2 Inch LCD Screen for Raspberry Pi and Embedded Applications
Ultra-compact 2.0" TFT/IPS display module engineered for Raspberry Pi, Arduino, and embedded IoT systems. Featuring crisp 240×320 resolution, high-speed 4-wire SPI bus with minimal GPIO footprint, optional capacitive/resistive touch, and comprehensive Linux driver support.
Product Overview & Compact Embedded Versatility
Engineered specifically for space-constrained industrial electronics, the 2.0 inch LCD screen provides clear visual feedback without burdening microcontroller memory or occupying excessive Raspberry Pi 40-pin header space.
Why Engineers Choose the 2.0" Form Factor
While micro displays under 1.5 inches often compromise textual legibility and larger 3.5" to 7.0" panels demand parallel RGB or HDMI headers, the 2.0-inch module strikes the golden ratio: offering 240×320 pixels at approximately 200 PPI with a lightweight footprint that fits inside standard 35mm DIN-rail modules, handheld test probes, and portable instrumentation.
Seamless Raspberry Pi Ecosystem Integration
Fully compatible with Raspberry Pi 5, 4 Model B, 3B+, Zero 2 W, and Pico / RP2040. Out-of-the-box support includes Linux frame-buffer overlays (FBTFT / DRM), Python Pillow/Pygame libraries, and hardware-accelerated LVGL graphics stacks.
Core Engineering Features
Balanced electrical and physical properties designed to expedite prototyping and endure OEM deployment.
Compact TFT & IPS Architecture
Ultra-lightweight footprint engineered for handheld tools and DIN-rail IoT enclosures. Reduces overall mechanical volume while preserving 30.60 × 40.80 mm of readable graphical space.
240×320 High-Resolution Color
Vibrant 262K/65K RGB color depth with true IPS wide viewing angles. Zero color-inversion even at steep angles, paired with factory anti-glare polarization for crisp readability under factory lighting.
Raspberry Pi 4-Wire SPI Bus
Conserves critical GPIO pins for sensors, relays, and fieldbus transceivers. Includes integrated level-shifter circuitry supporting both 3.3V logic (Raspberry Pi/STM32) and 5V logic (Arduino Uno/Mega).
Touch Integration Options
Select between non-touch for compact telemetry, Projected Capacitive (PCAP) multi-touch with I2C interface, or rugged 4-wire resistive touch for gloved industrial maintenance environments.

How to Choose a 2 Inch LCD Screen for Raspberry Pi
Four critical engineering checkpoints to evaluate prior to finalizing your component bill of materials (BOM).
Interface & GPIO Budget
Determine whether 4-wire SPI fits your GPIO budget. SPI requires only CS, DC, SCL, SDA, and RST (5 pins), leaving remaining pins open for I2C sensors and industrial relays.
Display Tech & Angles
Opt for IPS active matrix if operators view the display from multiple angles or if high color fidelity is critical. Standard TN panels can be specified when cost reduction is the dominant factor.
Touch Integration Needs
Choose non-touch for compact telemetry readouts. Choose PCAP multi-touch for modern smartphone-like swipe UI, or resistive touch for stylus & heavy-glove operating environments.
Software & OS Stack
Confirm driver support: ensure the display uses proven controllers like ST7789V which are natively supported in recent Linux kernels via Device Tree overlays and CircuitPython/LVGL.
