Inside of Dropad A8 - (believed to be Apad M7009 per Akira44oka)

Review by: Akira44oka

There are definately some differences between the Herotab C8 and the Dropad A8 internally. (or at least whatever similar device this is Apad M7009)
The C8 still has the 2GB NAND flash chip, but the this one does not.
Then this one has a different chip that the C8 does not.
Thanks: RobMtl007

TIP:
Using a hairdryer to heat the sticky tape may make taking the back panel off easier and safer. - Thanks Zaks Z

Photos of Dropad A8 (or something similar/generic) provided by Zaks Z:

Internals

Again this system (Dropad A8/Generic) is also missing the NAND Flash chip and has an extra chip in a different location vs. the Herotab C8.

Well... Only 3AM currently... gotta work in about 4 hours or so...
But just couldn't help myself.
Although I probably should have waited... as in my haste... I kinda cracked the back plastic piece... oops :{
- Luckily it is only minor.

I popped the back off and here is what I can find on the chips inside.
I updated the initial post.

Must go to Bed... will do Video reviews after work things are finished :}

Woww!! It's, like it have 2250Mah battery x2? So It is 4500Mah at all?? Thats very very very good

I hope my Haipad M7 will be have same battery inside!

 

[johnzo]

does it have a replaceable microsd for it's internal memory like the mid816?

Whether it is 2250 mAh at 7.4V or 4500 mAh at 3.2V... not exactly sure...
I just believe in comparison the way the websites list these tablets... it would be the same as them saying 4500 mAh

So, if i read this correct, you are waying it has equivalant to 4500 mAh? I am just currious because i noticed the merimoble site says.... Nevermind I see they must have updated it last night...

 

[pjku79]

OK, the only think I need to know before pulling the trigger is if the internal mini sd card is removeable or if it is sodered in?  Thanks for all of the help Tass.  I hope to be able to contribute once I get up and running.

Removable... but getting to it can be hazardous to your tablets cosmetic health.
You will see in my teardown video... I am actually trying to see if I can get a new back panel

[pjku79]

Have you already dont the teardown video?  I haven't been able to locate it.  Also, do you think it is possibly easier to get to now that you know how?

I finished recording the Teardown video earlier. 1 hour of time or so
I then went in to Edit mode. 4 hours of time or so
It is now in encoding mode. ETA 10 hours
It will then be uploaded to YouTube and the link posted here... but if you are subscribed to my channel you should see it.

It definitely takes time and effort to do these videos.

Tasselhof

 

[MrTasselhof]

I have linked photos to the first post.
I also have individual cropped images of each chip if you want... but figured the above would be good enough.
Having fun with Paint.Net... I took a general overview picture... and then overlay it with close-up more detailed images.
The composite image provides a good clear view of the various parts of the board... with only slight irregularities.

As to the Teardown/Internals Video itself....

The internals video will be 14 Minutes 36 Seconds.

It has been encoding for 8 hours and 15 minutes so far.
It still has another 2 hours and 15 minutes to go.

Then it has to upload the 1GB file to YouTube.
Then YouTube has to process it.

So I estimate it should be viewable in about 4 hours or so... which would make it almost 2:30AM.
I will post a final update in the morning before work.

Enjoy,

Tasselhof

I have posted the Internals Teardown video.

[size=12pt] Excellent tearDown Video MrTasselhof.
I am including a video that also shows a tear down of the Dropad A8
In this video the Nand Flash 2gig chip is not present.
Also the narrator(from Japan) points to a serial chip that he thinks may be for bluetooth, but on your Tablet this Serial Chip is missing, very interesting.
Here is the link to the video enjoy:

I actually had watched this video before doing my own... was helpful to see how to get inside... but I just wasn't careful enough.
So I put excessive warnings in mine :}

I have linked it in the first post along with notating the two differences.

Good video, thanks for both of them, guys. I left mine at home today, but I thought my back had the edge cover on it opposed to your flat back. I'll double check tonite. I also noticed your startup screen "mobile internet device" differs from my "MID". I wonder if theres any differences in our images, or if the on-board 2gb nand that you say is not in use plays any role in how the operating system boots or runs. I'd like to try your image on mine and see if theres any discernible differences, I'd think they are essentially the same though.

I have never seen the MID screen that you speak of... I also wonder if perhaps the 2GB NAND might be used as a factory reset/backup?
Is yours a Dropad A8, Herotab C8 or Haipad M7?

I have noticed the C8 takes longer to boot than my MID816, but the OS/Firmware feels a bit more stable on the C8.

AndroidTouchPC.com is releasing a "custom" firmware for the MID816 sometime this week that is suppose to have Android 2.3 on it "Gingerbread"... that should be pretty sweet and expected to be very solid. (although it will have to be purchased)

I wonder if they would consider making one for the C8.

I saw a Youtube video titled Dropad A8 and it has the MID screen. Mine is generic all the way. No indication of any branding of any kind. Its called a "Mid-Serails" (misspelled serials). I'll take some photos this weekend and hopefully get the back off also.

I would be willing to bet yours is a Dropad A8.
I think the verification will be the inside.
If you are missing the NAND Flash and have that other extra chip... I think it would be pretty conclusive to say it is a Dropad.

I state over and over... be very careful and take your time getting that back panel off... :}

Greetings Everyone:

Ok this is becoming very confusing with the Tablets model names.
Some Online stores name it the Dropad A8, or the HeroTab C8, or the HaiPad M7.

And now some breaking news some online store has named it the Apad M7009.

I believe this tablet comes from one manufacture: Shenzhen Saayi Technology Co., Ltd.

Then all these OEM or distributors buy the tablets with their specs and named it
as they want.

I think we will see lots of names for this tablet, who will sell the most?

Regards Robert

I'm sure thats the case, however theres at least one more variant with a Telechips processor and 2gb ram according to all the sellers on a few Shenzhen websites. If anyone has this model please chime in and let us know your specs.

EDIT: I fount the manufacturer website and it lists the Dropad A8 but shows it with a (nicer) metal back. It also has the "Dropad A9" which looks the same but with the Telechips proc, 2gb ram and ABS instead of metal case.

Good find Robert, I wonder how many different names this tablet will get. I also remember seeing one article where there are now knockoffs of the Dropads and now the official ones can be denoted by a yellow stripe on their box, and I see the pics on this website show a yellow stripe on the box.
