Modular SBC runs Android and PicUntu on Cortex-A9

Mar 5, 2014 — by Eric Brown 2,695 views

[Updated Dec 11] — Haoyu Electronics announced a sandwich-style $60 “MarsBoard RK3066” SBC equipped with Rockchip’s 1.6GHz dual-core RK3066 SoC, and running Linux and Android.

Haoyu Electronics previously released MarsBoard A10 and MarsBoard A20 single-board computers based on Allwinner’s A10 and A20 system-on-chips, respectively. Those product pages are now inaccessible, as the Shenzen-based vendor focuses on its new Rockchip RK3066-based MarsBoard RK3066. The new board first came to our attention in a Mar. 3 CNX report.

The MarsBoard RK3066, not to be confused with Embest’s Freescale i.MX6-based MarS Board SBC, consists of a SOM-RK3066 baseboard combined with a CM-RK3066 computer-on-module installed on top of the baseboard. This sandwich-style SBC construction is similar to that of the Wandboard, except in Wandboard’s case the COM plugs into the bottom of the baseboard. The dual-board approach lets customers design their own baseboard or upgrade to a future CPU module, says Haoyu.

The CM-RK3066 module taps Rockchip’s dual-core, 1.6GHz RK3066 SoC, which has also appeared in the Rikomagic Cloudsto MK802III LE stick computer. The Cortex-A9-based SoC features a quad-core Mali-400 MP GPU, and supports 1080p video and OpenGL ES 2.0. Other Rockchip based SBCs include Radxa’s Radxa Rock, which moves up to the quad-core RK3188.


The CM-RK3066 module is further equipped with 1GB or 2GB of DDR3 RAM, and 4GB or 8GB of NAND flash, although the higher options do not appear on the checkout page. Haoyu also mentions eMMC flash, but does not list the amount.

When you plug the COM into the SOM-RK3066 baseboard, a MarsBoard RK3066 is born. A microSD slot supports up to 128GB of storage, says Haoyu. A 10/100 Ethernet port is provided, along with an HDMI 1.4 port, four USB 2.0 host ports and a micro-USB OTG port. One of the USB ports is used for an included WiFi dongle.

There’s also a USB serial console for debugging, a self-defined IR remote, an S/PDIF audio headphone jack, and an LCD connector that supports capacitive touch. The board includes a camera interface a pair of 50×2-pin expansion interfaces, and a 20×2-pin interface. The Rockchip optimized PicUntu version of Ubuntu is available along with a version of Android 4.2.2 for tablets.

    it seems that this SBC has incorrect specification listed here. According to this article the SBC should have 2 fast ethernet ports. However the manufacturer states that only a single ethernet port is available. Can you verify this?

    best regards, Ladislav Petrus

      Thanks for the correction. We had it right in the main text, but wrong in the summary of specs. It’s now fixed, thanks to your comment. –Rick
