Many thanks Alex.
I confirm my order and will send you the money + Paypal Fees as soon as you ask for payment.
Thanks again for a lot of hard work.
Alex, Please allow for postage to the UK (Scotland). Thanks
Boards arrived
Boards arrived today as expected - see photos.
Bare boards can be shipped right now, so I will be sending you PMs with payment instructions later today.
I am still waiting for the SMT parts, so the soldered boards have to wait a few days more.

You can use instead relays with the same footprint from other manufacturers, such as Omron G6K-2P-Y or Panasonic AGQ20T. Part numbers should be:The 16-step volume control requires IM06TS relays
IM06TS - G6K-2P-Y-DC12 - AGQ20T12 (for 16-step 12V)
IM07TS - G6K-2P-Y-DC24 - AGQ20T24 (for 16-step 24V)
If substituting relays for the 64-step board, keep in mind that PCF8574AT has limiting current value of 25mA per relay and 100mA in total. It drives six relays, so the rated coil current per relay should not exceed 100/6 = 16mA, and therefore the coil resistance must be upwards of 300ohm. IM23TS with its "ultra high sensitive" coil works, but G6K-2P-Y or AGQ20T would have the potential to exceed the PCF8574AT's specifications.
Yes, the diodes are soldered on the back. Note they are not really necessary for the 64-step board, as PCF8574AT has them built in, but I soldered them anyway.did your SMT soldering include diodes D1-D4 on the back of the boards?
