Another 9331 router chip product... Meh We use this in our product and it has issues. You have to be real careful on how you wire much of the gpio. If they are in the wrong state at power on the thing won't boot. Also it does not have real SPI. It is bit banged. This has caused some issues too.
The plan at this point for us is to go to the intel Edison. Yeah, it is more expensive but has a lot more gpio, Bluetooth le, faster, more ram, more flash, and is even smaller. The 70 pin connector is not that bad to work with. -Jerry > On Apr 29, 2015, at 12:08 PM, Manuel Muro <[email protected]> wrote: > > Hi All, > > Here is a kickstarter project that I am supporting for what I would like > to call a "nanocomputer" as it has a rather beefy engine running at 400MHz, > with 64MB of DDR RAM in a very small footprint: > > https://www.kickstarter.com/projects/onion/onion-omega-invention-platform-for-the-internet-of > > Being the microprocessor geek that I am, this processor, MIPS 24K, is > much more powerful yet is more power efficient than the current ARM Cortex > offerings, but this is really hidden from the end-users as they can program > in a number of higher-level languages such as Python, PHP, Ruby,Javascript > (Node.LS) and others as the system is running a full version of Linux. > > However, what has really got me excited about this project is that they > offer peripherals that are completely stack able.
