TinyPilot Voyager comparison
First the good news: Voyager 1 (V1) and Voyager 2 (V2) use the same software, and (nearly) the same Hardware. So as Voyager 1 user you will benefit from all software updates as the Voyager 2 users. The reason is easy: The technical base is on both systems a Raspberry Pi4 that gets the video data from the same HDMI2CSV converter. So both, Voyager 1 and Voyager 2 have the same hardware in the major technical components.
But what is different? Voyager 1 uses an external power and data supply, while the power supply of the Voyager 2 is internal. This leads so a little bigger case for the Voyager 2, and some more cable organisation for the Voyager 1. But on the other hand, the Voyager 1 is more flexible with the cabeling in my opinion. So at the end, it depends on you, what you would prefer.
In Voyager 2 the USB-c, the audio, and two micro USB adapter are now internal, and cannot be used. But you never needed them for TinyPilot using as a KVM. But have a look on your own, what is different:
