Nearly everybody in a shared workplace wears a plastic identification badge and an RFID-based entry card. And conferences notoriously give attendees one-time use paper-based badges. As a reprogrammable answer, networking tools firm Eurolan has launched a reference platform that mixes these capabilities into an digital choice. GGtag is an ePaper badge with programmable RFID. And it may be programmed with a cellular gadget through an online app and sound!
GGtag’s primary function is the three.52″ ePaper show pushed by an RP2040 microcontroller. A second microcontroller, a Microchip ATtiny85, emulates RFID tags utilizing a firmware referred to as avrfid. A single coin cell battery, or USB, powers your complete badge. This mixture of options makes GGTag ideally suited for shared workspaces and even as a reusable convention badge.
There are two methods to program it. The primary is simple: it’s through USB. An alternate methodology, nonetheless, makes use of a PDM microphone for audio-based programming.
GGtag makes use of a library referred to as ggwave to ship knowledge through sound. It’s an FSK-based protocol with transmission speeds as much as 16 bytes per second whereas utilizing error correction codes. One benefit of this methodology is which you could program a number of GGTags concurrently.
Mario Instance (through ggtag.io software)
A web-based interface lets you design the e-paper badge with textual content, icons, and pictures. Then you should use it to program a GGtag with both methodology. Nearly any cellular gadget will be an audio programmer by taking part in the encoded sound stream. For USB/serial programming, your internet browser should help the Internet Serial API (comparable to Chrome on desktop and Android.)
The GGtag design recordsdata are open supply and obtainable in a GitHub repository. It has the schematic as a PDF, PCB as gerbers, and several other demo badges. Quickly documentation can even be there, however at the moment, solely a top level view is accessible.
Eurolan has a Crowd Provide marketing campaign for GGtag within the preliminary stage. Go to that web page to affix a mailing record to know when the marketing campaign goes stay.
