Reference boards with LCD-TFT panel

Reference boards with LCD-TFT panel

ST offers a wide range of reference boards such as Nucleo, Discovery, and Evaluation boards. Many of them embed display panels.

For STM32 reference boards featuring an on-board display but not embedding an LTDC, the DBI (FMC or SPI) interface is used to connect the STM32 with the display.

For the other STM32 boards, the LTDC is used to interface with the display panel.

These reference boards can be used to evaluate the graphic capability in specific hardware/software configurations.

Table 25 STM32 reference boards embedding LTDC and featuring an on-board LCD-TFT panel summarizes the STM32 reference boards embedding LTDC and featuring an on-board TFT-LCD panel.

An available board B-LCDAD-HDMI1 (that can be purchased separately), allows the DSI conversion into HDMI format to connect HDMI consumer displays.
A DSI to LCD adapter board B-LCDAD-RPI1 (that can be purchased separately) provides a flexible connector from the microcontroller motherboard to the standard display connector (TE 1-1734248).

2 Another discovery board is available STM32F769I-DISC1 but with no embedded display. The display can be purchased separately as B‑LCD40‑DSI1 ordering code.
