Round 1.28inch touch LCD development board with 240×240 display and pin headers

LORDWORLD

LORDWORLD 1.28inch Round Touch LCD 240×240 65K RGB GC9A01 CST816S development board

SKU CH-ZG8T-2ECTF

A 1.28inch round touch display with 240×240 resolution and 65K colours, driven by GC9A01 and CST816S chips over SPI and I2C for Raspberry Pi, Pico, Arduino and STM32 projects

  • Sharp 240×240 round display with 65K colors
  • Capacitive touch via CST816S responds fast and lasts long
  • GC9A01 driver uses SPI to save IO pins
  • I2C touch interface keeps wiring simple on 1.28in board
  • Ready-to-run examples for Raspberry Pi, Pico, Arduino and STM32

1.28inch Round Touch LCD Development Board

This 1.28inch round LCD module delivers a 240×240 resolution with 65K colours for clear, colourful output. It integrates a GC9A01 driver and a CST816S capacitive touch controller, communicating over SPI and I2C to minimise IO usage. The board is designed for makers and engineers building embedded interfaces with Raspberry Pi, Pico, Arduino or STM32 platforms. Online resources and example code are provided to accelerate development.

Makers needing a compact circular touch display

Suits hobbyists and prototypers who want a small round touchscreen for wearable, instrument or IoT projects without designing a custom PCB. Not for buyers who need a larger viewing area, a rectangular form factor or a display without touch functionality. Projects requiring parallel RGB interfaces or higher colour depth should look at other modules.

GC9A01 driver with CST816S capacitive touch

The single specification that decides fit is the combined GC9A01 display driver and CST816S touch controller using SPI and I2C respectively. This pairing dictates the wiring, library support and pin count for your host controller. Verify that your target board supports both interfaces and that available libraries match your firmware environment before purchase.

Questions sur cet article

Will the 240×240 GC9A01 display work with my older Raspberry Pi Pico using SPI?

Yes, the GC9A01 driver communicates over SPI and the CST816S touch controller uses I2C, so the board works with older Raspberry Pi Pico boards without extra wiring.

How can I verify the 65K colour panel and capacitive touch are functioning after wiring?

Run the supplied example code for your controller; the screen should show a 240×240 test pattern in 65K colours and the CST816S should register single-finger taps immediately.

Does the package include jumper wires or a header for the SPI and I2C pins, or must I buy them separately?

The module ships with the round 1.28 inch LCD, GC9A01 driver and CST816S touch chip already soldered; connecting wires or headers are not included and must be sourced separately.
