Just wondering as I am planning out my future projects are we going to see a hardware refresh to the base netduino and netduino plus? It seems that after the launch of the go they are starting to look a little under-powered.

Hi jimox, Thank you very much for your feedback and enthusiasm. We're listening. BTW, the SAM7X micros have a really nice balance of features and performance-per-watt. The Cortex micros like those used on Netduino Go and the Shield Base use quite a bit more power and would require some special consideration to use on a traditional Netduino mainboard. For Arduino-form-factor projects--the SAM7X on Netduino and the enhanced Arduino shield compatibility built into Netduino and Netduino Plus--continue to provide both the nicest standalone hardware and the best value in the NETMF market. Chris P.S. If you're looking for a Cortex-class Netduino, we're currently shipping the Shield Bases with a free upgrade to the 512KB Cortex-M3 chip. You need to supply power and use a serial cable for debugging...but technically the Shield Base is a bit of a super-Netduino in itself :)

Chris, Looking back at my original post under-powered might not have been the correct term to use. Under spec'd would have been more accurate. In my case I am mainly concerned with code space. I am running OneWire (so I can't bump up to v4.2) on an n+ using networking so I have limited space. The possibility of an out of memory exception on a board controlling power to 120v hardware has me a bit concerned.

Understood, thank you. We appreciate your feedback.

To traditional microcontroller developers, the 42KB of RAM on Netduino Plus is like a big ocean...but anything that doesn't end in mega- or giga-bytes can make us .NET developers nervous :)

Three more quick notes:
  • The Netduino Plus 4.2 firmware frees up a bit more RAM for your application. At least 42KB (and in some cases getting closer to 60KB...but we spec 42KB to be conservative)
  • .NET MF 4.2 has an enhanced garbage collector, which really helps assuage any OutOfMemoryException concerns.
  • We are continuously working on both new products and updated product designs. Your feedback is really helpful in achieving the right balance for future products.
Chris

P.S. We're hoping to integrate CW2's OneWire support into the 4.2 firmware soon. I don't have a date...but we definitely don't want to leave your application behind on 4.1.
