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 What's Onboard? * CM5 socket * Suitable for all variants of Compute Module 5. * 40-pin GPIO interface * Suitable for connecting a range of HAT and HAT+ modules. * Power supply / programming * Supports a 5 V / 5 A power supply and can also be used for eMMC flashing. * STAT LED * Dual-colour LED status indicator. * PSW power button * Long press to force a power-off; short press to perform a soft power-off or power-on. * PCIe interface * For connecting a range of PCIe expansion boards. * RTC battery header * For connecting an external RTC battery to maintain real-time clock operation. * BOOT button * Press before powering on, then release after powering on to enter flashing mode. * 2 × Micro HDMI ports * Supports up to 4K output. * Extended audio interface * Provides audio output via USB and includes an audio adaptor for connecting 3.5 mm headphones or a microphone. * 4-pin PoE header * For connecting a PoE module. * Dual MIPI interfaces * For connecting DSI displays or CSI cameras. * 4-pin JST-SH PWM fan header * For connecting a 5 V cooling fan. * 2 × USB 2.0 ports * 2 × USB 3.2 Gen 1 ports * Supports simultaneous read and write operations at speeds of up to 5 Gbps. * Gigabit Ethernet RJ45 port * Supports 10/100/1000 Mbps network connections. * TF card slot * For use with a TF card containing a pre-installed image (Lite variant only). * IO-VREF selection * Selects the CM5 I/O logic level: 3.3 V (default) or 1.8 V. * Other function pins * For hardware disable functionality or write protection.
