I must admit, I have often wondered if anyone will create a mains-powered supply with +5V and +3.3V output. Designers would still need the occasional 2.4 and 1.8V regulators but overall design should be simpler. Board costs less, supply costs more - may include features like shutdown under software (shutdown -h now) Could be used with other dev boards : Arduino, Pi, etc. Add a HDD compatible connector for future expansion, or the Cubieboard which already has SATA. Would you buy such a dev board / supply combination? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

It stuns me anyone would plug in power without verifying the polarity is correct.

This is something *anyone* should check. Always. But of course it doesnt happen 100% of the time. Much easier than waiting x amount of time for the new one to arrive, not to mention now you're out ~$60 US.

Think economics and not technical. Since there were very few returns because of reverse polarity, it isn¹t cost effective to add the protection to each board. For example, circuitco has shipped 177,000 BBB multiplied by $10 protection is $1,770,000. Less than 20 returned because of reverse polarity at $55 each is $1,100. The solution is obvious.

Re: [beagleboard] Re: RIP Never Used BBB
I wasn't saying make it bullet proof, just some simple goof proofs. Like on the 5v plug, that kind of thing. I get the whole cost thing and by and large agree. I'm sure to try and cover everything would cost a bit, Not sure why anyone would be putting 220v to the 5v plug, but i could understand reverse polarity on the 5v plug. Not sure it needs to be gone to the extreme. How hard/costly is it to fix something like reverse polarity or blown gpio? if repairs are easy enough, perhaps protection isn't worth it.

Re: [beagleboard] Re: RIP Never Used BBB
But, our goal was as low a price as we can get. Adding a protection against all the things that could happen means it would have to be water poof and withstand 220 VAC on the input. That is more than $10 to $12. Reading the manual and the wiki is free. Gerald On Wed, Jul 30, 2014 at 2:50 PM, wrote: > I think I would of paid 10 - 12 extra bux for a BBB that had some > protection.
