Where is the driver info? The vendor's page seems devoid of configuration information.

It can be tricky. Even with their information, it's only easy if you revert back to one of their supported kernel versions. It works well when properly installed, but in my case I did not want to go back to a prior kernel so I downloaded the kernel code and cross compiled the drivers on my linux system. https://github.com/respeaker/seeed-voicecard There is information on the Seeed wiki

I downloaded the seeed-voicecard files but the mic still isn't showing up (arecord -l and aplay -l). how can i get the rpi 3 b+ to recognize the mic?

You might need to clone the git repository and run the installer script, which will recompile the kernel if it's not working on the default kernel. This is what I had to do, and then everything worked for me.

Does the 3.5mm Jack support microphone in as well as speaker out?

The 3.5mm Jack only supports speaker out. But the MIC-L and MIC-R support microphone in.

Does it need separate power it works with the Raspberry pi power itself?

Pi powered. No external required.

microSDカードをクラッシュさせる

VolumioのDACとして使えるか試すため購入。RaspberryPi ZeroWにVolumioをインストール、本製品を接続したのだが、本体の電源LEDが点灯せず起動しなくなってしまう。本品を取り外して別のmicroSDカードに交換すると起動するので、microSDカードが壊れてしまったようだ。自分のオペミスかと思い、別のmicroSDで再度試みたが同じ結果になった。どうやら物理的にmicroSDカードを破壊してしまうものと思われる。RaspberryPi ZeroWは未サポートとなっているが、物理的に破壊するのはどうか。個体差かも知れないが、少なくとも私が入手できたもの粗悪品である。もう買わない。
