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

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]

    Thanks. From him I bought 2 pieces at the auction last time and are already waiting with friends in Germany. Unfortunately, friends are currently in Poland and are going to be in two weeks. Only then will they send it to me :(

    How long did you wait for the implementation?

    I ordered, delivery a few days from Slovakia ... and again I'm enjoying the "operation" of the coffee machine after the exchange. This time in yellow :)
    My friend who has the skill and access to the equipment (especially the microscope) has turned over - I do not recommend to anyone who is not fluent in these blocks.

    Buddy, is there any chance for you to help me repair the display, how would I send it to you, of course for an additional fee?

    Those with the SSD1309 controller also work: NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement Unfortunately, the controller is placed on the tape vice versa and the image is mirrored horizontally. However, I managed to get around this problem: NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement Unfortunately, it is not so easy: NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement If I finish it, I will post the solution on the forum.

    NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement At the top of the display output from the coffee maker - view on the plate pins, not the LCD tape itself. At the bottom, the display on SSD1309, here for the change, 31pin pins. There is an I2C / SPI version on the Allegro and, unfortunately, the inactive D0-D7 pins have been connected to ground and so maliciously that there is mass from the front and back (it is impossible to cut the ground path without soldering the tape) and a short between the pins. I soldered with a tape to the tape points, but you could do a dedicated tile. The signs match. BS1 and BS2 connect to + which gives the bus 8bit mode as 8051, which is separately RD and WR. This combination will give us a picture, but a mirror - you can get used to it. NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement

    Thank you very much. In two days the display will come to me, spd0301 with 24 pins, I will try to use your diagram. If it fails, I will order ssd 1305 or 1309, because the pins have the same.

    The system for removing the inverted image does not require FPGA - three CMOS circuits were enough.

    Cool. Eventually someone took care of this problem and the topic started. Congratulations on the solution. We are waiting for the final description. "redzid", maybe you can check faster, what I wanted to check with spd0301. For me it has the same pins as ssd1303 except for the extra BS0, except that it is arranged differently. The connection of BS2 and BS1 to +, BS0 to - should give it the 8bit bus in accordance with table 6.2 https://www.usmicroproducts.com/sites/default/files/SPD0301_1.0.pdf. I think that spd0301 would not require additional layouts only for the board / adapter /. I already have the spd0301 display, I ordered this plate https://www.aliexpress.com/item/FPC-FFC-flat-...rectly-inserted-DIY-0-5-mm-spacing-connector- 6P / 32827105259.html? Spm = a2g0s.9042311.0.0.49914c4dhj9wJj and I am just waiting for the entire display module to check it out. It's nice that the topic has moved.

    Nice, because the order of the tracks is from the same page in both displays, so on a possible tile there would be only 2 intersections of paths. On the schematic it would look something like in the screenshot below. If you find an error in this drawing, let me know. Always two heads, it's not one ;) Connectors in the example diagram.

    Today I connected the spd 0301 display via the connector / adapter according to the amigos drawing. Indeed, the display works, but unfortunately the image is a mirror image, as in ssd1305 ssd1309, etc. Satanistick solved the problem, but apart from the pictures, he did not include the diagram, it is a pity. Maybe he'll call you again.

    Well, it's not like a mirror image. Also there is a break like in 1309? I've read that there are displays that can be forced to invert the image. I do not know much English, but I'd like to delve into the specification https://www.usmicroproducts.com/sites/default/files/SPD0301_1.0.pdf. Especially in Chapter 7. The display of the image may depend on the condition on the specific display pin. There is someone wise who would study it? I see that the speech in it is also about mapping 132 columns, but I do not know what to associate :) Next week I should already have my displays, I will pokombinuję ;)

    Old LCDs were reportedly working in 132x64, and those replacing 128x64. Here is the problem with the lack of columns.

    And you were looking, maybe, in the case of sdp0301 is it possible to force him to image 132x64? It seems that thanks to your modification it should also reverse the image in the same way as on ssd1309. According to the specifications, sdp 132x64 is called to give the pin high on LS, but this pin probably is not derived :( If your modification on sdp0301 works, I will be able to check it out within 1.5 weeks. Then the problem of the display replacement and the missing columns would be completely solved. In the case of sdp0301, there is also a better solution, because at least you do not need to solder the display, but only connect to the FFC24 connector. The small connector therefore has more space on the circuit board for the arrangement of the circuits. The board would only need to somehow connect with the original connector on the module's board. As for the tile, you would need to talk to someone who does it every day. I tried to play on the Eagle, but you have to have an idea and skill. In any case, if someone did, I would also like to take tests.

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.
