Welcome to the WISP5 Wiki
What is the WISP?
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.
A Few Guidelines
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 WISP5 are open source: WISP5 Firmware and Hardware
Got questions, or running into trouble? Got ideas for future WISP versions? Please email us at mailwisp at gmail dot com
The WISP5 is the latest iteration of the WISP. For resources related to the earlier WISP versions, see WISP 4.1, WISP 4.0
Looking for the NFC based WISP? The NFC-WISP interfaces with smartphone readers and more! See the NFC-WISP wiki
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.
