12864 display (ST7920) on Duet 3 Mini5+
The level shifter IC should be 74HCT08, not 74HC08.
It's a typo IC is 74HCT08
You should ground the unused 1A and 1B inputs of the 74HCT08, or connect them to +5V.
I will do this later in a soldered pcb board
The Duet 3 Mini has a card detect input, SPI2_CD in your diagram. You should connect ............
You are briliant
It is not shown in the diagram but it is present. (The Maestro didn't have the connector).
When the card is inserted it changes from 0.4V to 0V. I think that should be fine.
I have currently connected SPI2_CD to ground and it works.
Thanks a lot.
I still have one final question.
I have an accelerometer that I want to connect to the PanelDue connector.
Will this work in combination with the LCD sd card reader (same SPI bus)?
I will not run both at the same time.
@diy-o-sphere the accelerometer is normally connected to the temperature daughter board connector. I think it should be possible to use the PanelDue connector instead, but I haven't tested that. It should work OK with the LCD card reader if the cables are short.
the accelerometer is normally connected to the temperature daughter board connector.
My pIan was, that by using IO.0 only one plug is required.
But it's just to play around.
I will buy the new toolboard as soon as it is available here.
Thanks for the announcement
I don't feel disadvantaged, quite the opposite.
Hello i am in the process of making a small Production run based on @DIY-O-Sphere schematic. IT will be Board which will be directly olugged Into the Mini;)

The adapters are here and they work. I tested it with the classic Display, the BTT 35 and the BTT 70.
Please PN if you want one! You can choose between a plugin type or a "extension" one For plugin see the image above

@pcr Hi, adapters in compatible with mks mini12864 v2.1?
If the LCD has a ST7567 chip, the adapter is not required.

Does the adapter also work with a Duet2 Wifi (Ref. 1.04, Firmware 3.3)?
Thanks to the support of @pcr i was able to replace my prototype board.
Finally a clean wiring!
