Hello,
replied on PM to highpuff.
I wish to add two words about this device.
I hope soon i will release the draw of a two layer version of this PCB, but it will take time, because the layout of the tracks need to be newly draw: the pins used by this new design will be aligned in rows and not alone and sparse like you see on this device for sale, otherwise will be impossible to solder the pins towards vertical and then will be hard to put this adapter in place.
What you see on this sale, has sparse pins, because to obtain this design in a single side board, just a choose of sparse pins allow to obtain the final result that you see in this pictures.
The flat pins, that are flexible, allow a very good handling to insert it in place, but this pins are not on the market, they are made by me from other parts.
If i release the new draw, every person can build his own unit, and need to find all the parts needed to build it, in other words, you will find rows of pins (round or square of section), and only in rows you can solder this pins correctly!
What is here for sale, is made manually, tested for a couple of days, and then packed. The parts are not all the same and can be that some PCB are printed not so good (the tracks can be not so precious, but they are not visible, when the device is mounted), but, if it is here, the device is reliable and protected against oxidation.
The difference of the cost is just the cost of the programmable device and the time spent to program it: you do not pay for the content, that is freely downloadable here on Amibay!
The cost of this device is 40 Eur, with the logic, less without the logic: in this case, 30 Eur.
Regards
Stefano
