I have one spare Input board, bare PCB only, (plus Raspberry connection PCB) and one Switch board, bare PCB only, as well as the surface mount connector for balanced build, which I would be willing to sell for 25€ plus shipping (from Germany).
No answer 🙁
Have a look

Meldano, I sent you the money on 12/3/2017. In error, I didn't include the small PayPal fee. I resent the required money today.

So, Meldano has sold to someone else.
I'm therefore still looking to buy these input boards.

Have one spare including the smd components soldered on. One input and one switch board. Rev 1.1. Never used.
Same price as the rest? 25€ + shipping is that fair?
Picture soon.

What's the most preferable setup in terms of feeding power. I've got a teroidal transformer with 2 12v outputs and a single TPS7A4700 regulator so I could drive the dam directly or can I just feed 7.5v into the input board and power my rpi and the dam in one go?
The input board doesn't power the Dam 1021. It just powers the input board and the raspberry pi as long as the pi doesn't draw too much power. The Dam 1021 requires a dual rail supply.
Hi WCWC, thanks for the info. I'm afraid I bought all these parts 2 years ago and they've been laying in a box since then but I'm hoping to make some progress this week on it.
Because I'm a novice at this stuff I was going to start out by just buying a multi voltage output psu like this :-

before I even think about using the toroidal transformer. (https://sklep.toroidy.pl/en_US/p/TT...grade-transformer-TSAS20VA-voltage-to-50V/373)
From the looks of the dam manual I should be able to just use a standard 12v dc adapter to power that.
What did you mean by dual rail?

It seems that the soekris.eu site needs some updating.. I can no longer find the manual for the 1021 and the spec sheet that does exist is kind of misleading, stating as power requirement this: "Power input 7-8V AC or +-7-15V DC max 5W".
This seems to imply that a single secondary transformer is required which is not accurate. The "+-7-15V DC" is accurate though.
The 1021 requires a dual secondary power transformer supplying 7-8VAC (not more than that!) or a bipolar DC power supply providing +/- 7-15VDC.
If I were you I'd go with a bipolar DC power supply providing about +/-9VDC.

The downloads are not on the same site as purchases for some reason. Here is a link to the download page.

Hi DimDim,
I'm afraid I don't know what a bi-polar power supply is. I know very little about electronics which is why I just want to get this project started with 2 cheap DC power supplies that I can buy in any shop.
Working with mains AC and that toroidal is project 2. Project 1 is just getting it to switch on.
