Hi,
I'm looking for an embedded board with these minimum caracteristics : - maximum size 150x150mm - low consumption : less than 1A with a 5-7V power supply - one (or more) i2C link - a free RTOS running on with free tools (to compile, download, ...) eCos would be the better. - one usable (not only for programming) RS232 link with a DB9 connector
A do not need a powerfull CPU, a 20MHz microcontrolers with two or three timers, 512Ko flash and RAM should be enough.
I only found : - small, with OS and hardware but power conumming and high frequency - OS, hardware, low consumption but really big board - small, low consumption, hardware required but no free RTOS - small, low consumtion, OS but without the required hardware (may be the better solution because I can propably create the hardware with a bit of electronics)
Eventually, if someone know a board that fill these caracteristics...
Thanks, Guillaume
