Prototype smart card chips in DIL-40 case have arrived

Finally, the first samples of the smart card chip (for the Osmocom CardOS project) have arrived. As opposed to the final smart cards, this one has been packaged in a DIL case instead of the usual thin credit-card sized plastic. The reason for this is quite simple: This way lots of I/O pins for debugging as well as JTAG can be accessible during COS development.

Here you can see the first incarnation of a veroboard connected to an adapter pcb inside an Omnikey smart card reader:

After confirming it worked, I soldered the wires directly to the adapter PCB, as can be seen here:

There is already a real PCB design that is currently manufactured, i.e. in a week or so there will be a picture of a clean, professionally-produced/etched PCB with all of the prototype pins exported.

In terms of the COS, I haven't done much more work than compared to the last posting, mainly due to a large number of other projects. But we will get there...
