5inch Touch Screen Expansion for Raspberry Pi CM4

This all-in-one expansion board breaks out your Raspberry Pi Compute Module 4 with a buffet of useful IO and connection options, whilst also providing a 5″ 800×480 5-point capacitive touch screen!

The rear of the board provides a huge list of useful breakouts for your CM4 board:

  • M.2 slot (for NVMe M-Key SSD)
  • 4x USB 2.0
  • Gigabit Ethernet
  • Dual MINI CSI-2 Ports (15-pin 1mm pitch) for Raspberry Pi Camera Modules
  • RTC with backup battery socket (CR1220)
  • 40-pin GPIO header
  • PoE Header (PoE HAT required for PoE operation)
  • BOOT switch
  • Micro-SD card slot (when using Lite CM4 only)
  • USB-C power/programming port
  • Full-size HDMI port (supports 4K 30FPS)
  • 4-pin fan header (ideal fan option here!)
  • System function selector pads
  • I2C BUS selection pads
  • RTC interrupt toggle pads
  • VREF selection pads
  • Indication LEDs

All of this along with a 5″ display with a respectable 800×480 resolution with 5-point capacitive touch!

We recommend fully reading the product wiki before purchasing to ensure a full understanding of the feature set and any limitations/compatibility for your intended project or usage.

Notes

  • The USB SLAVE interface is used to burn the image and cannot be used as an OTG interface.
  • In normal use, it is necessary to provide at least 5V 2.5A power supply for CM4. Otherwise, there may be problems such as automatic shutdown and frequency reduction
  • Onboard default 4-way USB 2.0 interface.
  • Supports PoE via 4-pin header, additional PoE HAT is required for PoE
  • The display requires a driver
  • Do not plug and unplug any device except USB and HDMI while the baseboard is working
  • If the fan needs to be replaced, please confirm the fan voltage and then power on
