Letux Cortex 15 - Small OMAP5 SoC module

Coming soon. The Letux Cortex 15 is a very small OMAP5 based SoC module. It comes with 2 GByte DRAM and eMMC as well as a full audio chip (TWL6040). Multiple interfaces allow to connect displays, peripherals, speakers, etc. through low-profile board-to-board connectors.

For evaluation purposes there is a variant that adds a micro-USB socket so that the board can be powered and operated without being plugged into a carrier board. Just connect to some Notebook's USB port and access the Linux console.

Software: the board runs the Letux Kernel which can be installed together with a Debian root file system through our makesd script:
