Updated Plug Shield

The updated Plug Shield has come in, here pre-assembled and with all the headers soldered on:

This fixes the problem with D9, and adds one extra feature: there is now a pull-up for the IRQ line, with a solder jumper to connect it to D3. See the label “JD3” at the middle right in the above picture. This makes the IRQ pin on the port headers compatible with the JeeNodes when an IRQ pin is needed.

This shield is still called “v1” due to an oversight, but that should not be too much of a problem because only 3 prototypes have been sent out. If you got such an “old” prototype shield and want the final one, get in touch and I’ll send it (pcb-only).

On a related note, the Memory Plug has also been updated (to “v2”, correctly this time). This fixes an addressing limitation with 128 Kbyte EEPROMs.

Onwards!
