CM5 to Pi 5 Adapter

Got a Compute Module 5? Cool. Got a Pi 5? No? Want to turn your CM5 into a Pi 5? Yes, yes you do! This adapter board from Waveshare converts a Raspberry Pi Compute Module 5 into the footprint and connector style of a Raspberry Pi 5, including a full 40-pin GPIO header, USB ports, Gigabit Ethernet, PCIe interface, PoE header, RTC header, MicroSD slot, fan header, power button and more. Some things are shifted around a bit, such as the dual DSI/CSI ports, but the majority of features mirror the Pi 5 layout. An interesting addition is the audio interface, which uses a little included module to provide a 3.5mm jack output. We can't guarantee this board will work in all Raspberry Pi 5 cases (as some hug the board very closely), but it should work with most. CM5 not included Important stuff Because it's not going to be exactly like a Raspberry Pi 5 of course...

* Do not plug or unplug any device other than USB and HDMI when the device is powered on

* USB-C can be used as a USB SLAVE interface to flash images

* Onboard default 2 USB 3.2 Gen1 port

* Supports 4 screens to display different contents, adds MIPI DSI driver, regardless of whether a screen is connected, the system will default to connect, the screen will display in split-screen mode (related to the system version)

* The onboard BOOT button, you can press the BOOT button before powering on, and connect to the computer through USB0-C to let the device enter the flashing mode

* Do not connect other devices when using USBC for flashing. Insufficient power supply will cause the device to be unrecognised

* The USB2.0 ports have a total maximum power output of 2A, and the USB3.0 ports have a total maximum power output of 2A
