Beitian BN-880 (I’ve bought mine from Banggood) is an excellent, cheap and accurate Ublox NEO-M8N GPS module. I’m using it for last few months and I’m very happy with it. But is has one serious flaw: there are no cases/enclosures for it. So, in most applications it is naked. I’ve decided to fix that and designed 3D printed Beitian BN-880 case.
Case can be dowloaded from Thingverse
