Round LCD HAT

Round LCD HAT is a 1.28-inch display expansion board module of 240×240 resolution, 65K RGB colors, clear and colorful displaying effect, with a joystick, designed for Raspberry Pi to expand its engagement via SPI communication by providing standard 40 pins GPIO interface. The Round LCD HAT comes with an embedded GC9A01 Driver and SPI Interface that minimize the required IO pins. It is designed with a 5-input Joystick that will be internally connected to the Round LCD HAT via a stackable GPIO connector header.

Features

  • 240 x 240 Resolution
  • 32.4mm Diameter
  • IPS Display Panel
  • GC9A01 Driver
  • Raspberry Pi series compatibility
  • 4-wire SPI Communication
  • Standard Raspberry Pi 40 Pins GPIO
  • 4 directions + attached band Central press button Joystick Control

    • Specifications

  • Operating Voltage - 3.3 V
  • Pixel Size - 0.135 × 0.135mm
  • Board Dimension - 56mm × 65mm
  • Pixels - 240×240 resolution
  • Display Colour - 65K RGB
  • Driver - GC9A01
    • Pico 1.14 LCD HAT
