My nephew just finished building his first home lab, and wanted an RK3588 single-board computer to run as a lightweight edge server. When he asked me which one to buy, I realized the RK3588 ecosystem has exploded – there are now so many options it’s genuinely hard to pick the right one.
Just a few years ago, if you wanted decent ARM performance in an SBC form factor, you basically had one real choice. Now Rockchip’s RK3588 has become the de facto standard for high-performance single-board computers . The octa-core chip (4×Cortex-A76 @ 2.4GHz + 4×Cortex-A55 @ 1.8GHz) packs a 6 TOPS NPU, an ARM Mali-G610 GPU, and handles 8K video . It’s essentially desktop-class performance in a form factor that fits in your pocket.
The problem is, for someone just getting started (or even for seasoned developers), the sheer number of RK3588 boards in 2026 makes choosing one feel like a chore. Everyone’s building one now. After testing a bunch, here’s my honest take on the top five.
1. Kiwi Pi 5B
This is the board I keep going back to. The Kiwi Pi 5B offers the balance of features, connectivity, and value in the RK3588 ecosystem. It’s not the cheapest, but it’s the one I’d recommend to most people.
The standout feature is the dual 2.5G Ethernet ports. If you’re building a home router, NAS, or any kind of network appliance, this is a game-changer – you can do link aggregation or set up a failover configuration without dongles or USB adapters. It also has an M.2 slot for 4G/5G modules, which is rare at this price point.
The board supports up to 32GB of LPDDR4X memory and includes 128GB of onboard eMMC storage (expandable via PCIe 3.0 x4 M.2 2280 NVMe) . The software support is solid – Ubuntu 22.04, Debian 11, and Android 15 are all officially supported with well-maintained kernel builds .
Who it’s for: Network engineers, homelab enthusiasts, and anyone building a router, NAS, or edge server that needs serious connectivity.
2. Orange Pi 5 Plus
Orange Pi’s 5 Plus is the runner-up, and in some ways it’s actually the better choice for specific use cases. It’s been widely adopted in the community, which means excellent documentation and third-party support.
The Plus has a single 2.5G Ethernet port rather than two, but it makes up for it with active cooling – the included fan helps sustain performance under heavy loads . The RK3588 runs warm, and passive cooling sometimes isn’t enough. With the fan, you’re less likely to hit thermal throttling during long workloads like video transcoding or AI inference.
It also features a more comprehensive video output suite: 2×HDMI 2.1 outputs (8K@60FPS), Type-C with DP 1.4A (8K@30FPS), and MIPI-DSI . If you’re building a media center or digital signage system, this matters.
Who it’s for: Media center builders, developers doing sustained compute work, and anyone who prefers a larger community for troubleshooting.
3. Radxa Rock 5B
Radxa’s Rock 5B is the premium option. It’s the board you buy when you want everything – maximum RAM, fastest storage, and the most flexible expansion .
The Rock 5B supports up to 32GB of RAM and uses LPDDR5 (instead of LPDDR4X), which offers better bandwidth and lower power consumption . That’s a meaningful difference if you’re running memory-intensive AI models or large container workloads. It also has a full PCIe 3.0 x4 slot for NVMe SSDs, plus an M.2 E-key slot for Wi-Fi/BT modules .
The documentation from Radxa is excellent – they provide schematics, detailed technical manuals, and actively contribute to the mainline Linux kernel. If you’re doing custom embedded development or need long-term support, this is the board to get.
Who it’s for: Developers building commercial products, engineers doing custom embedded work, and anyone who needs the possible memory bandwidth.
4. Kiwi Pi 5 Pro
If you need even more I/O and expansion than the 5B, the Kiwi Pi 5 Pro steps up. It’s basically the 5B’s bigger sibling with additional connectivity options.
The Pro offers the same dual 2.5G Ethernet and cellular expansion, but adds three MIPI-CSI camera interfaces – ideal for machine vision or multi-camera surveillance applications. It also includes more GPIO headers (60-pin, 50-pin, and 39-pin) for industrial control and automation projects .
The board is slightly more expensive, but the extra I/O can save you from buying additional interface boards or USB adapters.
Who it’s for: Industrial automation engineers, robotics developers, and anyone building multi-camera vision systems.
5. Orange Pi 5 Max / Ultra
Rounding out the list are Orange Pi’s two newer variants – the 5 Max and 5 Ultra. They share the same RK3588 core but target slightly different use cases .
The 5 Max focuses on wireless connectivity and camera support. It has onboard Wi-Fi 6E and Bluetooth 5.3, plus three camera interfaces for stereo vision or multi-channel video capture . The 5 Ultra adds HDMI input (4K@60FPS), making it perfect for video capture and streaming applications .
Both boards use LPDDR5 memory and have a more compact form factor than the 5 Plus. They’re ideal for portable projects or deployment in tight spaces.
Who it’s for: Robotics developers (5 Max), streamers and video capture enthusiasts (5 Ultra), and anyone who needs built-in wireless.
The Verdict
| Board | For | Key Feature |
| Kiwi Pi 5B | General purpose | Dual 2.5G Ethernet |
| Orange Pi 5 Plus | Media servers | Active cooling, quad-display support |
| Radxa Rock 5B | Commercial dev | LPDDR5 |
| Kiwi Pi 5 Pro | Industrial/IoT | Triple camera, most I/O |
| Orange Pi 5 Max/Ultra | Wireless/Video | Built-in Wi-Fi 6E, HDMI input |
At the end of the day, it’s hard to justify buying anything else when the RK3588 exists – but picking the right RK3588 board requires knowing what you’re actually building.
