[PSA] B3 modules are NOT compatible with B1/B2

[dogie]

The boards connecting the individual cards to the cables have a new design which does not fit with original modules. See below pic. Additionally, the mounting screws and spacing are different on B3 modules.

*note I've just ghetto mounted the 4th B3 module for now, its not [and cant be] screwed into the case. Rotating it is the only way to get it to fit.


Shitty camera is shitty. B2 3 module with a B3 module

When you state "not compatible" you imply that they aren't electronically and/or physically compatible.  They're just not physically compatible ...

Before connecting them electronically did you check if they are electronically compatible or did you do the "close your eyes and pray" type of deal?

That was such a tard comment. Anyway, physical incompatibility is incompatible. You can't put B3 modules in a B2 unit.

Sounds like a drill press applied to the bottom panel could solve this.

Do the new modules use more, longer, and thicker screws (I hope)?

The only slot you can put a B3 in is the bottom, and then yes you'd have to drill it. You'd also have to drill new holes with the new spacings. IIRC there is one less mounting screw, same screws but with different spacings.

This is useful information, TY.

Yet, you just did!

(Thanks for sharing though.)

Thanks for the heads up.

Hmm interesting, the batch 3 (3 module) I received a few days ago has the B2 style modules.

Yes that's not a true B3 though. The unit I'm showing you IS actually a B3, but its a B2 style.

There are:
B1
B2
B3 (old B2)
True B3.

True B3 modules aren't compatible with B2/old B2.

The module is lose in the case and can't be moved. Cooling is compromised, and its at risk of getting shorted. You can only physically fit 1 module in as well, you could have 2/2.

When you will get ROI, buy a camera please.

My main phone is being replaced, this is an old N1 with a crazy ROM that breaks camera.

Whoa dogie, down boy.  That's exactly how your title reads.  It's exactly how everyone uses "incompatible" when talking about computer gear.  "Incompatible" means to me that there is no way to get it to work. 

On top of that you say you can't put them in a B2 unit, but you show a B2 unit with a B3 board in it? Wat?  You clearly "put it in", whether or not you mounted it is another question.

Mixing them would confuse the software temperature targets of the different modules too since B3 modules read 20 degrees higher due to being closer to the chip.

Would this matter?  It's possible that B3 bitstream is optimized for B3 temps (Atleast for the open sourced hardware solution).  Though wouldn't that just make the fans run faster for that 'sensor'?

From my understanding the temp sensors are aligned 1:1 with regards to the fans.  If a higher temp is read in the lower module the higher temp would make that fan go faster?  Therefore, possibly making the issue a non issue?  Just guessing and haven't checked.  This assumes the same temp sensors are being used (and based on pictures it appears the same ones are used).

Yep. In my case there are no probes on the 4th module so its scaling off the others.

1) You can only have 1 B3 module fit inside
2) It must be rotated
3) It can not be screwed in
4) It is vulnerable to being shorted
5) It receives reduced cooling
6) Case must be on its 'back'
7) Case can not be moved

It is a temporary solution to my 'pure' B3 arrives and it can live in there.
