ALLNET Radxa Taco High Performance NAS a router board pre Raspberry Pi CM5 a Radxa CM4

Homelab enthusiasts and small office administrators seeking a compact yet powerful network storage and routing solution will find the ALLNET Radxa Taco board delivers enterprise-grade connectivity in a single, versatile platform. Built around the Raspberry Pi Compute Module 4 or Radxa CM4, this board transforms a simple module into a full-featured NAS and router with five SATA ports, dual 2.5GbE networking, and NVMe storage support.

Key specifications

• Compatible with Raspberry Pi Compute Module 4 (CM4) and Radxa CM4
• 5x SATA 3.0 (6Gbps) ports via JMB585 controller
• 1x M.2 M-Key slot for 2280 NVMe SSD (PCIe Gen 2 x1)
• 2x 2.5 Gigabit Ethernet ports (RTL8125B controllers)
• 2x USB 3.0 Type-A, 1x USB 2.0 Type-A, 1x USB 2.0 header
• 1x HDMI 2.0 output supporting up to 4K@60Hz
• 1x Mini-PCIe slot for WiFi/LTE expansion
• MicroSD card slot for CM4 Lite/eMMC-less versions
• 40-pin Raspberry Pi compatible GPIO header
• 4-pin PWM fan header and RTC with CR1220 battery holder
• DC 12V power input (5.5/2.1mm barrel jack)
• Supports Debian/Ubuntu, Android, OpenWRT, and more

Why choose it

The Radxa Taco stands out with its exceptional storage density and networking speed. Five SATA ports allow you to build a RAID array for data redundancy, while the M.2 slot provides fast caching or boot storage. Dual 2.5GbE ports enable link aggregation or separate LAN/WAN routing, making it ideal for high-throughput applications. The 40-pin GPIO header ensures compatibility with a vast ecosystem of Raspberry Pi HATs and sensors, and the RTC keeps accurate time even when powered off.

Ideal use cases

• Building a high-capacity NAS with RAID protection for home or small office
• Creating a custom router/firewall with dual 2.5GbE ports and OpenWRT
• Hosting media servers, home automation, or network-attached storage
• Developing IoT or edge computing projects requiring SATA and NVMe storage

Good to know

The board requires a compatible compute module (Raspberry Pi CM4 or Radxa CM4) and a 12V DC power supply, which are not included. The M.2 slot supports PCIe Gen 2 x1 speeds, suitable for NVMe SSDs up to 2280 size. For wireless connectivity, a Mini-PCIe WiFi card can be added. The RTC battery (CR1220) is user-replaceable.
