Building for it

A project is made for one toolchain, picked when you start it. For this board you can use three 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	Change a screen by editing a file on the board. No compiler once it is flashed. Start a project
ESPHome	Its maker runs the panel under an orientation byte of its own, which this export does not write yet - the picture and the touch would not agree.
ESP-IDF (C)	Espressif's own framework: esp_lcd, the component registry and idf.py, with nothing of Arduino in it. Start a project

At a glance

Part	Detail
Maker	Waveshare
MCU	ESP32-S3 Xtensa LX7 dual-core @ 240 MHz, 512 KB SRAM (+ 2-16 MB PSRAM on most modules)
Display	Chipone CO5300, 466 x 466 px, QSPI (quad SPI), 16-bit colour
Touch	Hynitron CST820 (capacitive, I2C)
Backlight	None: the panel is its own light, dimmed by a command
Memory	8 MB flash, 8 MB octal PSRAM (N8R8)
Graphics library	GFX Library for Arduino

Display pins

CO5300 on QSPI (quad SPI): QSPI clock 40 MHz, host SPI2_HOST, RGB colour order, inversion off.

Signal	Pin
SCK	GPIO 14
D0 - D3	GPIO 9, 10, 11, 12
CS	GPIO 15
RESET	GPIO 13

Touch pins

CST820: I2C address 0x15, 400 kHz, shares the display bus, X inverted, Y inverted.

Signal	Pin
SDA	GPIO 47
SCL	GPIO 48
INT / IRQ	GPIO 17
RESET	GPIO 16

Also on the board

I2C (GPIO 47 / 48) - SDA GPIO 47, SCL GPIO 48
Battery - analog input on GPIO 4
BOOTButton - input on GPIO 0
LED - output on GPIO 5

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

Check your revision. Pins from Waveshare's demo code and schematic (https://github.com/waveshareteam/ESP32-S3-Touch-AMOLED-1.43C). None between the vendor's code and the schematic: every pin in bsp_config.h is the net the schematic's GPIO table and panel connector give that GPIO. Waveshare runs this glass under orientation byte 0xC0 with the picture starting at column 8, and the preset does the same: the byte is on the Display tab, and a turned design is turned over it. Brightness is a command to the panel, not a backlight pin. Compiled; not run on a board here.

Designing for it in LCD Wizard

Choose Waveshare ESP32-S3-Touch-AMOLED-1.43C 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 CST820 is capacitive and needs no calibration. The firmware resets it and checks it answers on every boot.
The panel has no backlight pin: it is its own light, and its brightness is a command. Give a slider or a button a Set backlight action and it dims as a backlight would.
With PSRAM the LVGL memory pool can live there, leaving internal RAM for everything else.
Screens are designed for 466 x 466 px in either orientation, with LVGL 9 or LVGL 8.

The parts

CO5300. The AMOLED controller on most of Waveshare's 1.32"-2.16" boards, round and rectangular. Brightness is a command, not a backlight pin.

CST820. Found on capacitive versions of the ESP32-2432S028 "Cheap Yellow Display".

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

Every pin above, laid out to print and keep beside the bench. Generated from this preset, so it says exactly what the designer writes into lcd_pins.h.

From the people who made it

The board’s own documentation. Pinouts on vendor pages do sometimes disagree with the hardware in front of you - where this page and that one differ, trust your board and tell us.

Quick start - from an empty screen to firmware on the board
Boards and displays - presets, controllers, pins and touch in the designer
Flashing and configuration - PlatformIO, the Arduino IDE and first-boot checks
Troubleshooting - a white screen, mirrored image or touch that misses
