"The founder is prosperous, the open source hardware is blooming everywhere, so that many Chuangke will look at the eyes, and not to say that the single-chip level, such as the various Arduino series hardware products, the microcomputer-level development board is not more than ten kinds, below Briefly introduce 10 open source hardware platforms, so that Captain will understand the diversity of this field.
1. [Cubieboard] (CB)
Here is the CB2 purchased by mainstream as an example. Note that Cubietruck is indeed CB3, but not discussed here.
The CPU of CB2 is allwinner (full) A20. Its architecture is ARM Cortex-A7 dual-core. The performance of this CPU can be more cheap Android tablets. Run Android is not so powerful, but it is still enough. Running Linux is quite good, light load is not obvious.
The rest is configured for 100M Ethernet, onboard 4GB NAND storage, extended TF storage, 1G DDR3 memory, 3.5mm headset + Mac compound jack, SATA, HDMI + VGA (must-range circuit) + LCD (needed circuit), Camera Camera interface (must be an external circuit). Price 350.
I went to visit Cubietech. Their support investment is continuous and active. Convenient to Android, Debian and Ubuntu (Linaro) on CB.
CB is an early opening and source hardware. CB1 announced although later than Raspberry Pi, the domestic listing and promotion and Raspberry PI are even earlier (due to the early out-of-flight in Raspberry Pi and the introduction of China's time difference). Therefore, there is still more relatively more people who have CB in China.
CB is more troublesome is that the expansion interface is 2.00mm instead of standard 2.54mm, which may need to expand a class, in order to directly connect 2.54mm various electronic modules, slightly.
The circuit boards of CB1 and CB2 are identical, all configurations are also consistent, just the CPU retreat to Allwinner A10 (ARM Cortex-A8 single core), the price 300.
Generally speaking, there is not much money to upgrade to dual-core CPUs, and the value of buying CB1 is not large, unless certain performance sufficient application.
Here you will mention allwinner. Zhuhai General is an ARM chip manufacturer of China, and their CPU is generally used to make cheap Android tablets.
The biggest feature of Zhuhai General is: they are more about programs rather than product companies. The full-awaited CPU is generally manufactured and optimized for a single Android application scenario. When you leave the partner, you can provide a full set of schemes and SDKs that use the CPU to make Android devices, almost no modification can quickly produce products.
But at the same time, this idea also caused objective shorts of chip development, mining and data construction. That is to say, using this chip to make a manufacturer, it is easy, but it is easy to connect the most basic information. Many people got the "pit" and "cottage" after the Datasheet of the General CPU. In fact, the reason is here. The whole greenery is not good, but the origin is not here.
2. [Raspberry Pi] (RPI)
The A version of the source is very small, so don't discuss it. It is only discussed B version here.
The Raspberry Party is a pioneer who loves and hate.
The CPU of the RPI is Broadcom (blog) BCM2835. Its architecture is an ARM11 single core. This architecture is full of renewal of all smartphones, as well as all other mini PC board ARM Cortex-a architectural generation, belongs to the last generation of classic ARM products before opening the Cortex multi-product line. This CPU's performance is desperate. Low killing, just moving the mouse card type. Saying good is to ask software developers to pay attention to optimization, saying that almost sneaks. Fortunately, the built-in graphics processor can be strong, and hard solution H.264 is not lacking, graphical performance is still expected.
The rest is configured for 100M Ethernet (shared USB bandwidth), no semi-load storage, all dependence on SD storage, 512M SDRAM memory, HDMI + simulation composite video, CSI camera interface. The price is about 210 (suspected to escape the value tax).
Love is that community support is too full, do not rely on manufacturers, there is a very rich and diverse application and information. Hate is that the performance is low to make people refers; Boyong and open source are enemy, various hardware APIs and drivers do not let go of developers; Foundation's hardware and software design vulnerabilities, system function is not proven, "digging pit is not filled" .
My attitude is: Linux novice first board recommended RPI, the skiller is not recommended. But since it is not expensive, it can always be a try to buy as the second board.
3. [PCDUINO] (PCD)
Take a newly released V3 as an example.
The CPU of the PCD-V3 is allwinner (full) A20. Unanimously discussed with CB2.
The rest is configured for 100M Ethernet and WiFi (via USB), onboard 4GB NAND storage, extended TF storage, 1G DDR3 memory, SATA, CAMERA camera interface, HDMI + LVDS LCD screen interface, IR infrared input, 3.5mm headphone Mike Composite Jack.
Pcduino is interesting in his extended interface, is fully compatible with Arduino. So as long as the 3.3V version of the special Arduino (that is, Arduino Tre) expansion boards available, it can be used directly for PCDUINO.
Pcduino's software strategy is also very interesting. The PCDUino factory system is an easy programming Ubuntu (Linaro) rather than the usual Android. Special Arduino IDE and SCRATCH are built into the system environment, which can be used directly to direct the extension pin for hardware programming, which is very convenient.
I want to say that as a propaganda of hardware developers and hardware DIY, maybe PcDuino is closest to me to make the Mini PC as the ideal of hardware development infrastructure.
The PcDuino manufacturer's update is also active. Their Learn Center has a lot of information that can be used (not the other board users of PCDUINO).
PcDuino is hateful, the price is the price ... PCD-V3 set price is up to 680, Tuhao consumer goods.
All other PCDUINOs are single USB ports, and USB HUB is almost necessary. It will cause some trouble.
The CPU of PCD-V2 retreats to Allwinner A10, which also cancels SATA, LVDS, CAMERA, IR infrared input, 3.5mm headphone Mike Composite Jacks. Price 400. It is also a high consumption in the board of the full-scale A10.
V1 seems to have little source, no discussion.

ATOM E3815 MonPacterial Computer with Intel® AttractionTM (Bay Trail) Facing Digital Signage, Portable Medical Equipment, Industrial Control System, and Car Information Entertainment (IVI) system with secure content delivery capabilities with secure content delivery.
4. [MK802]
Using my understanding, MK802 is not a single product, but a name that many Android TV bars.
It may be a variety of CPUs such as Ruixin, all kinds of CPUs, which will not be high. Basically only wireless networks. Flash + TF expansion card slot. Single HDMI output. All only use of the old android of 4.1 or 4.2, can not brush Linux, cannot be programmed, and cannot be used for hardware DIY. Price 200-400 does not wait.
Vendors are different, universal three no, there will be no people in the after-sales. Can only be used to turn ordinary TVs into a performance-not-made Android smart TV.
There is no value of any purchase. Who is buying him?
I really want to assemble Android smart TV, buy this goods is worse than buying various famous boxes such as Tmall, millet. Although those experiences are still debatable, they must be better than this kind of street.
Other good MINI PC:
5. [Cubietruck] (CT)
Cubietruck is CubieBoard3.
CT is the luxury version of the Cubieboard product line. Replace the front two generation board design.
The CPU is still a full wish A20. Onboard NAND to 8G, memory is added to 2G DDR3, Ethernet upgrade to Gigab (important!), Increase the board WiFi, increase the direct VGA output, increase the 3.5mm headset + Mac compound jack, increase the SPDIF fiber output, Add IR infrared input.
This board is full in the peripheral configuration, no matter how roid and linux playing Android and Linux. Price 540.
6. [Banana Pi] (BPI)
Emerging products that have just been widely promoted in China in the first half of this year.
The CPU is a full-awaited A20 (the back of the board). 1GB DDR3. No board storage, all SD card storage. Gigabit Ethernet (important!). HDMI + composite video + LVDS LCD screen. 3.5mm Headphone output, onboard Mike. Onboard IR. Camera interface.
I will know if I look at the shape of the board. All goals of this board are compatible with the Raspberry Pi. I have seen the Banana Pi team, according to their self-reporting for this goal, they have a large sacrifice that violates the ideal goals on board design, such as insisting on using SD instead of TF.
Vendors even make downward compatibility with ARMV7, providing only replacement of kernel and bootloader, while Rootfs remains unchanged with Raspberry PI.
Price 299. The board of the board is the cheapest.
7. [BeagleBone Black] (BBB)
American team's work. A few Sunday instruments (Deyi, Texas Instruments, Ti) on the market.
The CPU is TI AM3358, ARM Cortex-A8 single core (architecture equivalent "A10).
Single chip microcomputer development board wonderful recommendation:

512MB DDR3, onboard 4GB EMMC storage, TF card expansion. Micro HDMI or LCD video output (requires special Shield board). Baq Ethernet.
TI is good, in the foreigner, actually love to play ... English information is a lot. The addition of TI Datasheet is also available. Senior hardware developers will like TI's big company.
Onboard storage is a good thing, EMMC built-in controller, gameplay, and SD cards, save a lot of trouble.
The BBB is hate to death is the Micro HDMI! There is too little space next to the interface! If you use HDMI to Micro HDMi adapter, you will die directly to block the next TF slot and USB interface! Even with the original Micro HDMI cable, the USB cable is inserted with each other with each other. Which brain disabled board!
Price 380 (Shenzhen Yingji Gains Authorized China) / 430 (US Import Edition).
8. [RADXA ROCK]
Rui core microphone quad-core high plate. Quad-core development boards can be succumb to the current market.
The founder once is one of the cubieboard creators.
RK3188 CPU of Rockchip (Ruixin). The architecture is ARM Cortex-A9 quad-core.
2GB DDR3 memory. 8GB NAND storage supports TF extensions. Baq Ethernet (doing so high but not more than thousands of trill !!!). Onboard WiFi + BT4.0, real-time clock (very uncomfortable), SPDIF fiber, composite video, 3.5mm headset + Mac compound jack.
Not actually used. Ask for more use experiences.
Price 600.
9. [WRTNode]
Very chic board. 4 * 5cm area can run Linux practical items.
The idea is to make the router chip into the development board. So the system uniquely supports the special Linux distribution of OpenWRT.
The CPU is MT7620N, unpredictable MIPS architecture.
DDR2 64MB memory, 16MB SPI Flash. Onboard 802.11 BGN wireless network. It can be extended to 500 megapher Ethernet interfaces. 30 ~ 150mA @ 5V low power consumption. This is a positioning between Arduino (single-chip level) and the Raspberry Pi (ARM high performance board). In need of using Linux, it is not harsh in performance, but there is a lot of applications in space.
Low configuration, the price is low. Current beta price 150.
In May 2014, he had just opened public beta, absolute pioneer card. Dedicated to players who are not afraid of difficulties and challenges.
10. 【龙 芯智 龙】 (Dragon Core "Opening" open source hardware series board card
Dragon core. It is the domestic MIPS CPU. Just It is the CPU of the computer that is the only computer used by RMS. The goods are genuine.
Longxin also launched their open source hardware board "Opening Long" program.
The biggest feature of this board is currently known is that the expansion interface is really rich, almost all package. Even the interface of this Arduino branch project is available.
