If you need something that has clock speed in the hundreds of MHz and RAM in the hundreds of MBs then the Arietta G25 is maybe a good option - http://www.acmesy

Until this current wave of boards (CHIP, RPi zero) it was pretty much on its own in the land of dev boards - substantially beefier than Arduino, ESP8266 and Teensy 3.2 but way leaner than the RPi and BBB et al.
I still think it's a nice piece of kit even in the context of these new ARM boards.
Update: found some numbers on current draw - looks like out of the box it sits around 40mA idle, so slightly more than they tweaked the RPi Zero down to. http://www.robertoasquini.com/?p=148 http://www.robertoasquini.com/?p=148
- mikepurvis 11y agoLooks really nice. How do you find the low-level peripheral stuff? Past experiences have taught me to trust Atmel's data sheets and examples way more than the ST or NXP ones, but that's been on simpler chips/projects, so I don't know if it carries over to here. Also, is there an easy way to have an isolated realtime component, eg closed loop controller for motor drive? Could you just set up a hardware timer interrupt that preempts the kernel?
