Waveshare ESP32-S3-LCD-0.85
0.85" 128x128 IPS LCD (GC9107, SPI), ES8311 audio, TF card.
Building for it
A project is made for one toolchain, picked when you start it. All three can drive this board:
| 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 | No compiler to install, and the panel can join Home Assistant as real entities. Start a project |

Display pins
GC9107 on SPI (4-wire serial): SPI clock 40 MHz, host SPI2_HOST, BGR colour order, inversion on.
| Signal | Pin |
|---|---|
| SCK / CLK | GPIO 38 |
| MOSI / SDA | GPIO 39 |
| CS | GPIO 21 |
| DC / RS | GPIO 45 |
| RESET | GPIO 40 |
| Backlight | GPIO 46 |
Also on the board
- I2C (GPIO 42 / 41) - SDA GPIO 42, SCL GPIO 41
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-LCD-0.85). The docs call it a 'capacitive LCD' and xiaozhi defines TOOUCH_INT 48 / TOOUCH_RST 47, but the schematic's LCD FPC has 12 pins and no touch lines, GPIO48 is the WS2812 data line and no demo reads touch - recorded touch null.
Designing for it in LCD Wizard
- Choose Waveshare ESP32-S3-LCD-0.85 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 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 128 x 128 px in either orientation, with LVGL 9 or LVGL 8.
The parts
GC9107. Small square panel, e.g. the ESP32-C3-LCDkit.
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.
