CubieTech’s “CubieAIO-A20” SBC and mini-PC run on a WiFi/BT-ready, Allwinner A20 “Einstein-A20” COM, and offer mSATA, GbE, mini-PCIe, and 7x USB ports.

CubieTech and its Cubieboard.org community site have begun selling a CubieAIO-A20 Board sandwich-style SBC which drives an all-in-one (AIO) mini-PC of the same name with a built-in 7-inch, 1024 x 600 touchscreen. The 172 x 106mm board is based on Cubietech’s Einstein-A20 computer-on-module, which offers the guts of a Cubieboard 2 or 3, including a dual Cortex-A7, 1GHz Allwinner A20 SoC. The CubieAIO-A20 board, AIO system, and the Einstein-A20 COM all feature -20 to 70℃ support.

The SBC model is available on Amazon for $122 with 8GB eMMC. The AIO mini-PC version goes for $144 at Amazon and $127.80 at AliExpress (see end of story for links).

Like other Cubieboards, the CubieAIO-A20 baseboard is fully open source and backed up by the Cubieboard.org community with open source Linux and Android images available. Cubietech says the Einstein-A20 module has “closed production materials,” but “available reference documents.” Indeed, extensive schematics and other materials are available.

The Einstein-A20 module measures 75 x 50mm, although one citation says 70 x 50mm. The COM is equipped with 1GB RAM, compared to up to 2GB for the $100, currently out of stock Cubieboard 3 (Cubietruck). It offers the ubiquitous, 1GHz Allwinner A20 with Mali-400 MP2 GPU, as well as 4GB to 32GB of eMMC or more secure and stable TSD (TSOP packaged microSD card) storage. The module also features an 802.11a/b/g/n and Bluetooth 4.0 module with an Ipex connector.

The Einstein-A20 module has a micro-USB port that can be powered by a wall adapter or an optional 5300mAh 3.7V LiPo battery. Other features include an RTC with battery, a UART debug port, a 200-pin expansion interface, and power, reset, and U-boot keys. The module supports the same images provided for the Cubieboard 2 and 3, including Android 4.2, Debian, and Linaro Ubuntu.

Specs for the CubieAIO-A20 and CubieAIO-A20-based AIO mini-PC are much the same except for the size and the addition of the AIO’s integrated, 7-inch, capacitive touchscreen with 1024 x 600-pixel resolution. In addition to the 8GB or more of onboard flash, you get a microSD slot and a SATA 2.0 mSATA interface via one of the two mini-PCIe slots.

The other mini-PCIe slot, as well as a SIM card slot, supports optional 3G or 4G modules. The Einstein-A20‘s onboard WiFi and Bluetooth are assisted by external antenna mounts and a pair of optional telescopic antennas. A GbE port is also available.

The CubieAIO-A20 is notable for offering 6x USB 2.0 host ports, the most of any hacker board we’ve seen. There’s also a USB device port and dual round DIN-style serial ports. This supports up to six serial ports, apparently via an optional extension interface.

The CubieAIO-A20 is further equipped with an HDMI 1.4, LCD and LVDS interfaces, an audio jack, a mic, and some speakers which are variably referred to as 1W or 2W. You get an IR receiver, a second UART, and a 54-pin expansion interface. Several switches, buttons, buzzers, and LEDs are also available.

    I was really hopeful, given the inclusion of miniPCIe and msata. Then they stopped at 1gb RAM? Man.
