I normally would just build my own and etch my own boards. I gave that up years ago and don't have the chemicals or the drafting light table any more. The hard part is done for you.

Back in the day I would build it, but now I would forget why I built this thing.

Interesting how it uses 6.14V Zeners to protect Inputs - not like that thing needs it...
