With a 240×320 pixel resolution, it’s suitable for handheld instruments, sensor dashboards, and simple control panels. The display uses the proven ILI9341 driver, so it works with a wide range of Arduino libraries right out of the box.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eScreen Size\u003c\/td\u003e\n\u003ctd\u003e2.4 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e240 × 320 pixels\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDriver IC\u003c\/td\u003e\n\u003ctd\u003eILI9341\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTouch Type\u003c\/td\u003e\n\u003ctd\u003eResistive (4-wire)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eSPI (4-wire)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3 V (5 V tolerant pins)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003eA portable weather station showing temperature, humidity, and forecasts on a colour screen\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eA touch-controlled menu interface for an IoT home automation controller\u003c\/li\u003e\n  \u003cli\u003eA simple graphics demo or mini arcade game using Adafruit GFX library\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-soil-sensor-data-logger\"\u003eA sensor data logger with real-time scrolling graphs\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe display is designed for 3.3 V logic but the signal pins tolerate 5 V, so it works directly with Arduino Uno, Mega, and Nano. It pairs easily with the Adafruit_ILI9341 and MCUFRIEND_kbv libraries. The touch controller shares the SPI bus, requiring two extra analog pins for X and Y coordinate readout.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 3.3 V on the Uno, GND to GND. Link SCK to pin 13, MOSI to pin 11, CS to pin 10, DC to pin 9, and RESET to pin 8. Touch pins T_CLK, T_CS, T_DIN, T_DO, T_IRQ can go to analog pins A0–A4. Keep wiring short and avoid placing the module near high-current circuits to prevent touch glitches.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Raspberry Pi?\u003c\/summary\u003e\u003cp\u003eYes, with a level shifter for the 5 V pins. You can drive it via SPI using the same ILI9341 driver and the fbtft kernel module. Touch control works over the analog interface with an external ADC.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhich library should I use for Arduino Uno?\u003c\/summary\u003e\u003cp\u003eUse the MCUFRIEND_kbv library for quick setup. Include the Adafruit_GFX library for drawing shapes and text. For touch, a lightweight routine reading the analog pins works without additional libraries.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the touchscreen need calibration?\u003c\/summary\u003e\u003cp\u003eResistive touch panels can drift slightly. A simple calibration sketch mapping raw X-Y values to screen coordinates is recommended. Once calibrated, touch accuracy is within a few pixels.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
