These are the remaining boards for the original HPSDR radio using the Atlas backplane.  For further information, see HPSDR Documentation.

This is old inventory. We’re trying to clear it out and send it to a good home.

Here’s the deal – You can have the boards for free. You still have to pay shipping. Of course, I’ll use the smallest size box I can to keep the shipping costs to a minimum. I want to give everyone a chance to snag some of these boards, so I want to limit any order to 5 max of any particular board. That’s per order. No reason not to grab up to 5 each of all of the boards, though. This limit doesn’t apply to Janus boards, the GT+ V2.2 GPS Receivers, the GPS Antennas, or LPU Parts. We’ve got a bunch of them, so take all you want.
