5" 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" 800x480 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 2242-size NVMe M-Key SSD)

* Not compatible with the Raspberry Pi SSD (as it's only 2230 size)

* 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 800x480 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
