Divoom Tivoo IC components (part 1)

December 8, 2019 estebon 8 Comments

Here we will discuss the electronic components that compose the circuit board of the Tivoo, in this first part we will just find what the components are and what they do.

Lets start with the screen

Here we can see three main IC of the board

ICN2053 – 16-channel PWM

Here you can see a link to this IC

ICN2012

Here you can see a link to this IC

This is basically a merge between TTL 74HC138 and 8 powermosftets.

F130G4 0 Microcontroller

Here you can see a link to what I think this IC is.
https://datasheetspdf.com/parts/GD32F130G4U6.pdf?id=976678

This IC is aparently from a company called GigaDevice, the IC have diferent naming, so may be a clone, Seems this IC was originally a GD32F130G4 from GigaDevice, the Die match at least in the shape. Also the logo looks like GigaDevice, I may be wrong tho.

Now lets jump to the Main board.

This board have 5 major IC

XB8608A 8u1 – Lithium Battery Protection IC

Here you can see a link of what I think is this IC
https://datasheet4u.com/datasheet-parts/XB8686E-datasheet.php?id=1243989

This IC seems to be a Once Cell Lithium-ion Protection circuit. The original IC seems to have been XB8686E from Sysemi I presume is similar to that link since the numbers kind of match and the way it is installed relates to the pdf. you can see the top 4 legs are unused, or in this case, maybe connected to the negative part of the battery altogether.

25Q127CSIG – Flash memory

Here you can see a link to what I think is this IC
https://www.digikey.com/product-detail/en/gigadevice-semiconductor-hk-limited/GD25Q127CSIGR/1970-1027-1-ND/9484777

This IC seems to be Flash memory, the original IC seems to be GD25Q127CSIG

CS8326S B144 – Audio Amplifier

Here you can see a link of what I think this IC is
https://datasheetspdf.com/datasheet/CS8326S.html

FP8102 SAe-00L Li-Ion Battery Charger

Here you can see a link to this IC
https://datasheetspdf.com/datasheet/FP8102.html

ANYKA AK1052DN048 GZSH04I18 Microcontroler/DSP

Here you can see a link to this IC

We will discuss the function of each of this ics in future post.

DIVOOM tIVO dISASEMBLY (teardown)

December 8, 2019 estebon 14 Comments

This Post will show my disassembly process as well as screenshot of main components and tips and tricks.

The main structure of the Tivoo is not glued, it consist of some snap locks and screws.

The first step is to remove the knobs, there are two knobs in the unit, those you just need to pull with a bit of force and they will slide of, they are held in place only by pressure and friction so very safe to remove.

Second step is to remove the plastic faceplate. This is the trickiest part, as the face plate is attached with latches.

In the next picture I highlighted the latches.

To start disassembling the device, I started from the knob corner moving up using a guittar pick.

Once the faceplate is removed, the tivoo looks like this.

After that the tivo screen is composed of 4 components.

*Glass
*Diffuser panel
*ligth mask
*led array

The following images is the device after removing the Glass

The following image is the device after removing the diffuser

The following image is the device without the grid mask.

Here are the images of all the 4 components of the screen.

Tivoo glass, diffuser, mask and led display.

Here is other shot of the LED display turned off.

To continue the disassembly process, we need to remove some 6 screws pointed in the next screenshot.

from this point the screen is just held in place by friction against some panne like material. to extract the screen I used one screw driver in one of the holes and pulled as follows.

After that you can just unplug the two wires, the big one is power and data, the small one is the microphone.

Here is another picture of the main board of the screen. (The following picture is highRes so you can see the components.

In the case you can see the main battery (a lithium 18650 w 3000mah), the speaker and another board behind the battery (hard to see). You will also see other two screws that need to be removed to continue with the disassembly.

After that you can remove the inner assembly from the outer case.

Now to open the inner assembly you need to remove itehr 4 screws.

After that you will need to remove other three screws that attach the circuit boar to the assembly and unglue the battery.

To Remove the battery I just gently moved until the glue broke. Also note that the board itself have some of the same glue, so you will need to pull it gently until the glue gives up after removing the 3 screws from the picture.

Here you can see the board separated from the assembly.

Next Here I add some high resolutions from the front and back of the circuit board.

That will be all in this entry, thanks

Note: to see high res in your phone you may need to switch to desktop site mode.

Divoom Tivoo

Divoom Tivoo Retro Non Destructive INSIGHTS

December 7, 2019 estebon Leave a comment

For Black Friday I ordered a Divoom Tivo, since I think the pixel art on it looks so cool. And also to learn about the workings of this little neat device.

The device itself is very nice.

The grid of the screen is a 16×16 pixels, and the whole screen measures 579×509. you can see a mock of the configuration in the following sketch.

The values in the above image are my measures with caliper and may be a bit of and the may not even add, but they give a nice approximation. (good enough for me at least).
