Welcome to the WISP 5 Wiki!

This project is supported in part by NSF Grants CNS-1823148 (“CRI:CI:SUSTAIN: Next-Generation, Sustainable Infrastructure for the RF-Powered Computing Community”),CNS-1305072 (“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.

Coming soon:

  • WISPCam 1.0
  • Ambient Backscatter WISP
  • Software Defined Reader

Thanks to JaeMin Shin and everyone in the Computer Network Lab at South Korea's Sungkyunkwan University for their contribution of a version of the WISP code that can operate with the Asian version of Impinj Speedway R420 readers, the R420-GX2!! Find the new WISP5 firmware repository branch here.

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 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.
  • 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.

**New features in version 5.0/5.1:**

  • New! Compatibility with Impinj R420 readers sold in Asia (R420-GX2). See the 436kHz branch of the wisp5 firmware repository to get your WISPs talking to readers not sold in the USA.
  • Energy-optimized firmware stack with support for FM0 modulation and simpler application interface.
  • Read and Write command support out of the box.
  • MSP430FR5969 microcontroller with FRAM non-volatile memory for ultra low energy data storage and retrieval. * ADXL362 accelerometer with ridiculously low power consumption.
