Waveshare ESP32-C6-LCD-1.54
1.54" 240x240 IPS LCD (ST7789, SPI), ES8311 audio, TF card, QMI8658.
Building for it
A project is made for one toolchain, picked when you start it. For this board you can use 2 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 | lvgl_micropython has no build for this chip. |
| ESPHome | No compiler to install, and the panel can join Home Assistant as real entities. Start a project |

Also on the board
- I2C (GPIO 8 / 7) - SDA GPIO 8, SCL GPIO 7
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-C6-Touch-LCD-1.54 (commit a4f92a91d0c94100a2bd16ce36d5f83652ad1f3b)). Shares the PCB and docs page with ESP32-C6-Touch-LCD-1.54; Waveshare says the only difference is the touch panel (CST816 at 0x15, INT GPIO5, on the Touch version only).
Designing for it in LCD Wizard
- Choose Waveshare ESP32-C6-LCD-1.54 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.
- Screens are designed for 240 x 240 px in either orientation, with LVGL 9 or LVGL 8.
The parts
ST7789. Excellent colour and tolerates 80 MHz SPI. Many modules have no CS pin - tie it low and set CS to -1.
ESP32-C6. No PSRAM. SPI displays only in practice.
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.
