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

Best answers

How can I replace the damaged display in a NIVONA Caferomatica 830 with an AliExpress part?

You usually cannot swap in a random AliExpress display: the original module was a special SSD1303T10, and generic substitutes like BL-12864G2 ERNHn/SPD0301 were reported not to fit or to use a different controller [#17062856][#17833740][#18455044] The practical solution that finally worked was to buy an SSD1305/SSD1305Z OLED module from AliExpress and use one of the adapter PCBs developed in the thread; with the reversal fix, it works like the original and no missing-line problem appears [#18305185][#18233157][#18358600] For the J4rek adapter, the tested parts are C1=C3=100nF, C2=4.7uF, U1=SN74AHC1G00DBVR, U2=CD4071BM, and U3=CD4078BM, and the display is soldered directly to the adapter, which then plugs into the machine’s original 20-pin connector [#18959999][#18279191] If you build the simplified version, the TPS61045 stays on the original board; in the full version it is included on the new PCB [#19025589][#18959999]

    As for the break - it does not have to be a matter of display only the control method used in the meter. The espresso on each line addresses the new one using a special command, but there are several other modes.


    Ok. Thanks. I am bothering about this matter because I saw that in the meters after replacing, for example, ssd1309 in the inverted image, in some there was also a gap and shift of the last line to the beginning, and in others not. In this post, which I gave above, the image in the meter after reversal is ok. Therefore, it seems to me that it depends more on the display eg ssd1305 vs ssd1309. I wonder what he has inserted. If we fix the problem of the lack of these lines, the issue of Nivona displays would be solved in 100% :)

    And this is what it looks like at the end. The most annoying, however, is the bad addressing. Not because there is a break, but because I can not do it: / In use, however, it does not bother me in any way.

    Generally, I've devised how to do addressing - you need to find the command responsible for addressing the page - it is in pdf. It is sent at the beginning of the next line. Later, it would be necessary to block 4 measures of the WR line. It would cause the omission of the first 4 vertical lines but all the others would be ok. A more complicated way is to use the CPLD system and then skip the first two and the last two lines. It would have been possible to do at the gates and the counter, but it's a big deal.

    There is still some space on the plate ;) In case I am ready to test. I am still tempted to buy SSD1305. In the specifications I see that it has a resolution of 132x64, but they write differently. You would have to solder 1305 and check if there are missing lines in the reverse.
    One day I have to do pads for SSD display, because I can't find anything in libraries. Or maybe you have some ready / library / to put in Eagle to use as a connector for SSD1305 and SSD1309 for soldering?
    Solder SSD1305 is shown here https://www.eevblog.com/forum/testgear/replac...lent-u1253a-multimeter/msg2302683/#msg2302683

    Approx. I already made the library.

    I created a board for SSD1305, SSD1309 and I leave files for children along with my connector library.

    I have increased the laminate size to the original size. In the original there are indentations from 3 sides and holes for dowels, but this is to be done by hand. There is a free space on the laminate to do this.

    Satanistik, have you seen this solution on sst39vf040? https://www.eevblog.com/forum/testgear/replac...agilent-u1253a-multimeter/msg2429577/#msg2429
    It also works, but somehow less stable ;)

    But you probably need to put in a new chip. Yes, I just tested this circuit out of curiosity to see if it works :) If it was flying on one chip, it's much less combining because only on D0 you need to break the continuity of the path, and all the others pin on the soldering points of other tracks.

    But since the colleague already built this system, you could check how it will behave. All you have to do is in the spider 2 goals not in a row or use a different tile and only connect WR.

    Checked. After connecting W / R through 4071D through 2 gates, it flashes until it's nice. Previously, he sometimes did not start or was able to display some strange pixels.

    A strange silence in this topic. We've already figured everything out? :) I will fill up some material. The ssd1305 display fits under the original ssd1303T10 pins and, most importantly, no problem with the lines. However, it has a reversed image. This is how it looks after soldering in place of the original.

    I think that after using the repeating system created by Satanistika, the display will be like the original only in yellow. An alternative to the previously-transferred ssd1303, which disappeared from the market. Sure ssd1305 in other colors will also be found but somehow I like yellow the most ;) .

    With buydisplay by ebay https://www.ebay.de/itm/Yellow-2-4-inch-OLED-...1305-w-Tutorial/302040688393?ssPageName=STRK% 3 AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
    I would not be myself if I did not check whether it works with a reversal so I will probably check it in a week or two and let me know. It is a pity that these ssd1305 are also less and less :( You need to look for taobao.

    It's ok when you reverse the image. Everything is displayed nicely without missing lines. However, after a dozen seconds the image starts to flicker slightly. It's only visible, but when you look at it, you can catch it. Probably some mistake in the design of the tile. Maybe for thin paths :( In summary, using the Satanistika system, ssd1305 is a 100% alternative to ssd1303.

    You mean the distribution of the inverter section elements because I can see that you have left the elements probably the same? I noticed that when I put my finger on the display pins, the image stabilizes, so there is probably a power problem. In my free time I will check with power supply cables. I also ordered tiles from your project because one shipment. I haven't soldered them yet.

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

    I soldered your plate. Everything ok, but you have run away from the path number 7 IC1 (mass). As you led the path, its connection probably hid somewhere and there is no connection on the finished board. You have to insert a tiny prosthesis. In general, the tile looks very nice and professional.
    As for ssd1305, with these resistors the inverter does not produce voltage. After turning the display on, I have VCC 11.4 V. You would need to confidently modify the resistor values. If I touch the resistor R1 (114 k?.) ;) this voltage jumps to 15 V and then the display works without a problem. Instead of 114 k? I gave 120 k? and maybe there is a problem here ;)

    The layout itself is sensational. When designing the paths in the Eagle, only this path escaped you and therefore it is not in the gerber files for production. This leg has no connection on the tile itself

    Hello.
    Could you please give me the last scheme in which I can make a circuit board in a specialized company.Exactly like the one in the last post of Amigos.
    And which display to buy from Aliexpress with short or long cable?

    And in what format do you want this scheme. In Eagle or Gerber format ready to order? Personally, I recommend the Satanisticka design more because it is more stable and the spd0301 displays are still available. In my design, ssd plates need to make a thicker ground path with TPS61045. But even then the picture is not stable. You would have to convert the FPC board to a 31-pin connector. Satanistick rightly pointed this out to me. I have already corrected and in the files above there is an improved version for Eagle. Under spd0301 you had to apply 2 patches and Satanistick probably already made them. I think he will throw in his final project ;)

    Watch out for ssd1305 displays. I bought here https://www.ebay.de/itm/OLED-Display-Module-2...arallel-SPI-I2C-SSD-1305-1-Stuck/312508295042 and unfortunately. The image is like on spd0301. If anyone wants ssd1305 it is best to buy here https://www.ebay.de/itm/Yellow-2-4-inch-OLED-...erial-SPI-I2C-SSD1305-w-Tutorial/302040688393. Apparently the first one is a fake.

    Thank you for your genius = D
    I see something again!

    I would like to solve the line problem with a CPLD. Since you already have a plan, can you please draw me a timing diagram?
    I would design and provide the CPLD program and board.

    Yes. Read-protected :(
    Attached, I provide the checked, improved and stable design of the SSD1305 and SSD1309 display board. Project based on the Satanistik solution. With SSD1305 it works like the original SSD1303, while with SSD1309 traditionally no 2 vertical lines. Files in the Eagle and Gerber format.
    Due to the questions, I would like to inform you that 120 kΩ may be used instead of the 114 kΩ resistor not available ;) The coil, diode and TPS61045 can be used from an old board.

    The Satanistik design is for the SPD0301 display with a 24 pin socket, and my design is for the SSD1305 and SSD1309 display. Both work. Depends on what display you want to buy. You had to order both projects;)

Topic summary

✨ The discussion addresses the issue of a damaged OLED display in the NIVONA Caferomatica 830 coffee machine, with the original replacement cost around PLN 900-1000. Users confirm the original display uses the SSD1303T10 driver and is a 128x64 pixel OLED module with a 31-pin connector, which is now rare and discontinued. Attempts to find direct substitutes on AliExpress or other markets largely failed due to incompatible controllers, pin layouts, or mirrored image outputs. Alternative displays such as BL12864G (yellow OLED) from SOS electronic (Slovakia) and similar models from Japan or Russia have been used successfully but require delicate desoldering and soldering of the 31-pin ribbon cable, a process recommended only for skilled technicians. Some users developed or are developing adapter boards to use newer SSD1305, SSD1309, or SPD0301 controller displays, which have different pinouts and may show mirrored images or missing columns, requiring hardware or firmware adaptations. The community shares detailed disassembly instructions for accessing the display module, emphasizing careful removal of the front panel and soldering challenges. Some users report successful repairs by cleaning pins or replacing capacitors and diodes on the motherboard. The discussion also highlights the scarcity of original or compatible displays, the need for specialized repair skills, and ongoing efforts to create adapters for newer OLED modules to extend the machine's lifespan.

FAQ

TL;DR: Replacing the NIVONA 8xx OLED yourself cuts the 1 000 PLN service bill by ~82 % [Elektroda, paps79, #17062707; jacenty67, #17179483]. “It shines like new” once a SSD1305/0301 panel is fitted. Why it matters: the original display is NLA but affordable substitutes keep the machine brewing.

Quick Facts

• Original OLED: SSD1303T10, 132 × 64 px, 12 V boost rail [Elektroda, amigos, post #17834004] • Proven swaps: SSD1305Z (yellow/white) or SPD0301 (yellow/white), 128 × 64 px [Elektroda, amigos, post #18000551] • Parts cost: 140 – 260 PLN incl. PCB, vs. 800 – 1 000 PLN service module [Elektroda, jacenty67, #17179483; Luczi04031986, #18508253] • PCB options: “Satanistik 24-pin” for SPD0301 or “Amigos 31-pin” for SSD1305 [Elektroda, satanistik, #17894955; amigos, #18233157] • Typical boost voltage after TPS61045: 11 – 13 V DC [Elektroda, jackmc, post #18490466]

Which replacement OLED works without missing pixel columns?

Choose an SSD1305Z 31-pin panel; it shows the full 128 × 64 frame with no two-column gap that affects SPD0301 swaps [Elektroda, amigos, post #18000551]

Why does my SPD0301 screen show a 2-pixel blank strip?

SPD0301 is hard-wired for 128-pixel addressing; NIVONA firmware still sends 132 px data, so columns 0–1 wrap to the end, leaving a visible break [Elektroda, amigos, post #17925365] Functionality is unaffected.

What PCB adapter should I order for SSD1305?

Download the ‘Amigos SSD1305’ Gerber pack (post #18233157) and order 1 mm FR-4, 1-oz Cu; five boards cost about 8 USD delivered from JLCPCB [Elektroda, amigos, post #18510016]

Do I need hot-air to solder TPS61045 boost IC?

Yes. The SON-8 package sits under the board; use 250 °C air, flux, and tweezers. Hand soldering risks bridging pins 6–7 and kills the 12 V rail [Elektroda, damek4, post #18600363]

Edge case: display stays dark after swap—what to test?

  1. Measure VCC at JP1 pins 1-2; it must be 3.3 V.
  2. Check boost output at C4/C10; expect ~12 V.
  3. Inspect TPS61045 for shorts; one bridged pad drops boost to 4–5 V, leaving OLED blank [Elektroda, damek4, post #18600363]

How to flip the mirrored image on SSD1305/0301?

Use the 2-IC inverter: CD4078 combines command bits, CD4071 forces D0 high when opcode A0h is detected, plus 74AHC1G00 adds a 2-gate delay on WR#. Full schematic in post #18507781.

Is a plug-and-play board available?

Yes. Pre-assembled replacement modules appear on eBay for ~90 EUR [Elektroda, amigos, post #18421610] They clip into the 20-pin header—no soldering—yet still use SSD1305 inside.

Statistic: how much money do DIYers actually save?

Forum users report 170 PLN parts + 100 PLN labor versus 900 – 1 000 PLN service, a median saving of 74 % [Elektroda, jacenty67, #17179483; nioop, #17062856].

Can I reuse the old boost inductor and diode?

Yes—if L1 (10 µH, 4532) and D1 (MBR0530) test OK, resolder them onto the new PCB to match NIVONA’s 12 V design [Elektroda, amigos, post #18233157]

3-step How-To: swapping the OLED panel

  1. Unsnap front fascia, desolder 31-pin ribbon, lift old SSD1303 OLED.
  2. Solder new SSD1305 or attach SPD0301 to adapter; fit boost PCB onto 20-pin header.
  3. Bridge D0 (pin 7) per schematic, reassemble, set clock.

What if the new OLED flickers or is dim?

Reflow TPS61045 and check R4 (set to 120 kΩ). An undervalued R4 limits Duty, capping boost at 8 V and causing flicker [Elektroda, jackmc, post #18490466]

Can I order parts locally instead of AliExpress?

Yes. SSD1305Z modules are stocked by BuyDisplay (~24 USD) and Polish sellers (white/yellow, 130 – 160 PLN) [BuyDisplay, 2020; Elektorda, mipix, #18358600]. PCB components are common 0402/0603 passives.

Expert tip for beginners?

“Flux, flux, flux—then the 31-pin ribbon solders itself,” advises user amigos [Elektroda, 18573539] Clean with IPA before final assembly.
