Instructions to use ender 3 V2 stock LCD with SKR mini E3 V2/V3 or even E3 Turbo.
Since Ender 3 V2 & Ender 3 S1 are using the same knob LCD screen, they have slight different pin out compared with the LCD12864 or BTT TFT Screen. SKR Mini E3 V2/V3 are viable drop-in replacements for Creality 4.2.X boards as they are equip with TMC2209 in UART, Linear Advance and many more extra ports & features. Making it the best alternative to buying a new board from Creality.
Installation is very easy and board has exactly same dimmensions as Creality v4.2.2 and v4.2.7, connector layout is also very similar.
Only hardware modification required is a display cable adapter made with 8 dupont F-M cables.
Hello. Congratulations on the videos. They helped me a lot. I have an Ender 3 V2, and I replaced the board with an SKR MINI E3 V3. I bought this board because the listing stated it was 100% compatible with the Ender 3 V2. However, it’s not 100% compatible since a cable modification is required. Would it be possible for you to send me the arvo firmware.bin that you used on your printer? This way, if the LCD doesn’t work, I’ll know the issue is with the cable and not the firmware. Thank you. Marcus Guedes from Brazil.
I have an Ender 3 V2 Neo with a TJC screen (not DWIN). Do I also have to modify my display cable for the SKR Mini?
I have the SKR MINI E3 will that work for my ender 3 s1??
Are BEEP and ENT (pins 9 and 10) swapped? Did BTT swap them on you? I’m looking at the pins.

BTT’s github identifies:
BEEP as pin10 PB5
BTN_ENC as pin9 PA15
we didn’t swap them. the v1.2 might have different pinout compared to v2 and v3
Please explain further. I have tested the swap of the Ender3-V2 screen with a 12864LCD screen using the same cable on the printer, and with correct firmware and each screen works perfectly, so proves the cable for V2 screen and 12864 screen therefore must the same, Secondly: I can use the same 12864 screen on a SKR mini E3 V3 board with its supplied cable and it also works, this proves the wiring is the same. therefore it makes no sense that the V2 screen would suddenly need a different cable to work on the SKR board, what am I missing here?
DWIN wasn’t natively support with SKR Mini E3 board, under marlin source code, it mentioned it has to be rewired. I think the main reason could be the pinout pre-configured inside the marlin source code.
ok thanks, I shall research this and try to fix the software, rather than needing a cable change.
Any news on this topic, I´m getting my Board for the Ender 3V2 on Monday and would really like to know if I can use the Display or not?
There are certain pins that should not be changed (i.e. 5V) because of hardware design. Not everything is modular (afaik). I went through the whole thing back when the issue was fresh a few years ago. Either modify the existing cable and crimp or buy one off Ebay…or in my case I went with the BTT tft50. If you do decide to go the cable route, I would recommend this firmware: https://github.com/mriscoc/Ender3V2S1
I am looking to upgrade the board in my e5 plus to an skr mini E3 v3. Can I use the stock display for this or do I need to buy the btt tft v3? Also, can I use the Insanity automation dwin 7.4
SKR Mini for Ender 5 Plus has change it to TFT screen. the wire is incompatible.
Do you reckon this tutorial would work with the SKR 3 series?
haven’t tried, but if for SKR Mini E3 V3 then yes. if SKR 3, not sure since it’s different board.
There was an issue discussed on github that there would be freezes when homing unless:
“You can get serial to work by editing the STM32Duino code and changing the USB_EP to single buffer instead of double buffer.”
I couldn’t figure out how to do that. (Can’t find a .platformio folder)
Is this still needed if
https://github.com/Jyers/Marlin/archive/refs/tags/v2.0.1.zip
is used?
yeap, it works but you need to compile a different firmware for SKR Mini E3 V3
I have an Ender 3 v2 printer and would like to use the SKR Mini E3 V3.0 to replace the Creality 4.2.2 board. I prefer to keep my Creality stock LCD. Will your SKR Mini E3 v2.0 instructions above work for the SKR Mini E3 v3 board?
