Building for it

A project is made for one toolchain, picked when you start it. For this board you can use one of the four:

Toolchain
Arduino (C++)	Every board, every widget and every peripheral here. The most control, and the most to set up. Start a project
MicroPython	The MicroPython export has no driver for this controller yet.
ESPHome	ESPHome has no driver for this controller.
ESP-IDF (C)	The NV3041A's quad SPI start-up is not among the quad panels the ESP-IDF export writes (the MicroPython export's, whose table it follows). The Arduino export drives it.

At a glance

D0 - D3	GPIO 21, 48, 40, 39
CS	GPIO 45

Also on the board

SPI (TF card) - SCK GPIO 12, MOSI GPIO 13, MISO GPIO 11
SDCard - SD card, on SPI (TF card), CS GPIO 10
The TF card slot, on SPI 12/13/11 with CS 10 (Guition's pin table).

The preset adds these to the Hardware tab with the board, so a sensor can go straight onto the connector.

Check your revision. From Guition's own package for the JC4827W543 (Arduino demos, pin table, getting-started guide): the NV3041A on QSPI (CS 45, CLK 47, D0-D3 21, 48, 40, 39, no reset line), started with Guition's own register table from the copy of GFX Library for Arduino they ship, IPS (inverted); backlight GPIO 1, lit high; GT911 touch at 0x5D on SDA 8, SCL 4, reset 38, polled (INT is GPIO 3, unused by Guition's code); TF card on SPI (CLK 12, MOSI 13, MISO 11, CS 10); speaker I2S (BCLK 42, LRCK 2, data 41). Guition's package has no schematic, and none of its code uses the TF card or the speaker: those are from the pin table alone. USB-C goes straight to the S3, so the serial log needs USB CDC On Boot (the export sets it); GPIO 17 and 18 are UART1 in the pin table. LCD_TE is on GPIO 0, the BOOT pin, so the BOOT button is not offered as an input. Guition's LVGL demos draw through a whole-frame canvas; the export draws in parts, as GFX Library for Arduino's own definition of this board does. Compiled, not yet seen on the glass: if colours are a negative, turn Invert off; if the picture is torn or misplaced, say so. The R (resistive) and N (no touch) models need other touch settings.

Designing for it in LCD Wizard

Choose Guition JC4827W543C (4.3" capacitive, ESP32-S3) 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 GFX Library for Arduino configuration, lv_conf.h and platformio.ini - a project that builds for this board as it comes.
The GT911 is capacitive and needs no calibration. The firmware resets it and checks it answers on every boot.
The backlight is dimmable: give a slider or a button a Set backlight action.
With PSRAM the LVGL memory pool can live there, leaving internal RAM for everything else.
Screens are designed for 480 x 272 px in either orientation, with LVGL 9 or LVGL 8.

The parts

NV3041A. 4.3" QSPI panel - RGB-like size without burning 16 pins.

GT911. The address is selected by the INT pin level during reset, so wire INT and RST if you can.

ESP32-S3. The only common Arduino target with a hardware RGB565 LCD peripheral. PSRAM is effectively required for RGB panels.

GFX Library for Arduino. Moshi Liu's library. Best QSPI/AMOLED and RGB coverage. Configured in code.

The pinout on one page
