I ordered the PCB for version 1.4 from OSHPark on May 1st. It was sent to fab the same day, and shipped on May 4th. Today (May 13th) I found it in my mailbox. I was waiting for it eagerly, hoping it would arrive before May 17th, when I'm departing for PyCon.us -- I wanted to take the prototype with me to show it there. It actually arrived 4 days earlier than anticipated, which is great!

However, I'm still missing parts for it. The buttons I was able to scavenge from the earlier prototypes, but this new version uses a TM1650 chip for handling the buttons, and that is still on its way from China (it took the seller two weeks to ship it). You can see the empty footprint waiting for it.

Then again, I was able to verify that the display works (I was a bit afraid I broke something when moving the chip on the other side of the board).

Hopefully the chips arrive soon, or I will also receive the version 1.2 of the prototype -- that's the one with the buttons connected directly to GPIO pins, and with ghosting problems. That was also ordered on May 1st, but shipped on May 9th, so 5 days later...
