I lied!

After receiving some more enquiries about FlipFlop boards I have just placed an order for an extra ten. They will take a couple of weeks to be delivered to me and these really will be the last ones.

At this time I have five SE and six FF boards available.

Hi Felipe, there seems to be a steady trickle of interest so I expect them all to go; if you actually need some it may be worth getting them anyway before they do all go.

"Power - connect DSD board pin 1 to your 5V Amanero power supply"

My Amanero operates with 3.3V, is enough for the mute trigger?

I don't think so. You can get lower voltage versions of the relay though;

http://www.farnell.com/datasheets/1683361.pdf

but then they will pull more current from the supply which might have other implications for the circuit? Maybe it would be possible to drive a 3V relay coil direct from pin 7 - don't know how much current it can deliver?

The power supply doesn't need to be anything special though so a basic 7805 supply should do if you want to run it at 5V.

I've had a couple of chaps asking about schematics and BOMs so here's a link;

The PCBs have most of the part numbers/values printed on the boards, I think you just need to sort out your own rf, cf and rLED values.
