Who it fits

Key specs explained

CM5 support, 4 modules

This board holds four Raspberry Pi Compute Module 5 units. You get a compact cluster for parallel tasks. It is not for older CM4 modules. This setup suits developers who need multiple nodes for testing or learning. You save desk space compared to separate single-board computers. It is a specialized solution for hobbyists building distributed systems rather than a general-purpose desktop.

Mini-ITX form factor

The board follows the standard Mini-ITX size. This allows you to mount it in a 10-inch server rack or standard case. You gain flexibility in how you house the hardware. This is useful for home labs or small office setups. It is not a tiny stick PC. You need a case that fits this specific size to protect the components and manage airflow effectively.

2.5 GbE + 1 GbE

Each module has a 2.5 Gigabit and a 1 Gigabit Ethernet port. You get faster local network speeds for data transfer. This is quicker than standard 1 GbE connections. It benefits users moving large files between modules. You should check your router supports these speeds. This is better for cluster communication than basic home networking gear.

Dual 12-20V power input

The board accepts two power inputs for redundancy. If one source fails, the other can keep the system running. This increases reliability for always-on projects. You need compatible power supplies for this feature. It is more robust than single-input devices. This is important for clusters where downtime is disruptive. You ensure continuous operation for critical tasks.

M.2 NVMe support

Each module can use an M.2 NVMe drive. You get fast storage for the operating system and data. This is much quicker than SD cards. You benefit from better load times and file access. It is a standard feature in modern mini PCs. This ensures your cluster performs well under heavy workloads without bottlenecking.

Design and build details

The DeskPi Super4C follows a standard Mini-ITX form factor. According to the listing, the board measures 6.77 inches in length, 6.89 inches in width, and 0.75 inches in height. These dimensions allow you to mount the unit in a 10-inch rack or server cabinet. You can use a compatible case to secure the assembly in a standard 10-inch server cabinet. This layout suits users who need a compact, stackable cluster for edge computing or lab environments.

The build focuses on structural stability and power redundancy. The design supports four CM5 modules simultaneously. Each slot provides independent power control. This separation helps isolate issues if one node fails. The board includes dual 12-20V power inputs. This redundancy increases reliability for continuous operation. An integrated E/S/P/32 chip enables remote management of the entire cluster. You can monitor voltage and current using two INA3221 sensors.

Connectivity is dense but organized. Each channel features a 2.5 GbE port and a 1 GbE port. M.2 M-Key 2280 NVMe slots are available for each module. Extended GPIOs and a USB 2.0 programming port assist with eMMC management. The package includes the board and a DC 19.0V 4.73A power supply. The finish is utilitarian, prioritizing function over aesthetics. You get a straightforward platform for building a multi-node Raspberry Pi cluster without complex wiring.

Setup and daily operation

Setting up this cluster requires planning your power and network connections. The listing specifies a dual 12-20V power input with redundancy. You connect the included DC 19.0V 4.73A power supply to this system. This dual input design allows you to maintain operation if one power source fails. Each of the four channels has independent power control. This means you can manage energy usage for each Compute Module 5 separately. The board also features an integrated E/S/P/32 chip. This component enables remote management of the entire cluster. You can monitor system health without being physically present at the unit.

Networking is straightforward for each module. You get two network ports per channel: a 2.5 GbE port and a 1 GbE port. This setup supports high-speed data transfer for your applications. Storage is handled via M.2 M-Key 2280 NVMe drives for each CM5 module. This allows fast boot times and quick data access. You can also use the extended GPIOs and USB 2.0 programming port for eMMC management if needed. Monitoring is built into the hardware. Two INA3221 sensors track voltage and current in real time. This data helps you ensure the system runs within safe parameters. The package includes the board and the power supply. You must provide the Compute Module 5 units and storage drives yourself. This configuration is ideal for developers running parallel tasks or testing distributed systems.

Before you buy this cluster

This board is a specialized tool, not a standalone computer. You must purchase four Raspberry Pi Compute Module 5 units separately. The listing explicitly states it is not compatible with the older CM4 modules. Check your existing inventory before ordering. You will also need networking cables for the dual 2.5GbE and 1GbE ports on each channel. Storage requires M.2 NVMe drives for each module. The Mini-ITX form factor allows rack mounting in a 10-inch cabinet. You may need a separate case for that. This setup suits developers building test clusters. It does not replace a single-purpose mini PC for daily desktop tasks. Consider if you truly need four nodes. The dual power input adds reliability but requires careful cable management. Plan your workspace for the width and height dimensions. This is a hardware foundation, not a ready-to-use appliance.

Check before you buy

• Confirm you have four CM5 modules, not CM4.
• Check if you need a 10-inch rack case.
• Verify you have M.2 NVMe drives for storage.
• Ensure your network supports 2.5GbE connections.
