Hi,
this is a smart server called Duckbill in a thumb-drive format based on the i.MX283. It's a really low cost solution usable with or without casing.
It is intended to be set up as a small home-server for automation purposes. It comes with Debian Linux as operation system but without any specific user programs.
The stick can be operated either at a USB power adaptor or at a USB port of your router.
Since Duckbill runs Linux you are totally free in software development.
The internal connectors can be used as UART, SPI, I2C, ADC or GPIO. So it's up to everyone to develop his own expansion board.
