3.5" DSI Touchscreen for Raspberry Pi: The Compact HMI Solution Revolutionizing Industrial Interface Development

The OSOYOO 3.5" DSI touchscreen is the compact HMI solution for Raspberry Pi: a 3.5" IPS LCD that connects through the DSI connector, with 5-point capacitive touch and a physical resolution of 800×480. It is true plug-and-play — no driver installation needed. The IPS panel reduces glare and gives a wide, clear viewing angle from every direction.

Built for HMI, without the traditional HMI pain

• Program the UI in Python: drive the display directly through the DSI interface under Raspberry Pi OS and build interfaces with familiar high-level libraries such as Pygame and Tkinter — instead of learning a manufacturer's proprietary API and writing C/C++ HMI code.
• No GPIO consumed: unlike serial, SPI, or I2C HMI screens, the DSI connection leaves your GPIO resources free for sensors, relays, and control hardware.
• Compact 3.5" size: fits control panels, robotics interfaces, and portable prototypes where enclosure space matters.
• V3.0 engineering: compared with V2.0, the V3.0 is engineered for optimal performance without overheating, even during extended use — reliability and durability for power-intensive applications.
• Note: this V3.0 model is the 800×480 landscape, driver-free version.

Features

• 3.5" IPS LCD with 800 × 480 physical resolution, 24-bit colour and 60 Hz refresh rate
• Wide 170° viewing angle (85°/85°/85°/85°, left / right / up / down)
• 5-point capacitive touch (Raspbian OS supports 1 touch point)
• Plug and play — no driver needed
• Virtual resolution adjustable from 800 × 480 up to 1920 × 1080 on Raspberry Pi Legacy OS
• Strong anti-interference design, ultra-low power consumption, lossless long-distance signal transmission, auto-sleep function
• Compatible with Raspberry Pi OS, Ubuntu, RetroPie, OctoPrint, and more

What's in the box?

• 1 × 3.5" DSI touch screen
• 1 × 15-pin to 15-pin DSI FFC cable for Raspberry Pi 2/3/4
• 1 × 15-pin 1 mm to 22-pin 0.5 mm DSI FPC cable for Raspberry Pi 5
• 1 × screwdriver
• 1 × user guide manual

Setup in 3 steps

1. Flash your OS image (Raspberry Pi OS, Ubuntu, RetroPie, or OctoPrint) to a micro SD card (16 GB or larger) with Raspberry Pi Imager.
2. Connect the DSI cable: the 15-pin, 1 mm end goes into the screen's DSI port with the metal contacts facing up. Insert the SD card into the Raspberry Pi and connect the screen.
3. Power up and wait for the system to boot. No driver installation is needed.

Please note

• The DSI port of this 3.5-inch DSI V3.0 screen uses the same connector as the official Raspberry Pi 7-inch DSI screen, and it is compatible with the official DSI cable. Please pay attention to the contact points at the end of the cable.
• Adjusting the virtual resolution and the display orientation works on Raspberry Pi Legacy OS only; on Bookworm the DSI screen resolution cannot be adjusted. If you are using a Raspberry Pi 4, comment out the line #dtoverlay=vc4-kms-v3d in /boot/config.txt when adjusting the virtual resolution.
• An on-screen virtual keyboard can be added (matchbox-keyboard) on older Raspberry Pi OS versions; the latest Bookworm desktop comes with a virtual keyboard pre-installed.
• Brightness can be adjusted with echo 100 > /sys/class/backlight/rpi_backlight/brightness (replace 100 with any value from 0 to 255) or with brightnessctl. If brightness adjustment fails, check for the line disable_touchscreen=1 in /boot/config.txt and comment it out.
• Make sure your micro SD card has enough space for the system image, and do not touch your Raspberry Pi board when the power is on or when your hands carry a static charge (discharge static by touching a metal faucet or tap).
