Difference Metro 328 PID50 vs Metro 328 PID2488

by RFster on Thu Oct 18, 2018 7:07 pm

I am about to order a couple Metro 328 boards, but I am confused: I have an older one (PID50) which is fully assembled with SMD headers.
The PID2488 description states fully assembled with through hole headers. The PID50 description claims that it is also fully assembled with through hole headers...
So what's the difference? (why two PID's if they both use through hole headers??).
The SMD header version is nice because the backside is clean, but the headers are quite flexible sideways. I would like to get the "through hole headers" version, but fully assembled.
So... which PID should I order??
Thank you in advance.

ps: I LOVE this board BTW... GO ADAFRUIT!

Historically, PID 50 was the Arduino-branded Arduino Uno. It's one of the first SKUs ever to go in the shop, and there are tons of existing links to that page.

Then came the trademark/ownership kerfuffle, during which time we developed the Metro as our in-house equivalent if it turned out to be necessary. We also added some features we found desirable, like easy conversion to 3.3V. We had to release that with a different SKU because everything in the provisioning was different.

Today, the Metro 328 is what we sell in place of the Arduino-branded board. That might change in the future, and we want to keep the historical SKU available in case we need it again.

Thank you Mike.
So basically if I get it, both PID50 and PID2488 are the same product; is this correct?
Lastly did you guy do away with the SMD headers? (if not, please let me know which PID has the through hole headers already soldered).
Thank you for the clarification!
Cheerio!

Right now, yes.

All versions of the Metro 328 use through-hole headers. I don't remember off the top of my head whether we used SMT headers before getting the selective soldering machine up and running, but the headers are through-hole now.

This is the only version that doesn't have headers soldered into the board:

OK, Thank you Mike.
A number of units with SMD headers have been produced for period of time (I have one sitting on my desk), but they have probably been phased out by now.
All is clear now and I know what PID to order.
Thank you again!
