Does anyone know a USB Wi-Fi dongle with a smallish form factor that is compatible with resin available for purchase/shipping in USA? (A link to amazon.com would be ideal).
Currently we do not have a recommendation for a small factor dongle. I raised recently an internal issue with updating our pages with supported WiFi devices though. I personally am planning to run more tests whenever I have time for this.
I am having a small collection of dongles here and when I am evaluating my next buy I would first investigate what chipset the dongle has. One nice place for such information available is https://wikidevi.com/. Then I would research what drivers support it on Linux. If an out-of-tree module is needed this project may help in building it: https://github.com/resin-io-playground/kernel-module-build
Please let us know your findings about the dongles you ordered.
