0.71inch DualEye LCD Module

0.71inch DualEye LCD Module

0.71inch DualEye LCD Module is a 0.71inch dual-eye LCD module that uses two 160 × 160 pixel round IPS screens, with a built-in GC9D01 driver chip, communicating via an SPI interface. The module can be used with controllers such as ESP32, Raspberry Pi Pico, and Arduino for applications such as simulated electronic eyes or wearable devices.

Communication Protocol​

0.71inch DualEye LCD Module Communication Protocol Timing Diagram

This LCD uses a 4-wire SPI communication interface. SPI communication controls data transmission timing through the combination of clock phase (CPHA) and clock polarity (CPOL). This module uses SPI Mode 0: CPOL = 0 (idle low), CPHA = 0 (sampled on the first edge), with the most significant bit first and the least significant bit last.
