assembling a few more OtterCam-s3‘s today.

it boots!!! Soldering the BGA was much more trivial than anticipated, the QFN in the lower left corner was certainly worse…
next up: I think I will do at least a second board and uh, the sensor board, which contains the 'spicy BGA', the image sensor. It’s in theory as easy to solder, but it’s also a rather fragile part, one entire face must not be touched too much

this is how the image sensors were delivered. How does that make you feel?

@janamarie does it make alignment easier?
@atna very!
a press fit always is easier -

assembling a few more OtterCam-s3‘s today. Haven’t soldered a BGA in a while, so wish me luck
this shouldn’t be too hard though, it’s a pretty coarse pitch and my technique should still work pretty well
@janamarie do you like that RJ45 socket? I’ve been looking for an SMD vertical one recently, but was put off by the all plastic ones (solely based on vibes)
(eventually settled for a mostly SMD metal option)

@ErinRose no, not really, but I also don't dislike it. I wouldn't reuse it

this board is somewhat of a nightmare fuel to networks people, please note the ethernet decoupling.. ~ :3c
@janamarie did… did you use capacitive coupling for ethernet?!

@janamarie you deserve to get your sensors delivered to you like that <.<

@slyka @janamarie it certainly does work

I got this board assembled from JLCPCB, but a lot of components are still missing. This is mostly due to this board being one of the very early boards running through their PCBA process! I actually wrote on their blog about how the PCBA process works at the time, they allowed me to test it very early :3
@janamarie o.0 wdym test early?… i've used their pcba like 4 years ago???? 0w0
