Waveshare ESP32-S3-Touch-LCD-1.46B
1.46" 412x412 IPS LCD (SPD2010, QSPI), SPD2010 (integrated touch) touch, PCM5101A (I2S DAC, no I2C control) audio, TF card, QMI8658, PCF85063ATL.
Building for it
A project is made for one toolchain, picked when you start it. For this board you can use one of them:
| 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 drives SPI panels only. |
| ESPHome | ESPHome has no driver for this controller. |
At a glance
| Part | Detail |

| MCU | ESP32-S3 Xtensa LX7 dual-core @ 240 MHz, 512 KB SRAM (+ 2-16 MB PSRAM on most modules) |
| Display | Solomon Systech SPD2010, 412 x 412 px, QSPI (quad SPI), 16-bit colour |
| Touch | Solomon Systech SPD2010 (touch half) (capacitive, I2C) |
| Backlight | GPIO 5, dimmable (PWM) |
| Memory | 16 MB flash, 8 MB octal PSRAM (N16R8) |
| Graphics library | GFX Library for Arduino |
Display pins
SPD2010 on QSPI (quad SPI): QSPI clock 40 MHz, host SPI2_HOST, RGB colour order, inversion off.
| Signal | Pin |
|---|---|
| SCK | GPIO 40 |
| D0 - D3 | GPIO 46, 45, 42, 41 |
| CS | GPIO 21 |
| RESET | TCA9554 pin 1 |
| Backlight | GPIO 5 |
Touch pins
SPD2010 (touch half): I2C address 0x53, 400 kHz, shares the display bus.
| Signal | Pin |
|---|---|
| SDA | GPIO 11 |
| SCL | GPIO 10 |
| INT / IRQ | GPIO 4 |
| RESET | TCA9554 pin 0 |
Also on the board
- I2C (GPIO 11 / 10) - SDA GPIO 11, SCL GPIO 10
- TCA9554 I/O expander at 0x20, driving the lines marked above
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-LCD-1.46/tree/main/example). The -B is the ESP32-S3-Touch-LCD-1.46 PCB sold with cover-glass options (SKUs 'without cover glass' / 'with protective cover glass' / 'widened'); its wiki links the 1.46 schematic and has no demo of its own, so the 1.46 GitHub repo was used.
Designing for it in LCD Wizard
- Choose Waveshare ESP32-S3-Touch-LCD-1.46B 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.handplatformio.ini- a project that builds for this board as it comes. - The SPD2010 (touch half) 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 412 x 412 px in either orientation, with LVGL 9 or LVGL 8.
The parts
SPD2010. Round 412x412 touch-and-display chip on QSPI. Turned, it is drawn a whole frame at a time, so it needs PSRAM.
SPD2010 (touch half). The touch half of the SPD2010 touch-and-display chip (Waveshare ESP32-S3-Touch-LCD-1.46).
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.
