Alas, I haven’t had a whisper. And while I am grateful to you for volunteering to lend one of yours, I agree that Canuckistani postal rates are prohibitively expensive. I don’t know the detailed fee schedule but it’d likely be more expensive even than buying one from a US source on Fleabay and putting my address as the destination.
One thing I can say is that any 68882 at all will work — the FN-marked ones may be a problem to resell in a finished product due to RoHS rules, but that hardly matters for a prototype.
