content: https://www.kickstarter.com/projects/rabidprototypes/neutrino-the-tiny-32-bit-arduino-zero-compatibleHey guys,This is my Kickstarter campaign. I've been waiting a year for the Zero to come out so I could design a board like this and start using it in my own projects, and when it was released unexpectedly a few weeks ago I knew I'd have to act fast if I wanted to be first to market with it.Thankfully a month earlier I'd learned of a new PCB manufacturer called MacroFab, and they were able to order the PCBs and assemble a prototype for me quickly. I'll be ordering a second from them soon with the final layout; I moved a few parts around to improve the routing.The design will be open source.I just got the pinout diagram done last night:

content: Very nice!Does it support a debugger? Is it mbed.org compatible?

content: It supports the Atmel ICE for debugging.As for mbed, I'm not familiar with it, and I can't for the life of me find a list of hardware requirements for using it. It seems to require an arm processor, so if that's the only requirement, then you're good to go?

content: Yep! They're being manufactured now, and should start shipping around the 15th.Here's the final pinout diagram:

content: Nice project ! think this "Nano" format is great for hobby use or to leave it in a finished project.As for the question "Is it mbed.org compatible?" onhttps://developer.mbed.org/looking at platforms, I see no Atmel MCU's so I think the answer is no.

content: Isn't 500mA from a SOT23 regulator (?) a little optimistic... ? I'd derate to 100mA if I were you...

content: Quote from: tom66 on August 25, 2015, 06:10:41 pmI don't think so. With a 4.5V input, you're talking a little over half a watt. Thermal resistance is 184C/W to ambient, so temperature could rise to 110C over ambient, so as long as ambient is below 40C, that's below the 150C max. Plus the regulator will shut down if you exceed the max.Now, granted you wouldn't want to get anywhere near that temperature, but I went under the assumption that folks would want to know the peak current the regulator could deliver, not the continuous. It's unlikely anyone would be drawing 500mA from this tiny thing continuously.Also, if I were a newbie and I saw a limit of 100mA, I would assume that was the peak current the regulator could deliver and I would be constantly worried about exceeding that, even briefly.
