5 wiki! Request membership using the "Members" bar on the side of the page.

  • The WISP5 is the latest iteration of the WISP. For resources related to earlier WISP versions, see wisp.wikispaces.com.

  • Looking for an NFC based WISP? The NFC-WISP interfaces with smartphone readers and more! See the new nfc-wisp wiki to learn more!
