I picked up a MINIENC1 a month ago to try it out. It works just as well as the ENC1V2 for what Channels users would be using it for.
Just make sure you upgrade the firmware as the shipping firmware has a bug that locks it to 30fps.
It’s a tiny thing:
Sharing some info: I have noticed with the ENC5V2 and the MINIENC1 that the AVBR encoding mode doesn’t work as well as it does with the ENC1V2. The bitrate often drops way too low during scene transitions which results in a few seconds of really blocky video. Based on this experience my recommendation now is to stick with VBR or CBR mode.

And sharing some more info:
The Onn 4k Pro streaming devices are a good combo with most of the LinkPi devices (not the MINIENC) because they are also powered by 12v DC (5.5mm connector).
A power supply like this:

combined with a simple splitter

can power the whole setup without any additional adapters.
