Choose Pico + GC9A01 round on the Hardware tab (or use the button above) and every pin on this page is filled in. The export writes the sketch, lcd_pins.h, the TFT_eSPI configuration, lv_conf.h and platformio.ini - a project that builds for this board as it comes.
The backlight is dimmable: give a slider or a button a Set backlight action.
Screens are designed for 240 x 240 px in either orientation, with LVGL 9 or LVGL 8.

GC9A01 / GC9A01A. 1.28" round panel used for watch and gauge UIs.

RP2040 (Pico / Pico W). PIO can drive an 8-bit parallel bus. Limited RAM - use a small partial draw buffer.

TFT_eSPI. Fastest for SPI panels on ESP32. Configured via User_Setup.h build defines.
