Overview
Introduction
The 0.71inch circular LCD module features an IPS display, with 160 x 160 pixels, equipped with an integrated GC9D01 driver chip, and utilizes SPI interface
communication. It is suitable for integration into controllers such as ESP32, Raspberry Pi Pico, Arduino, etc., and can be used in creative
applications like simulated electronic eyes or wearable devices.

LCD and its Controller
This LCD uses the built-in GC9D01 driver, with a resolution of 160×160. It has an internal GRAM and supports 12/16/18-bit data bus MCU interfaces, i.e.,
RGB444, RGB565, RGB666 three color formats, which are common RGB formats.

For most LCD controllers, the communication interface can be configured, including 8080 parallel, 3-wire SPI, 4-wire SPI, etc. This LCD uses a 4-wire SPI
interface, which saves GPIO pins and increases communication speed.
