The SBC-X300 is a small single board computer based on the PXA300 CPU architecture. It is implemented by a CM-X300 module providing most of the functions, including integrated Bluetooth and wireless LAN (WiFi) interfaces. The SB-X300 carrier board providing connectors and several additional functions. The rich feature set of the SBC-X300 is customizable according to the price / performance targets of the user's application.

The SBC-X300 contains an electrical interface and slot for MMC/SDIO extension cards, which may be inserted and secured in the slot with no additional mechanical means, extending the system with capabilities such as a larger solid state disk, GPS or GSM modem.

Power supply options of the SBC-X300 enable its integration in mobile applications powered by a rechargeable battery. Charger and battery management support is provided on-board.
