M5Stack Cardputer 1.14" specifications
The M5Stack Cardputer 1.14" is a 1.14" 240×135 display board by M5Stack, built around the ESP32-S3 (ESP32-S3FN8 (StampS3 module) module) running at 240 MHz. The panel uses a ST7789 (SPI) controller over SPI, without a touchscreen. Memory: 8 MB flash, no PSRAM; wireless: Wi-Fi and Bluetooth. In LCD Ultra Pro you can design its UI visually at the exact resolution; a ready-made display driver for the Arduino export is not available yet, so the export contains the LVGL UI code for your own project.

Free GPIOs and connectors
These GPIOs are not used by the display, touch or on-board peripherals, so you can wire your own sensors, buttons or relays to them.
| Pin | Capabilities | Note |
|---|---|---|
| GPIO 0 | GPIO, BOOT | Boot button |
| GPIO 1 | GPIO, ADC | Grove port, presumably free |
| GPIO 2 | GPIO, ADC | Grove port, presumably free |
LVGL support in LCD Ultra Pro
| Driver status | Driver not available yet |

Pick this board in the editor and the canvas matches its exact resolution and shape. Build the interface with widgets, add events without code, try it in Live Preview, then export it as LVGL UI code. See the documentation for the workflow.
Frequently asked questions
What is the resolution of the M5Stack Cardputer 1.14"?
240×135 pixels on a 1.14" screen, driven at 16-bit colour depth.
Which display controller and interface does it use?
ST7789 (SPI) over SPI.
Does the M5Stack Cardputer 1.14" have a touchscreen?
No. has a built-in 56-key QWERTY keyboard instead
Which ESP32 chip and how much memory does it have?
ESP32-S3 (ESP32-S3FN8 (StampS3 module)) at 240 MHz, 8 MB flash, no PSRAM.
Which GPIOs are free for my own sensors or relays?
3 GPIOs are free: GPIO 0, GPIO 1, GPIO 2.
Can I use LVGL on the M5Stack Cardputer 1.14"?
Yes, with your own display driver setup. In LCD Ultra Pro you can design the UI at the board’s exact resolution and export the LVGL 8.4 UI and event code; a ready-made display driver for this board is not included yet, so you call ui_init() from your own LVGL project.
