2-inch IPS LCD Module

This 2-inch IPS LCD module delivers a 240×320 RGB resolution with 262K colours. It uses an SPI interface driven by the ST7789V controller and operates at 3.3V or 5V. The compact board measures 58×35 mm with a 23.4 mm square active area.

Makers needing a small SPI screen

Developers adding a display to Raspberry Pi, Jetson Nano, Arduino or STM32 projects will find the four-wire SPI connection straightforward. Builders who require a parallel RGB interface, higher resolution or a larger viewing area should consider other modules.

SPI interface with minimal GPIO

The display communicates over SPI, keeping the GPIO requirement low for resource-constrained microcontrollers. This single interface choice determines whether the module fits a given design.

Questions about this item

Does the 2‑inch IPS panel draw enough current to heat up or make noise during continuous SPI operation?

The module runs at 3.3 V over a low‑speed SPI bus with minimal GPIO toggling, so power draw stays in the milliwatt range and produces no audible noise or noticeable heat.

Which host pins and voltage level must my board provide to drive the ST7789V controller?

You need a 3.3 V SPI master with chip‑select, clock, data and data/command lines; the display tolerates 5 V logic but is specified for 3.3 V operation.

Will the 240×320 RGB pixel array and 0.0975 mm pitch match the frame‑buffer timing of an older Arduino or STM32 board?

Yes — the ST7789V accepts standard SPI command sequences and the 240 × 320 resolution fits within the memory limits of most legacy 8‑bit and 32‑bit microcontrollers.
