CM4 Mini vs CM5 PoE IO Board
Networking capabilities
The Waveshare Compute Module 5 PoE IO Board offers a distinct advantage for network setups. It provides both network connection and power supply through a single cable. This PoE feature simplifies installation by reducing cable clutter. In contrast, the Waveshare Raspberry Pi CM4 Mini Base Board includes an RJ45 Gigabit Ethernet port. It connects via standard Ethernet but does not list Power over Ethernet support in its specifications. If you need to power the device over the network cable, the CM5 board is the better choice. Otherwise, both provide standard wired connectivity.
Storage options
Both boards support M.2 slots for storage, allowing for fast NVMe SSD booting. The Waveshare Compute Module 5 PoE IO Board explicitly mentions faster reading and writing speeds compared to TF cards, highlighting its efficiency for system files. The Waveshare Raspberry Pi CM4 Mini Base Board also includes an M.2 slot and a Micro SD Card Slot. It does not explicitly detail the speed benefits of the M.2 interface in the provided text, though it supports it. Both platforms offer flexible storage configurations, making this a tie for most users who prioritize NVMe performance.
Display interfaces
The Waveshare Raspberry Pi CM4 Mini Base Board features specific display connectors, including CSI and DSI interfaces. However, it notes that only the DSI0 interface is connected, while DSI1 is not. This limits dual-display DSI setups. The Waveshare Compute Module 5 PoE IO Board lists MIPI connectors onboard. It does not specify the number of active lanes or interfaces in the provided data. Both boards support HDMI output. If you rely on specific DSI display configurations, the CM4 board’s limitation is clear. The CM5 board’s exact MIPI capabilities remain less defined in the available specs.
Physical dimensions
Size matters for integration into end products. The Waveshare Raspberry Pi CM4 Mini Base Board has defined outline dimensions of 85x56mm. It is described as a mini base board, fitting the compact nature of the CM4 module. The Waveshare Compute Module 5 PoE IO Board does not list specific length, width, or height measurements in the provided data. You cannot compare the physical footprint accurately without these numbers. The CM4 board’s dimensions are explicitly stated, aiding in enclosure design. For the CM5 board, you would need to check other sources for size details.
Module compatibility
Each board is designed for a specific compute module generation. The Waveshare Raspberry Pi CM4 Mini Base Board is suitable for the Compute Module 4 Lite and EMMC series modules. It uses a standard CM4 socket. The Waveshare Compute Module 5 PoE IO Board is compatible with all variants of the Compute Module 5. It uses a standard CM5 socket. You cannot mix these modules and boards. The CM5 board supports the newer generation of modules. If you already have a CM4, you must use the CM4 board. If you are building with a CM5, the PoE board is the required platform.
Which Waveshare Mini PC Base Should You Choose
Users needing single-cable power and data
The Waveshare Compute Module 5 PoE IO Board provides both network connection and power supply through a single cable. This feature simplifies installation by reducing cable clutter. You benefit from a cleaner setup, especially if you are integrating the board into end products where space is limited. The PoE capability is a distinct advantage for your network requirements.
Users wanting faster NVMe boot speeds
This board supports booting from an NVMe Solid State Drive. You get faster reading and writing speeds compared to a TF card slot. This greatly improves the efficiency of your system or file operations. If you need quick boot times and high performance for your Compute Module 5, the NVMe support makes this the better choice for your workflow.
Users with existing CM4 modules
The Waveshare Raspberry Pi CM4 Mini Base Board is designed specifically for the Compute Module 4. It features a standard CM4 socket and a color-coded 40-pin GPIO header. It supports the CM4 Lite and EMMC series modules. If you already own a CM4, this board is the compatible evaluation platform. It includes a Micro SD card slot for your storage needs.
