Duet 3 Mini provides two 2x5 ribbon cable headers for connecting a Fysetc 128 Mini Panel version 1.2 or 2.1 ('''not 2.0''') or compatible controller. When using a version 2.1 controller, the colours of the three Neopixel LEDs built into the display can be set using the M150 command with LED type parameter X2.
-We do not recommend connecting a 12864 display with ST7920 controller to the Duet 3 Mini because the 3.3V signals provided by the Duet 3 Mini do not meet the specifications of the ST7920 controller chip when it is powered from 5V. If you do wish to try it, you will most likely have to reduce the clock frequency (M918 F parameter) to get it working at all, and it may not work reliably.

Also, note that when configured for 12864 display with ST7920 controller, RRF provides the CS signal on the pin normally uses for A0 because that more closely matched the pinout of typical 12864/ST7920 displays.
