RasPiComm v3 missing headers
I assembled RasPiComm v3 and it all works. This should be the design for production. Sadly the new connectors for the RS-485 and RS-232 ports still need 2 (!) more weeks to deliver, I ordered them 2 weeks ago. I only have the 2-pin pluggable power header yet, and only one half (the pluggable screw-terminal also takes another 2 weeks). So the picture to the right is still missing the pluggable headers, but you get the idea of the new design.
I had to make room for the new (big) pluggable headers, so the outputs are now on 2mm pitch headers (not polulated). SPI and input are also 2mm pitch headers and also not polulated. If you need the inputs, outputs or SPI you just need to solder the headers. I think most useres wont need them, and if you do it is easy to retrofit.

I changed the I2C header from through-hole to SMD, simply because the battery holder is now below this header to avoid collision with the S2 header of the Raspberry Pi. This will probably be a male connector on the production board.
I know, what you are really interested in is the availability. Well, I already got the quote for the first batch, way off my initial calculation, but they screwed up the material costs. They now have my BOM and I’m waiting for another quote. So I’m still on it and hoping that I can place the order in one or two weeks.
