This week I happened to be in Portland for the Embedded Linux conference so I had a chance to pick up boards directly from OSH Park.

Here is a picture of a few of the boards taken at the OSH Park home office:

Here are a few more pictures now that I am back home.

As you can see some of these boards are still partially connected. The "mouse bite" connections are required to combine them with several other PCBs in a large panel. I got to see a sample panel and the CNC routing is quite elaborate.

The silkscreen is impressively accurate. This is done using a special process that essentially adds another layer of soldermask of a different color.

As you can see the boards fit the tins as expected. Probably going to be a bit tricky to get the holes in the tins for the USB and MicroSD connectors.

Overall a very nice board. Thanks OSH park!

If you want a chance to see a few of these bare PCBs in person (and happen to be going), I will be at Scale15x in a Pasadena next week. Catch them at the exhibition booth.

did you order your stencil yet?

Not yet Dave. Any last minute recommendations? Besides not soldering BGAs in a toaster oven at home. :)

No banana for scale though :( Good luck with soldering that - I tried an I2S microphone the other day... with 5 pins of that size, I wouldn't dare soldering that BGA chip :) nice work.

Sorry out of bananas. I will post the next best thing. A lineup of it, the beaglebone black and C.H.I.P.
