Most Nanos come with the pins installed or you need to solder the pins into the Nano

Nano has 30 pins per side and sometimes the six pin header pin is included.

?

Use the below to search for like items or order from these sites as shown.

?

New Nanos usually come with the Nano port - USB cable so you can down load sketches.

?

I program my Nanos not plugged into the DDS.?

Just make sure the NANO (pins) is resting on non-conductive surface.

?

I’m sure other members have better parts sources IE ? ?K9AGE

?

I would use pre-cut 15 pin headers as I find they are a bit tricky to saw…I use a FINE tooth hobby saw.

?

The pins are segmented so small wire cutter pliers should work.

Make an effort to keep pins and headers at right angles to the Nano./ DDS PCB.

You can solder a center pin and or header and check for alignment. Then good to go-solder all. Check for solder bridges etc..

?

If you’re not sure about this procedure- note the component side and place a mark denoting the USB port for Nano insertion.

?

And finally I write the version # on a self-stick Dot? This way I know what sketch I downloaded into the Nano .? I have about 4 Nanos floating around on my desk so I try to keep from confusing myself.? Otherwise just boot the Nano and DDS will tell all.

I show and used more wires on the LCD than are needed,.,to ?lazy to make more efficient for now.

I encourage you to shop around and I like free shipping :)

I’m almost certain many BITX’ers know of better sources.

Can you point me to a source of the headers and ribbon cable you used?

I am very new to all this. I would like to try your approach for easier modularity?

Thanks

For what it's worth..I have down loaded my DDS pictures with the Nano removed.? I installed headers so I can Plug n' Play nano's as improvements come in.? Just remember the USB connection on the NANO points off the DDS as always (after you solder in the headers).

Hope this helps along with the other BITX Group help/ suggestions.

The extended LCD display is something I'm trying out.

You should be able to zoom these pictures

It is possible that the mistake only zapped the program inside the Nano
without destroying the Nano.
I would first try programming the Nano using the instructions found here:
? ??/g/BITX20/message/31491

I do recommend you download Allard's code as mentioned above.
It should work just fine without any hardware mods to the radio,
and fixes a number of issues that were in the original code shipped with the radio.
If curious, here is that original code that shipped with the radio: ?
It requires the use of an old etherkit Si5351 library, not compatible with the current library.

Perhaps I am wrong and someone will have a suggestion for an easy fix.
But I think your easiest solution is to buy a new Raduino from HFSigs.
