(as of 2026-04-23)
After the talk on Grazer Linuxtage (media.ccc.de, youtube.com) we got many responses from people also wanting to buy this receiver. We fixed a few issues of the first revision and ordered 200pcs of Revision 2.
We expect the 200pcs to arrive in the first week of May, 2026. The cost of one complete receiver (excluding case and mechanical parts) is about 20 €.
If you want to purchase a receiver PCB, please contact us at the email liked in the Imprint/Impressum of opentrafficmap.org"
That's for a hardware receiver. It does not appear to have mobile app or API doc accompanyment or a doc on what is needed for expansion. I would imagine that there is a minimum critical mass and municipal buy-in for such devices to work. Theoretically, mobile apps would require far less barriers to start being useful.
