The pcDuino3 is a $99 micro-computer that can run on Linux or Android

To get a sense of perspective on the theory of relativity, the recently introduced $1,099 21” iMac is touted to be cheap – at least for an Apple desktop, and here we are with a $99 dual-core computer that is simply known as the pcDuino3. This single-board computer will be able to run on either Android or Ubuntu Linux, where it will be powered by a dual-core ARM Cortex-A7 processor, all enclosed within a steel case. Other hardware specifications of the pcDuino3 include 1GB RAM, a paltry 4GB of internal memory, a microSD memory card reader for expansion purposes, 10/100 Ethernet connectivity, a trio of USB ports, and a 3.5mm audio jack. There is also an HDMI port that allows the pcDuino3 to keep up with the times in order for it to hook up to an external display.

Another day, another small-form-factor PC. This one, the pcDuinos3S, meets that fine line between budget-friendly and usable, being priced at $99 and able to run either Android or Linux, depending on your needs. We’ve got a rundown of its features after the jump. The pcDuino3S is a case-toting alternative to the slightly cheaper and case-lacking pcDuino3, which is sold for $77. With the 3S model comes the same features, as well as a white box around the board that saves those without DIY inclinations some hassle. The pcDuino3S features a 1GHz Allwinner A20 processor and Mali-400 graphics, as well as offering 4GB of internal storage space and a single gigabyte of RAM. The storage can be expanded with the use of PC’s microSD card slot (supports up to 32GB). Other features include a standard 3.5mm audio jack, a trio of USB ports, 10/100 Ethernet, and HDMI for use with a TV or monitor. Users can run either Ubuntu 12.04 for Android 4.2 without issue.
