CubieBoard4/CC-A80 in Factory

Posted by Heng Yan in A80, CC-A80, cubieboard4, open source hardware

After 8 months working, we lunched into the first batch mass production of CubieBoard4 (aka CC-A80) two days ago.  We modified the hardware design again and again. Right now, it’s the 3rd revision which is very encouraging in my heart. I’d like to tell you the reasons if you have been waiting for it. We rejected the 1st version because the audio connector (earphone+ microphone jack) is too high. That mean we chose a audio connector liked by none of us. Some connectors were also too close to each other. In the 2nd revision, we found that the power output was not strong enough and the heatsink was not suit for repairing and DIY as well.

After lots of test and experiments, we finally fixed the hardware and its features are as follows.

In the factory, I took some photos with my phone and now I’d like to share them for all of you.

Ewell case has come, miniPC not be far behind

ewell_case_1

 

ewell_case_2

 

Cubietruck’s Ewell case is the first one specifically designed for Cubieboard 3 and it makes Cubietruck become a high-end and classy commercialized MiniPC product. Ewell case can support a 5300 mAh lithium battery and a 2.5-inch mechanical hard disk drive or solid state drive. The entire product has a net weight of 362g and you can definitely feel its weight when you hold it in hands, which makes me fond of it very much. I have followed up the whole design process of this case. After two major modifications, we are basically satisfied with the third version. After a long process, we finally have the chance to present it to Cubieboard fans. I have made several times of trial installation after I got the production version. Here is the recording of the whole installation process for your reference.

Ⅰ. Accessories and tools

ewell_case_3

1. One piece of Cubietruck mainboard

2. One set of Ewell case

3. One 5300 mAh lithium battery, with 2.54mm of 2-pin plug, which also can be made by yourself.

4. 2.5-inch hard disk drive (SSD is better due to its faster reading, better resistance to vibration, lower power consumption).

5. One SATA wire, which is included in the standard package of Cubietruck

Tools:

6. Prepare a roll of foam rubber to stick battery. Try to buy the product with better quality and stickiness. Usually you can buy it in the stationery shop in China.

7. 3-mm Phillips screwdriver. Remember the specification: 3-mm cross-shaped.

 

Ⅱ.Installation process recording

ewell_case_4ewell_case_5

 1. Stick the lithium battery

Use the scissors to cut two trips of foam rubber and attached them to the bottom cover of the Ewell case. You should control the length of the foam rubber properly. After attaching the foam rubber to the lithium battery, pay attention to the direction to stick the battery. Just follow the direction in the photo below.

Notice: If the battery is installed in the wrong direction, the battery cable will not be long enough, which will make it impossible to continue the installation.

2. Install the hard disk drive 

ewell_case_6It is relatively simple to install the hard disk drive. The Ewell case is designed with a 2.5-inch hard disk drive bay and 3.5-inch hard disk drive is not supported. Put the hard disk drive at the right place as shown in the photos above and then lock it with short screws in the back, as shown below. The short screws are provided in the accessories package of the Ewell case.

3. Install the button for resetting and updating

Install the button according to way shown above. The conjoined button is placed on the top, which takes not much difficulty. Please note that the LED light guide bar may not be installed for the moment, which will not affect the normal use. If you have to install it, you may need to find someone else to help you to fix the light guide bar. Otherwise, the brute force may easily damage the keys on the PCB main board.

4. Connect the battery and hard disk drive

Connect the battery, hard disk drive with the circuit board before putting the Cubietruck main board into the Ewell case. There are 4 sets of wires to be connected, as shown below: directly insert the SATA data cable into the corresponding black connector, the red and black 5V power cord into the middle 5V connector, yellow and black 12V power cord into the 12V connector below (this 12V power line virtually does not work in the 2.5 -inch hard disk drive, here we just put it in the right place only), red and black battery cable into the corresponding lithium battery socket.

5. Install Cubietruck circuit board

The next step is to put the circuit board into the case, which I think is the step requiring highest skills. First, there is only one allowable way to place the Cubietruck circuit board into the Ewell case. Be sure to make the network port VGA side (the rear edge circuit board) get in first and the USB base side (the front edge of circuit board) get in last. Prior to pressing down the front edge of circuit board especially the USB base, ensure the board edges are in close contact with the interior of Ewell case with no gap, as shown by arrows in the following figure. If it is your first time to install, it is recommended to make a trial installation without connecting the battery and hard disk drive because it will become much more difficult with them connected.

I finished the installation single-handedly, so I just put the relatively heavy bottom case on the table and put the lighter top case standing up in order to complete the installation. Once again, first fully put the rear edge of the board into the case, and then the front edge. Ensure the conjoined button is at the right place before putting the front side in. After the Cubietruck circuit board is completely in, check whether the each key is in normal state, and then check whether each interface is in the right position. If there is no problem, you can fix the cover with screws. Before fixing the cover, tidy up the wires and ensure they stay in good order in the case.

6. Fix the rear cover with screws and attach the non-slip mat

After the necessary check, you can fix the rear cover with screws. Use four slightly longer screws, as shown in the photos below:

ewell_case_12

After fix the screws, the final step is to attach the non-slip mat. The whole process takes about 20 minutes with a total of six steps. If it is your first time to install it, be careful and take your time. Do not damage the circuit board. If the power key doesn’t work after installation, it may be caused by battery protection. You need to use DC5V power supply to break through the battery protection board.

Cross-Platform Hybrid Cloud with Docker based on Cubietruck

Chanwit is an Assistant Professor at School of Computer Engineering, Institute of Engineering, Suranaree University of Technology, Thailand. He co-founded SUT Aiyara Cluster Laboratory, where he has been co-developing low-powered ARM-based clusters for processing Big Data using Apache Spark and Hadoop. Chanwit is also a top contributor of Docker Swarm, a native clustering engine for Docker. One year ago, Chanwit and this team built a great Spark/Hadoop cluster with Cubieboard2. Recently, he has developed a cross-platform hybrid cloud system atop Docker with 50 unit Cubietruck boards. If you are interested in the cloud and big data academic issues, go Here for more details.
