These pots are excellent - I am using one in my build with a TPA3255 EVM and the pot
is tracking well and quite smooth.

I agree with Eric - a small PCB would be most useful.

** WARNING: untested pcb **

Here is my attempt in Eagle - someone can check if the pin order I assume
for the pot is correct or reversed as the pots are not at hand for me to check.
Feel free to change the eagle file as needed.

Hi Shaan,

Interested in 3 sets if still available. Please send total amount by PM.

Now Prasi will need to create a small PCBs so we (older guys) don’t struggle soldering on these tiny potentiometer contacts...lol

Thanks
Eric

Hi Eric.

Yes I have still a few hundred pots left. I will be getting update on all currently available shipping options for Canada next week from the PO. The only option available right now (EMS SpeedPost) is expensive and will cost 18USD! If that is okay with you then let me know via PM along with your email address. If not, please wait a few days.

Thanks.

Hi

I tried uploading your file to JCLPCB but couldn’t see an image of your pcb.

Can I have the actual size. Would be nice to be able to fit a few on a 100x100mm pcb and be able to break/separate each pcb.

Thanks
Eric

Hi Shaan

Did you get a reply from the post office regarding fees to ship to Canada?

Thanks

The size is 20mm x 36mm , so you could certainly tile quite a few into
the 100x100mm pcb separated by v-grooves - do you know how to panelize
Eagle layouts? Haven't tried it with eagle myself.

More importantly, I could not check the pinout of the pots, as they are not with me,
and I may only be able to check towards the end of the September.
The pin order may need to be reversed - will know only after I check against the real pot.
Till the pinout is verified, I would advise you not to use the posted PCB.
