JLCPCB now carrying the RP2350 in their library
« on: December 30, 2024, 05:10:57 am »
Well, at least the RP2350A (60 pin) version.  Hoping they will be carrying the RP2350B (80 pin) soon.  If you want to see them carry it, go to their site and use the chat feature to request they carry the B version.  While you are at it, ask them to also carry the RP2354 (A and B versions). These have the built in flash memory which makes for a smaller BOM.

Well, either I hallucinated the parts in their library or they sold out fast.  Now it shows both A and B versions but 0 quantities.  Estimated lead time is 11 (for B) and 12 days (for A).  Interestingly, the B (80 pin QFN) is cheaper than the A (60 pin QFN).

Did it ever show any more than 0? I remember I did look at JLCPCB not long after you posted that, and it already showed 0.
I'm assuming they have just created a new entry for this part, but they don't have any stock yet, as all other distributors so far (that I know of), as I don't think the RPi has released the official production version yet to any of them?

I placed an order for a few, just to see what would happen. They were marked as “pre-order”.

Interestingly enough, the next day I got a “partial refund” of ~$4 or so, so perhaps things are moving behind the scenes

Yes, there were several hundred in stock.  That is what prompted me to write the post.  I thought the floodgates from RPI were open.  Apparently I was mistaken.

FWIW, there have been 4 JLCPCB entries for the RP2350 parts (A, B, A vA2, B vA2) for at least 5 months.  Also, until very recently, there were no RP2350 entries in the LCSC catalog.  This is quite frustrating when there are a number of products based on the RP2350 that have been released (and are orderable).

And, there appears to be some confusion at RPI because there are hints on the RPI forum about "good reasons for the delay" but no actual info. Perhpas related to this?

[Edit]  BTW, they also have RP2354 A and B listed.  0 stock and clearly incorrect prices. I'm hoping those parts become available soon as well.

Update.  There is apparently a beta program for RP2350 between JLCPCB and RPI.  I believe you need to be in the sample program from RPI and want beta testers to follow their BOM, schematic and layout guidelines closely.  Apparently JLCPCB will review for adherence. A bit strict but I can live with that for at least the first turn of the design.  It's great that they are doing this. Very responsive to a clear need in the RP2350 community. And, I think it is great that JLCPCB and RPI are working together on more than a "here are the chips, go party" basis.

For more information contact RPI (sorry don't have the info handy).  Maybe PRI could post info about the beta program here.

I don't know how much time had elapsed between your OP and when I had a look, but probably a few hours at most, and I guarantee you they were all gone. So maybe it was a mistake on their part, or they sold them immediately (which wouldn't be surprising), although I'm not even sure they were allowed to resell them directly to customers at this point.

The situation had been discussed here: https://www.eevblog.com/forum/microcontrollers/where-to-buy-a-rp2350-chip-currently/msg5697225/#msg5697225

The sample kits (that shipped late) had only a limited number of parts. And only the bigger fish had access to much larger quantities, allowing them to sell products based on them early and in large quantities (Sparkfun, Adafruit, ...)

I don't know where they're at currently, if the situation has evolved yet or not, but it doesn't really look like it. And I don't know what incentive they would have to advertise their "beta" program, as it's obviously reserved to selected partners and they are unlikely to ever consider individuals or very small companies. As I mentioned, there were sample kits for that. If you missed them, it may now be too late to order a kit. And if you need more quantity, then you'll just have to wait. I suspect it's still a while before they'll finally release it to the public.

I got a sample kit.  And, I am in their beta program.  I'm just a little guy.

I got a sample kit as well, eventually, and I’m just a hobbyist.

My bunch of 2350B’s just turned up in my parts library at JLCPCB and they’re available for use, but subject to the above design restriction.  I’m kind of miffed about that because when I laid out the designs, the AOTA-B201610S3R3-101-T ( the “special” inductor) wasn’t even named let alone available, so I used the design off one of the commercial boards for vsupply and now I’ll have to rework that. C’est la vie.

So now I’ve just ordered a bunch of the inductors (so that I pass the QA test before assembly) which’ll take another couple of weeks to arrive but still arrive earlier than this restriction will last. They sent me a separate email asking me to be coy about when that will happen (an hour or two after the parts email) so I won’t say when that restriction expires.

Order latency was maybe 2 days for the RP2350B, I bought 30 of them and got a small (~$4) refund over the price I paid a day after ordering, so I think they’re still working out kinks. Still, feels like progress.

Thanks for the post.  Looks like they have a reel each of A and B.  Price went up, though.  I'll eat the cost of the inductor and xtal for now.  Eventually, I'll switch to lower cost components and maybe a TI LDO instead of the inductor (the LDO is half the cost of the inductor).

qty=66,000 RP2040's though. guess I will still be using that for my next production run

Yes, they now have stock but it's still in pre-order mode (11-12 days lead time). And yes, prices are double what they were supposed to be. Odd.

I also noticed they added some weird references (no stock), such as this: JIALICHUANG SMT RP2350B vA2 (C9900136556). Does anyone know what the heck that could be?
