Thinking of fitting a Blackmagic Decklink Microrecorder onto the mini-PCIe slot of a Single Board Computer to have a portable RTMP streaming unit.

Unfortunately the specs on the site dont mention how many audio channels it can take in. The other Decklinks that fit into PCIe slots take in 8-16 channels of audio.

Does anyone know how many channels this particular unit can take in? Hoping it's 8 or even better, 16 channels. That would be ideal for my usecase.

There's also the Decklink SDI micro that goes into an M2 slot. There's no information there either about audio. Anyone with experience with either of these units?

Thanks!
