Both of them have attached batteries and using SSH / HDD . Lime2 is a web-server and running since winter, rebooted only for updates. The only problem i had was the DRAM clk - i have and old revision that crashes with default uboot config. Micro is used as a test/dev system, the 2.54mm headers are perfect for that, and it's seen quite a lot of abuse - shorts, overvoltage, some hardware mods, etc
Consider adding a heat-sink on the cpu - either a 20x20m porous ceramic one, or a standard aluminium one. I've learned that the PSU is very important. Look for a high quality one. For the micro i use a 8V/1A transformed based psu, as i need the isolation. For lime2 i have some 5V/2A switch-mode psu reused from a usb-hub. It can keep the input voltage to 4.9-4.8V under the highest load i can generate. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
