There several ways to interface an "normal" Arduino to 3.3V peripherals.
why didn't they use the PDIP-Version of the chip (which can be replaced in case of an "accident")
It's a square Lilypad and has a lot of unused real estate, it's a big but less expensive alternative to the stamp, maybe. It seems a bit rushed and the description improvised, I wonder why they are in such a hurry to get it out there, particularly since they appear to have no stock available.I noticed that they're almost sold out of Lilypad's, so I'm wondering if they plan on selling both, or just their square version.
We're actually sucking in the connectors and getting them back on 0.1" grid to please the Arduino team and to avoid confusion with user who have 5V shields.-Nathan
