Thanks for the feedback 👍

Which mainboard firmware have you tested with? If you used Klipper and the config for the mainboard/display combo is not listed in the wiki, would you please share the config with us?

guys, clarification:
1.with layout
[display]
lcd_type: st7920
cs_pin: EXP1_4
sclk_pin: EXP1_5
sid_pin: EXP1_3
Encoder_pins: ^ EXP2_5, ^ EXP2_3
click_pin: ^! EXP1_2
works very unstable, it starts up one time out of seven, ten.
2.checked with the layout:
[display]
lcd_type: emulated_st7920
en_pin: PD10
spi_software_sclk_pin: EXP1_5
spi_software_mosi_pin: EXP1_3
spi_software_miso_pin: EXP1_6
encoder_pins: ^ EXP2_5, ^ EXP2_3
click_pin: ^! EXP1_2
works steadily, but the most important thing: do not press any buttons during operation - reset the screen! otherwise the screen will stop working and you will need to restart the raspberry
