IC22S Arduinoized?

[VK3ZYZ]

Install 2.54MM JST connectors under the PCB as shown. NOTE: The orientation as it is reversed WRT the silk screen on top. Another fix for #3 version of the PCB
Originally I intended to have right angle connectors mounted on top but this way works ok.

And the wires may need to be swapped around to have the colours matching as below.

Here is a closeup of the top of the PCB. (before it was cleaned).

I may do a #3 PCB...

This will allow the old diode matrix connector or a straight one to be used.
Also, an alternate mount for the C3 electro as it needs to be thin.
Finally, this has A6 and A7 connection points.

Here is an instruction sheet for the SMT board to be installed in an IC22S.
The .odf file is about 4MB but the .pdf is almost 15MB!!! Too big to post.
I do not know why the file gets inflated so much.

Here is the PDF, it's only 1.9 MB.

I just loaded it in Libre Office and exported as pdf. It's about half the size of the odt file.

I'm thinking I might re-arduinoize my IC22S, and get the latest mods.

Thanks ray.
I "printed" it as a .pdf, forgetting that I could just export i!
Do you want the SMT boards?

 

[VK3YNV]

Yes, save a set of the SMT boards for me, but supply all the others who want kits first, I'm in no hurry. The one I've got is working just fine, but the CTCSS addon would be good to have.

 

[VK3ZYZ]

The original board you have has the CTCSS built in already. The new SMT board adds a couple of analog inputs.

I am still plodding along, trying to load and save settings to EEPROM but it is not working as yet.
The code IC22S_20240401nm.zip is the latest version but without any memory stuff.

Here is the latest circuit....

One of my IC22S sets has a crook PLL board so I grew te Arduino Nano VFO into it.
(I had a previous post about this but it looks like I accidentally deleted it).

A handy mod for when working on sets is to add a connector to the speaker lead.
