SparkFun To Manufacture Teensy

The hash marks are the same between PJRC and Sparkfun boards. If it is morse code, it would be RU and could stand for the material being UL listed perhaps, though that seems like a bit of a stretch.

I heard that they have all the parts on-hand but they’re still ramping up production. They told me about 10 days ago that it’d possibly be another 4-6 weeks.

It seems they're back in stock, I placed an order for a bunch of T4.1 NE through sparkfun about two weeks ago as well they just shipped
 
@Paul just so you're aware:
I just got an order from SparkFun, and I think they're mixing up the lockable and non-lockable Teensys. Here's the full list of order issues. They may need some guidance from you:
1. They're not including two 3x2 headers in the Ethernet Kits. I ordered a bunch, but only a few had one header, and the rest had none. I might need some help convincing them to include two headers per kit, not one or none.
2. They're putting what looks like non-lockable Teensys in lockable bags. Unless they're not stamping them with the lock symbol? In which case, how to tell the difference?
3. They're not sealing the lockable Teensy bags with that sticker PJRC used to put on them to cover the opening.

Or... what's the best way, programmatically, to determine if a virgin Teensy 4.1 is of the lockable variety?

On the PC side, in Teensy Loader, look for the messages in Help > Verbose Information. For example:

Code: 
15:39:17.116 (loader): secure mode can not be locked: this is Standard Teensy

From code running on Teensy, you would look at the fuse settings. But I need to be very careful talking about the fuses, since PJRC signed a NDA and NXP considers the "reserved" fuses confidential info (which probably doesn't make sense on from an engineering point of view... but there's no use trying to argue over matters of policy with a mega corporation).

Thanks for that. I can tell the difference in Teensy Loader. (I need to trigger an upload because there's no "get info about this Teensy" feature in Teensy Loader. Would that feature be possible?) Now how to convince SparkFun to label them differently...

All the best to PJ & RC with "delegating" the manufacturing and sales! Hope this works out for the best for you and your team!
