Another vote for the standard A-B USB lead here.....
There are only a couple of reasons that I can see the justification for the mini-USB connector:
- Availability of power adaptors/wall warts with a mini-USB plug output.
- No worries about a shield "shorting out" with the mini-USB jack.
Now, number 2 can be eliminated fairly easily with good board design and/or a piece of electrical tape; kinda hackish, but it works.
Number 1 does have a bit of merit, though. Maybe instead of changing out the connector, a source of wall warts could be found that have a Type-A jack? I know they exist (or existed in the past), because my USB Cybiko had such a setup (although I think its total current output was only 200mA?). So - maybe if we can find a source of such jack (with a larger current output - say 500mA), then we can have the best of both worlds, so to speak.
Maybe tonight I'll try out that Cybiko wall wart and see how well it can power my Arduino (It'll probably work OK, as long as the current needs are low)...
