Activity link: [Free Application] is more suitable for the Chinese than the Rober Zero - can play Tensorflow's BPI-M2 Zero
I don't have anything recently, I have been looking for some fun open source platforms. It happens that only 15 dollar banana Zero is in front of him, and I don't hesitate to take it. Talking about the banana sent Zero, then you can't avoid the berry zero, and now today's Raspberry Pisero has upgraded to the Raspberry Zeor W, what is the upgrade, you can refer to the simple but not simple Raspberry Zero W, this The text is not explained in addition. Compared with the Raspberry Pisero, Banana Pi Zero is still similar to the upgrade of the Raspberry Pis, together.
Banana Pi BPI-M2 ZERO
Simple packaging does not mention, in order to easily, look at the naming of the substantive packaging to banana pi bpi-m2 zero, but the following writer is called Zero, everything is easy to understand, but also Mouth.
The interior is a banana-talented zero with a static electric bag, and the visual is only the size of the adult thumb.
Because it is an open source, the tutorial, hardware schematic, system mirror, source code, etc. are available online can be found online.
Seeing the true capacity of the banana Zero, the first reaction should be "This intent is really suitable for the development of prototype", it is small and exquisite, only 60mm * 30mm, with the raspberry zero is the same size, with the current space is slightly larger The product application is directly plugged in.
The layout of the banana zero is very interesting, the chip and the interface are layout in front, and the back is basically passive electronic components, and at least visual presentation is very comfortable.
Front interface: MicroSD card, Raspberry Pisero, because of the space limit, of course, it can be said to be cost limit, there is no equable EMMC storage, so the system can only be stored in microSD, the MicroSD card supports 64GB extension; microSD There is also a packaged WiFi @ BT module, the positive base AP6212, support 802.11b / g / n, SDIO interface communication; MiniHDMI, the author said that this interface line does not, it seems to be used first. Get up; the serial port is three through holes located between the McIROSD card holder and MiniHDMI, and it needs to be processed.
↓ Banana Party is equipped with two mcirousb interfaces, close to the external power interface, close to the middle part is the MicroSB OTG interface, can extend Ethernet or more USB peripheral interfaces via USB HUB, convenient for some users to use mouse keyboard classes The tool; the outside is also equipped with a CSI interface, supporting 5 million pixels, support 1080P @ 30fps camera.
↓ Banana panel 40pin extension IO port, can be said to be the only user who can customize the function of the banana party, which is worthy of these IO ports with 40Pin extension IO ports on the Raspberry Piece, so you can use it directly There are many prototyping modules developed by Raspberry, so it is still very convenient to use.
The definition of the 40PIN IO is as follows:
↓ Banana panel The core processor is the H2 + of the total science technology, integrated 4 core Cortex-A7 processor, MALI-400 MP2 GPU, performance masonry, not necessarily, but relying on its own mature banana faction Series, there is a more mature application reference, and the extension of the Raspberry Pivot is also a relatively good supplement.
I have to look at it. The banana Zero does not emphasize how high performance is based on the full history H2 + SOC, which is equipped with 512MB SDRAM, but it relies on the extended interface of the Raspberry Pist and the similar operating system. It makes it easy to apply to prototype development.
Used
For users who do not have MiniHDMI and the corresponding display, actually use the banana to send Zero or quite embarrassment, the author is the banana party started through the serial port by welding a serial pin.
Android and Linux systems can come in bananas run here with a Linux system, based on the version of ubuntu 16.04.3 Armbian_5.36_Bananapim2zero_Ubuntu_xenial_next_4.14.3_desktop_preview_build_by_bpi.img.img.zip, the system can be used to burn to MciroSD card system Win32DiskImager Burn tools, specific operation processes can refer to previous evaluation articles.
Another important thing, the banana sent zero did not carry onboard antennas, but only one IPEX RF interface seat, which requires an additional antenna.
Before you have previously purchased a TE's WiFi antenna, + 2dB ~ 4DB gain, the banana sent official recommended + 2DBI, just active.
After completing the above steps, you can view the system boot log through your own PC's serial tool such as PUTTY.
Armbian is a lightweight Debian system and Ubuntu system dedicated to the ARM development board. In other words, it is very suitable for the banana zero. This performance is not very high open source board computer, username / password: Root / 1234
To play the advantages of banana Zero, the network is essential, the banana faction does not have a wired network port due to the volume, so configuring WiFi into the necessary steps, you can choose to configure static IP, you can connect the banana to ZERO directly through SSH The additional serial line connection is eliminating, it is more convenient to operate.
The information of the banana Zero H2 + SOC, the CPU is 4 core, the highest frequency 1.2GHz.
The results of the banana Zero performance via sysbench are as follows:
136S achievement, this time is between the Raspberry Piece 2 and the Raspberry Pieces, which can be seen in the Banana Party Zero's performance is also between the Raspberry Pivot 2 and the Raspberry Pieces, as a 100-year-old Open source board is still very nice.
Tensorflow can also play
Recently, AI is particularly fire, so, I also caught fashion, I installed Google's deep learning tools in the banana sent Zero Tensorflow, recommending the gods on Github (link), this original is transplanted in the Raspberry, but The banana party is equally applicable, and its core is based on the transplant on ARMV7L, so I believe that many ARM processor-based boards can be used, and they can try it. Of course, the only thing is currently the version of this Tensorflow is only 1.1.
After the installation is complete, start Tensorflow is also very simple, enter python to enter, configure Tensorflow.
It can be seen that Tensorflow has been successfully running through a "Hello, Eeboard", and is an important tool for current and in the future. The importance of Tensorflow is self-evident. I recommend it to understand or learn deep learning. Experience one.
Small knot
In general, banana Zero is still very nice, with competitive prices plus expansion interfaces that can be compatible with Raspberry Zero, whether hardware expansion or ecological extension is extremely convenient. You must know that although foreign trees are called a few dollars, it has a lot of money to buy in China. Even if it is known as Taobao to Tao's foot, it is necessary to use the price of about 170RMB, so for the Chinese people, bananas Zero is still a significant price advantage, of course, because the board itself is limited, there is also a place that makes the author are not very satisfied, such as there is no SATA interface, the onboard MiniHDMI is somewhat embarrassing, no standard antenna, if it can be improved, That will be better.
