H5 A5 BOM (or lack of)
Re: H5 A5 BOM (or lack of)
@exxos | @Icky, getting ready to shoot the juice to the first H5. First though I have a couple of questions. First what is CN9 for? Since its looks to be a 3.3 volt connection in the 3.3 volt subsystem I'm not populating it. Sj2 looks to be a solder short but its all ready shorted so I'm disregarding it. Lastly j2.. guessing an audio connection. If any of these are required let me know. Thx...

If they are not listed in the jumper thread then you should do nothing and ignore them for now..

Re: H5 A5 BOM (or lack of)
Hi, after seeing that B1 rev is coming, I decided to try to get my A3 up before the first B1 arrives, I’m halfway through now and was wondering about Y1 as this crystal is not part of the BOM but is clearly visible on the H5 silkscreen, and it seems to be required by the MFP.
I got one from donor machine anyway, but wanted to know before soldering it.

@olivier.jan yes its the 2ish mhz one that's used by the MFP so a donor from an existing board is perfect.
If it ain't broke, test it to Destruction.

I can't remember but the battery(holder) is CR1220, right?
