The ODROID-C1 quad-core single-board computer is now available, and it's only $35.
Like Raspberry Pi, the ODROID-C1 is a credit card-sized single-board computer, but despite the similar price point, it's much more powerful. Short for Open + Android, the ODROID-C1 boasts a 1.5GHz quad-core ARM processor and is capable of running Ubuntu Linux 14.04 or Android KitKat. The board has 1GB of DDR3 RAM.
Despite its small size, the ODRIOD-C1 features a bevy of ports and slots. It has four USB 2.0 ports, a micro-HDMI port, RJ45 Ethernet, a row of GPIO (general purpose input/output) pins, a MicroSD slot, micro-USB connector, Infrared (IR) receiver, and an eMMC module socket, which offers storage access two to three times faster than via the SD card.
