The Grove 1.22 Inch IPS Display is a compact Grove display module built around a 240x240 IPS panel, the ST7789 driver IC, and a simple serial SPI connection using SCK and SDA. It displays up to 65k RGB colors with a wide viewing angle, making it suitable for small UI panels, DIY weather stations, handheld projects, smart home displays, educational builds, and industrial control interfaces. The module supports 3.3V or 5V input and uses the Grove 4-pin connector to simplify wiring. Seeed provides an open-source ST7789 driver library and example code for quick Arduino-based development.

It uses a simplified serial SPI connection that requires SCK and SDA signals, making wiring easier for compact microcontroller projects. What power supply should I use? The board accepts 3.3V or 5V input, so use a power source within that range. Can it be used outside normal room temperature? The display is rated for -20°C to 70°C, but normal room-temperature operation is recommended for best long-term performance. What can cause incorrect colors? Incorrect initialization, wrong color values, loose wiring, or a faulty connection can cause color issues. Check the code configuration and connections first.
