Specifications side by side

Comparing the Radxa SBC Lineup

Radxa splits its lineup between standalone boards and modular add-ons. If you need primary computing power, boards differ by processor architecture, memory, and networking speeds. The Radxa Rock 5 Model B provides an RK3588 processor, 8GB memory, and 2.5GbE networking for high-throughput setups. For edge computing and automation, the Radxa Rock 4D delivers 6GB memory with 6TOPS AI capability for industrial workloads.

The remaining options are expansion hardware designed for specific deployments. If you want to eliminate separate power cables, the Radxa 25W PoE+ HAT delivers power and active cooling over an Ethernet connection. For storage builds, the Radxa Penta 5-Port SATA HAT connects up to five SATA drives to compatible host boards.

Where the Radxa Lineup Fits

Radxa suits you if you need compact hardware for networking, local AI processing, or multi-drive storage. The range spans from 3.5-inch square boards to larger footprints, offering 4GB to 8GB memory, 2.5GbE networking, and 8Kp60 video. Modular accessories add active cooling, 25W PoE power, or five SATA drive connections.

Be aware of the gaps across the 7 products. None of the listed boards include wireless networking specifications. You get no built-in power supplies, and storage expansion demands external ATX or 12V DC input. The lineup also provides no integrated display panels or built-in lighting options.

How to Choose the Best Radxa Board

1. Assess Neural Processing Capabilities

   Check computing power and neural acceleration specs before selecting a board. General utility tasks run smoothly on standard multi-core processors, but on-device machine learning requires dedicated hardware acceleration. Look for listed TOPS ratings to gauge neural execution speed. If your setup runs automated computer vision or local inference workloads, select the Radxa Rock 4D 6GB Single Board Computer for its integrated 6TOPS NPU. Standard media tasks do not need hardware AI acceleration, making basic multi-core silicon the appropriate choice instead.

2. Check Ethernet Port Bandwidth

   Network interface speed directly dictates data transfer rates across local networks. Basic embedded tasks, sensors, and lightweight servers run fine on standard Gigabit Ethernet. However, media streaming servers, high-throughput routing, and heavy multi-stream pipelines benefit from upgraded network interfaces. You should check whether a board specifies Gigabit or 2.5GbE connectivity. The Radxa Rock 5 Model B 8GB SBC features a 2.5GbE port, which delivers higher bandwidth headroom than standard gigabit connections. Match port speed to your local switch capabilities to ensure full throughput.

3. Evaluate Storage Drive Interfaces

   Storage requirements determine whether onboard memory suffices or external interfaces are needed. Onboard eMMC and M.2 PCIe slots provide fast system storage for standard single-board configurations. When building network attached storage appliances, you need multi-drive interfaces. Check for multi-drive expansion modules if you plan to aggregate mechanical or solid-state drives. The Radxa Penta 5-Port SATA HAT provides five SATA drive connections supporting total capacities up to 100T. Note that multi-drive modules demand extra power, requiring an external ATX or 12V DC power supply to run properly.

4. Plan Power Delivery Options

   Power delivery affects cable routing and deployment placement. Remote hardware setups often benefit from Power over Ethernet, which combines electrical supply and data across one networking line. Review your board for PoE header pins before picking power components. The Radxa 25W PoE+ Module supplies up to 25W of solder-free power over Ethernet for compatible boards. This configuration removes the need for separate AC wall adapters near remote hardware. Verify that your network switch or injector supports the 25W PoE+ standard to deliver sufficient wattage.

5. Verify Enclosure Port Clearances

   Physical enclosures protect delicate components from debris and handling damage, but port alignments vary between board revisions. Metal enclosures must match connector cutouts precisely to maintain access to power, display outputs, and expansion headers. For example, the Radxa Rock 5T Metal Case protects matching hardware, but it omits an HDMI input cutout. Check your planned peripheral setup to ensure the housing does not block essential video inputs or header pins. Confirm board dimensions and port layouts before pairing any enclosure with your board.
