1.9-inch IPS LCD Module
This 1.9-inch IPS LCD module delivers a 170 × 320 RGB resolution with 262K display colours. It is designed for developers and hobbyists building compact visual interfaces on Arduino, Raspberry Pi or STM32 platforms. The onboard ST7789V2 controller handles rendering directly on the panel.
SPI interface and 3.3 V / 5 V logic
The display communicates through a four-wire SPI bus, minimising the GPIO pins required from the host board. An onboard voltage translator accepts either 3.3 V or 5 V logic levels, provided the supply voltage matches the logic voltage. This compatibility simplifies integration across common 3.3 V and 5 V development boards.
IPS panel maintains colour at wide angles
The IPS screen preserves colour accuracy and contrast across broad viewing angles, so the image remains readable even when the module is mounted off-centre. Continuous SPI updates are handled by the embedded controller without flicker during sustained animation or data logging. The 27.3 × 51.2 mm module footprint fits tight enclosures.

Questions about this item
What does the 170×320 resolution look like on a 1.9 inch screen?
The 1.9 inch IPS panel packs 170 horizontal by 320 vertical pixels into a 22.70 × 42.72 mm active area, giving a sharp, colour-rich image with 262K colours.
How does the SPI interface limit the display's refresh rate in practice?
SPI keeps pin count low and works with Arduino, Raspberry Pi and STM32 boards, but the serial bus caps the maximum frame rate well below what a parallel or RGB interface could sustain.
What mounting space does the 27.3 × 51.2 mm module need?
The PCB measures 27.3 mm wide by 51.2 mm long, so allow at least that footprint plus clearance for the header pins and any enclosure bezel.
