LCD Touch Display for the discovery kit STM32MP257F-DK

MEige · ‎2026-02-14

Hello,

unlike the STM32MP157F-DK2 the STM32MP257F-DK is not equipped with an Touch/LCD.

Is it possible to use an identical/similar LCD with the STM32MP257F-DK (that means: are the appropriate connections on the board)?

Hello @MEige ,
The STM32MP257F-DK board does not embed a DSI connector like the one we have on STM32MP157F-DK2 board.
You have 2 native connectors for display in the design of the board: HDMI or LVDS.

For LVDS you can refer to the one we use with STM32MP257F-EV1 board, this will work the same way (Display + touchscreen).

Kind regards,
Erwan.
