WaveShare 3.5inch DPI LCD 640x480 Capacitive Touch portable monitor

SKU CH-K5KR-TK9WH

A 3.5 inch capacitive touchscreen monitor with 640 by 480 resolution, 262K colours and a 60 Hz refresh rate, connecting via the 40 pin GPIO interface for Raspberry Pi boards

  • CPU TypeOther
  • 5-inch IPS display gives 640 x 480 hardware resolution
  • DPI666 interface drives the panel at up to 60 Hz
  • Capacitive touch supports five simultaneous points through I2C
  • Toughened glass cover reaches 6H hardness for scratch resistance
  • Low-power design connects directly to the 40-pin GPIO header

Compatible Raspberry Pi models

This 3.5 inch portable monitor connects directly to the 40 pin GPIO header on Raspberry Pi 4B, 3B+, 3B, 3A+, Zero W, Zero 2 W and Zero 2 WH. It draws power and video through the same interface so no separate cables or adapters are required. The display is ready to use with Raspbian and Kali Linux systems.

Touch-enabled projects and embedded builds

Developers adding a capacitive touch interface to a Raspberry Pi will benefit from the five point touch panel and toughened glass cover rated at 6H hardness. The low power design suits battery operated or enclosed devices. Builders who need HDMI, DisplayPort or USB video input should choose a different monitor.

640 by 480 DPI666 panel at 60 Hz

The screen delivers a hardware resolution of 640 by 480 pixels driven through the Raspberry Pi DPI666 interface with 262K colours and a 60 Hz refresh rate. This fixed specification determines whether the panel matches your project's visual requirements.

Questions about this item

Does the 60 Hz DPI666 interface keep up with fast motion on the 640x480 panel?

The DPI666 interface drives the 3.5-inch LCD at 60 Hz with 262 K colours, matching the panel's native refresh rate for smooth video and UI animation.

How hot does the toughened glass cover get after hours of continuous use?

The display is described as a low-power solution and draws its supply from the Raspberry Pi GPIO, so heat stays minimal even during all-day operation.

Which Raspberry Pi models provide the 40-pin GPIO and I2C lines this screen needs?

Compatible boards include Raspberry Pi 4B, 3B+, 3B, 3A+, Pi Zero W, Zero 2 W and Zero 2 WH, all of which expose the required 40-pin GPIO and I2C interfaces.
