The Orange Pi One features an Allwinner H3 1.2 GHz quad-core ARM Cortex-A7 processor, ARM Mali-400MP2 graphics, 512MB of RAM, and a microSD card slot for storage.
It has HDMI output, 10/100 Ethernet support, a USB 2.0 port, a micro USB port, a 40-pin Raspberry Pi-compatible header, a camera interface, and a few GPIO pins.
It’s available for order one from AliExpress. Note that shipping to the US brings the total price to $14… which is still not a lot of money for a computer.
USB 3.0 will most likely raise the price of this mini PC. I think the USB port will mainly be used for connecting a keyboard, mouse, game controller, or Wi-Fi adapter, so USB 2.0 should be good enough for connecting accessories like a keyboard to the PC.
I read posts online that said licensing fees are a little more expensive than USB 2.0 because the copyright/patent holder wants more money than USB 2.0 license.
