Introduction

The OSOYOO 3.5-inch DSI touchscreen is designed to plug straight into the Raspberry Pi’s MIPI DSI ribbon connector. It offers a 480×800 portrait IPS display with capacitive touch, suitable for embedded HMI panels, portable Pi-based dashboards, smart-home controllers, maker and education projects. The screen connects with a single DSI ribbon cable — no HDMI and no GPIO header required.

Under the Raspberry Pi desktop, the display supports a brightness slider, display rotation, and touch that rotates together with the display. This product requires driver installation (it is not a driverless plug-and-play display); after installing the driver you get a complete desktop touch experience. For step-by-step usage see Using with Raspberry Pi and Using with ESP32‑P4.

Key Features

• 3.5-inch IPS display, 480×800 resolution, wide viewing angle
• 300 cd/m² brightness, glass panel surface
• Native MIPI DSI connection — no HDMI, no USB data cable required
• Capacitive touch, smooth and responsive (multi-touch support depends on OS and application)
• Compatible with current Raspberry Pi boards with a DSI connector: Pi 5 / 4B / 3B+ / 3B / 2B, and CM4 / CM5 on carrier boards
• Desktop support for brightness slider, display rotation, and touch-follows-rotation
• Powered from the Raspberry Pi DSI connector — no separate power adapter required
• Supports Raspberry Pi OS Bookworm / Trixie
• Can also be used with an ESP32‑P4 development board
• Compatibility: for Raspberry Pi boards with a DSI connector. Pi 4B / 3B+ / 3B / 2B have a single 15-pin DISPLAY port; Pi 5 has two 22-pin DISP0 / DISP1 ports (needs a 22-pin to 15-pin cable; DISP1 by default, add ,dsi0 when using DISP0); Compute Module (CM4 / CM5) depends on the carrier and requires manual config.txt setup; also for some ESP32-P4 IO board

Specifications

About touch: under the official Raspberry Pi OS, this display works as a single-touch screen; whether multi-touch and gestures work depends on the OS version and the specific application — some applications handle single touch only. If your project needs reliable multi-touch, please verify on your target OS and application first.

Package Contents

• 1 × OSOYOO 3.5-inch DSI touchscreen (panel and PCB assembled)
• 1 × DSI FPC ribbon cable (15-pin; for Pi 5 / CM5 use a 22-pin to 15-pin cable)
• 1 × 5V power cable (to supplement power when DSI power is insufficient)
• 1 × standoff / screw mounting kit
• 1 × quick-start card

Power Supply

In normal use the display is powered through the DSI ribbon cable by the Raspberry Pi; no extra wiring or power adapter is needed for a standard setup. Please use an adequate genuine power supply for the Raspberry Pi so that display and touch operate reliably.

The PCBA also provides a 5V / GND backup power header, and a power cable is included. In some cases where the DSI connector cannot deliver enough power (e.g. an under-rated adapter, a long power cable, or heavy USB peripheral load on the Pi), use the included cable to supplement power: connect the header’s 5V to the Raspberry Pi 5V pin and GND to the Raspberry Pi GND pin.

Note: insufficient power may cause flicker, unresponsive touch, or a blank screen. The external supply must be 5V; do not reverse the polarity or exceed the voltage, or the board may be damaged.

Interface Definition

The interface location is shown below; please connect against the actual product.

• DSI — MIPI DSI FPC connector, connects to the Raspberry Pi DISPLAY / DSI port.
• 5V / GND — backup power header; if DSI power is insufficient, use the included cable to connect its 5V to the Raspberry Pi 5V pin and GND to the Raspberry Pi GND pin.

Safety Notes

• Always power off before connecting / disconnecting the ribbon or jumpers.
• The panel surface and ribbon are fragile — avoid bending, pressing, or dropping.
• Use in a dry, clean environment; avoid liquid ingress and electrostatic discharge.
• Use an adequate, compliant power supply; do not exceed the rated range.
• Do not disassemble the module unless you are a professional.
