This system allows users to custom tailor their design to particular peripherals they need quickly. By stacking multiple daughterboards together, a precise solution can be created. Currently, daughter boards available include a Camera COG (3MP colour CMOS camera), Multimedia COG (320x240 TFT Touchscreen LCD, Sound Card), Ethernet COG (10/100 Mbit networking) and Breakout COG (development tool with
.1" IDC breakout of pass-thru bus, MiniSD card slot and RS-232). Many additional daughter boards are under development and to be released soon including a robot controller, power controller, GPS/Bluetooth/Wifi board and a plug-in FPGA solution. In addition, all these designs are "open" so that users can easily adopt and develop their own daughtercards using standard PCB manufacturers.
