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	ESPHome ships the RM690B0, which is a different controller.
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	Raydium RM67162, 240 x 536 px, QSPI (quad SPI), 16-bit colour
Touch	FocalTech FT3168 / FT6146 (capacitive, I2C)
Backlight	None: the panel is its own light, dimmed by a command
Memory	16 MB flash, 8 MB octal PSRAM (N16R8)
Graphics library	GFX Library for Arduino

Display pins

RM67162 on QSPI (quad SPI): QSPI clock 40 MHz, host SPI2_HOST, RGB colour order, inversion off.

Signal	Pin
SCK	GPIO 47
D0 - D3	GPIO 18, 7, 48, 5
CS	GPIO 6
RESET	GPIO 17

Touch pins

FT3168 / FT6146: I2C address 0x38, 400 kHz, shares the display bus.

Signal	Pin
SDA	GPIO 40
SCL	GPIO 39
INT / IRQ	GPIO 41
RESET	not connected

Also on the board

I2C (GPIO 40 / 39) - SDA GPIO 40, SCL GPIO 39
IMU - QMI8658, at 0x6B, on I2C (GPIO 40 / 39)
Battery - analog input on GPIO 1
BOOTButton - input on GPIO 0

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-AMOLED-1.91). 1) TF card: no conflict on this revision - the schematic and the code's V1 branch agree (SPI, SCK 47, MOSI 42, MISO 8, CS 9). The code's DEFAULT is the other board (VersionControl_V2: SDMMC, CLK 9, CMD 42, D0 8), so the vendor's examples as downloaded do not mount a card on a V1 board until that macro is commented out. The glass has rounded corners whose radius Waveshare does not give, so the designer draws them square: keep what matters out of the corners, or set a corner radius on the Display tab once it is measured. On the board and not in this preset: TF card: it is wired onto the panel's own SPI lines, which the export gives to the panel alone. 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-AMOLED-1.91 / ESP32-S3-Touch-AMOLED-1.91 (V1 board) 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 FT3168 / FT6146 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 240 x 536 px in either orientation, with LVGL 9 or LVGL 8.

The parts

RM67162. LilyGO T-Display-S3 AMOLED and Waveshare's 1.91" boards.

FT3168 / FT6146. Waveshare's AMOLED boards (1.43", 1.64", 1.8", 1.91", 2.06").

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.
