0.71inch Double Eye Round LCD Display Module, 160×160 Resolution, SPI Interface, 65K Colors

Jargon buster

Plain-language definitions for the technical terms used above.

65K colors

65K colors means the display can show about 65,000 different colours, usually using 16-bit colour data. This affects how smooth photos, icons, and gradients look, and it also influences how much data your microcontroller must send to update the screen.

LCD

LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.

SPI

A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
