Computer is pretty complex device that can do a lot, but seems not enough. This is why Bunnie Huang has started an open source laptop. He packed a lot of features in to it that sounds like a candy for any hacker. And so it features a Quad core ARM Cortex A9 CPU running at 1.2GHz, several memory types; bootable microSD, SD, DDR3-1066 SO-DIMM up to 4GB, SATA-II. Probably most exciting here is FPGA next to CPU. It takes care of most hackable interfaces like 8 digital and 8 analog I/Os . Additionally it can drive 8 servos. There is a Raspberry Pi compatible interface header. Other standard stuff like USB, audio, WiFi header, LCD connector, UART ports, HDMI are as you would expect on any laptop.
There are couple Ethernet ports available – 1Gbit and 100Mbit. Power supply is designed on separate board and can be connected through battery board interface. Battery interface board was designed to support battery packs used by RC enthusiasts up to 4S1P (4 series cells). They are cheap, they support super fast charging. Laptop is still work in progress project, but it already boots Linux and does basic job. Its power should be enough to run normal applications. Probably it could be used for building smart systems like intelligent robots as there are so many I/Os to play around.
We recommend EasyEDA for circuit design and PCB prototype
