Compared to the $89 ODROID-U2 board, you’ll get an extra USB port, access to I/Os, a power button, support for external RTC, and better input power protection, but lose the digital microphone. ODROID-U3 is however considerably larger than ODROID-U2 (83 x 48mm vs 48 x 52mm), but it’s still a credit card sized board.
The company is also selling the U3-IO shield ($20) for the board, in order to provide easy access to 36 I/O pins including GPIOs, PWM, and ADC ports. The board has the same size of ODROID-U3, features Atmel ATMega328 and 2 Arduino compatible headers, and schematics (PDF) are available. The board comes with 12 metallic / plastic PCB spacers.
There are actually two version of the board: ODROID-U3 and ODROID-U3 Community Edition. The only difference is the price: $65 for the former, and $59 for the latter, and that you can only order one piece of the community edition version. The company also sell accessories separately for the board including a DC power adapter, a plastic case, a microSD card with Linux or Android, Bluetooth and Wi-Fi modules, a USB-UART board, 8/16 and 64 GB eMMC modules, a micro HDMI cable, a USB IO board, an active cooler, and an RTC backup battery. Shipping is expected for January 14, 2014, and adds $25 to the cost.
