The pinout is linked to in the first post. Basically Vout = max(Vin, Vbatt) (with some threshold effects though) ; /RST OUT is 0 if Vcc < 4.2V or /MR is down ; /PFO is down if PFI < 4V or so. I've been busy with other stuff, I need to finish the test gear then hopefully I can get some shipped.

Well it allows replacing broken chips (they are close to caps usually) with known good chips because they are new chips still in production, not some "new old stock" that possibly got de-soldered from a battery-bombed logic board that might work or not for who knows how long.

I'll probably sell a few batches first but yeah.

Thanks!

Schedule has been published!

And it's actually not that hard to solder, just needs some flux. Seems to work fine. If I use RoHS solder for the IC it should be even quite easy to remove it in one piece if needed.

Oh dear, now I know what to do if I'm bored :)

I have so many other stuff to do that I couldn't help but add support for hollow versions with Unicode Art for the angled corners.

Oops, looks like I zapped one value in the cylinder args somewhere and it made a cone, fixed. I added a margin slider. Need to go back home to push it though. Edit: fixes pushed.

Seems to work in this LC-III…

I usually add margins to the models, how much did you add?

I saw @max1zzz had a try at OpenSCAD, to generate PGA sockets, so I helped and cleaned up the code, made it more parametric, so we can now 3D-print sockets for all those… The code is here.

I received the PCBs and *finally* some chips, after a 3rd order (1st never shipped, 2nd never arrived…). Looks promising:

If only my ISP would accept the account validation mail from PCBWay…

I got a routed PCB, but so tiny it'd probably wouldn't be accepted by fabs… luckily it seems possible to do your own cuts for castellated PCBs, which means panelizing them manually would make them larger and probably easier to pass the validation. I should try that soon.

Been sidetracked by the companion chip (0120), which seemed easier to tackle first.

I've been distracted from EGRET woes by that small chip next to it… I've since figured out the pinout and characteristics, and found a potential candidate for replacement. But of course it doesn't have the same pinout, and of course it's also SOIC-8, because the smaller TSSOP version is...

If the legs are long enough, maybe a 1.2mm interposer PCB might be enough? You can check with a piece of cardboard, make holes to get the pins through, and see if they go down to the other face of the logic board. It will be a bit more fragile, but it should work.
