DXDUSB Next Version with Custom PC Board – UPDATED

After using some DXDUSB prototypes with DX Doubler SO2R boxes for several months, I finally got around to completing the PC Board layout for the next version. This one will add some power conditioning and choice of operation from +5 or +12 VDC. It also should be able to survive use in a Mobile environment where the voltage can go well above 12 VDC.

This should be a more reliable DXDUSB. For those who have asked about the availability, this version should be available in early November. Watch for updates as I assemble and test these boards. They should arrive around October 20th.

The board is a just under 2-inches on each side. It should fit inside a small enclosure similar to a dual-port Ethernet box. You are only seeing the wiring on one side of the board, so there is much more to it than what you see here.

I have also been considering a version that could be mounted inside the DX Doubler box. The only problem with that is that I would need to remove the DB-25 (Parallel Port) connector on the DX Doubler’s circuit board inside the enclosure. I have been considering the possibility of installing this board in place of the parallel port connector on the X Doubler product, since nearly nobody wants parallel port devices these days. Makes sense, since you can hardly find a new computer with a parallel port and the add-on boards I have seen do not seem to work well at all.

UPDATE – I have now built a few of these and they seem to work great electrically. Unfortunately, my Mechanical design skills are a bit lacking and my mounting holes do not align well with the small chassis I hoped to use. Another (hopefully final) version of the Board is coming, that will hopefully eliminate these issues. The current prototypes are strung together with cable ties inside.

I now have a few working prototypes and the only remaining challenge, electrically, is the 12-volt power version. I want to have a 12-volt version for use in shacks and in Mobile/RV equipment. The voltage regulator on the Arduino Pro Mini continues to worry me, and I at this point, I will say the USB-power option seems to be the best. That is what I am using in the shack. I also have a USB hub in my Mobile setup. You can’t beat that nice, stable 5-v supply.
