NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement

hello everybody i want to repair display of this pcb ef691-oled with ssd1303t10 where i can found part

thanks you

Hoi, the manufacturer probably no longer has it, and others who understood it bought everything and stocked it up.

I used such a display:
https://pl.aliexpress.com/item/1005002192360374.html?spm=a2g0s.9042311.0.0.642d5c0fzQIg6I
and a small pcb from "j4rek"
https://www.elektroda.pl/rtvforum/topic3435827-270.html#18510195
Quite a different machine, but it runs smoothly.

Where do you buy components, because I don't need 100 pieces. Maybe someone has a few pieces to sell?

Is three a lot?

Maybe 10 pieces here, but it's only 4 zlotys

By default, you set the jumper on 2V7, and U4 and C4 are unnecessary. This is an option as if the systems have a problem with stability at 2.7V power supply. Theoretically, according to the documentation, they have a minimum 3V guaranteed.

Has anyone experienced low-voltage problems when using the standard 2.7 V supply? I normally solder in the MCP1700T-3302E/TT voltage regulator to get 3.3 V, but these voltage regulators are hard to get nowadays! (with the chip shortages everywhere)

thanks just where I can buy pcb

Anything can be done, but it will be a double-sided PCB.

I finally have my parts. The sdp0301 display can be connected, but in fact the image is reversed. Satanistik's circuitry works.

Where did you get this adapter to connect the display ribbon cable?


I want to buy a display SSD1305 on Aliexpress. Unfortunately there will be a mirroring problem. Where can you buy an inversion board?

Guys, where do I buy that mirror for that display? So far, there isn't a display that would swap piece by piece?

@ j4rek hi can you send me an email?

Today I purchased a display on the website. The display came and the store sells a copy of the J4rek, even the plate is signed in the same way ...

Hi everyone. Do someone have an extra pcb? I live in Germany, and I'm new to ordering pcbs online. The only providers that I found have very high shipping costs. I can find a complete replacement for €73, but I think I can do it myself for less money if I find out how to get a PCB delivered at me for less than €15.
thank you very much!

I bought a display and I don't have a DPS, can someone send it to me? I will pay

Hello everyone here in the forum,

Now the display on the 2nd Nivona is gone and I no longer want to invest the costs of Nivona service.
I came across your topic here by accident.
Getting a new display isn't a problem, but the circuit board is!
Does anyone have a soldered one for sale or a source for it.

Thanks and Regards
Gunter

I know there are some disturbances, but I have some 2.42 inch OLED and the drive IC is SSD1303T10.
If you need you can contact me.
My email: yunwang1709(_at_)gmail.com.

If anyone is interested in the image reversal plate in this Nivona, I still have a few pieces.
Regards, Luke

Hi Guys,

I have purchased a ssd105 display from Aliexpress. But I need a reversal plate to avoid mirroring. Where can I buy it?

Hey
Anyone else offering @j4rek tiles for Nivona and shipping to Estonia?

Hi Guys,

I'm working on replacing SSD1303T0 module with SSD1305 by FPC.
I wonder if anyone is interested?

Does anyone else have a plate to flip the image in this Nivona?

Gentlemen, I wanted to thank you for a lot of time devoted to this exhausting thread, in particular @Smoczy for a super refined plate, it fits perfectly. By the way, memory swap is a great idea.



I didn't want to wait for the display from the PRC, I bought SPD0301 on Allegro and quickly connected the leads with a wire from the coil, it's so nice.



While desoldering the old display, I saw that the tape was broken. I have the impression that from vibrations and it could be soldered, but I damaged the display with a hair dryer, when I heated it, something was visible for a moment.

What other better displays are available besides the SSD1305? Do any forumers have connectors that fix the mirroring defect? I am interested in.

First, see if the connector is cracked - this can be soldered.

My respects!!!
First of all thank you all for your input in solving this problem, in particular amigos, satanisk, j4rek, dragon.
I have a great desire to try to fix it, because the spouse can hardly see anything anymore while making coffee. As for skills, I have soldered something there but I have no experience with hot-air. I think I'm most afraid of the tape for the screen.
Of course, if I understand both ways correctly, I would choose option 2 because of slightly easier soldering (no need to move that small TPS chip from the original board as in option 1).
So to sum up, you need a new SSD1305 display, order a j4rek v2 board somewhere + components to solder yourself. Is there an option to order from some service the board already with components? Nonetheless, if any of you have redundant components, partially assembled, I would be happy to buy back.
And one last thing, this may be a bit silly, but I find it hard to believe that there is no replacement for the original display that would not reverse the image, has anyone perhaps looked recently?

I am interested in a reversing plate for Nivon.

SSD1303 to 1305. Thanks.

NIVONA SAVED!!!
I just received the OLED I bought from AliExpress.
After re-soldering it on my machine, the display is completely normal.
No image reversal!

406,91 zł - a nice price in this link, it is on Allegro at 349,00 zł - I spent almost 150 zł on everything, only soldering was a lot, because I did not want to wait for shipping from PRC.

Will this fit? https://www.olx.pl/d/880703650/?bs=olx_pro_listing&isPreviewActive=1&sliderIndex=0
