Radxa Teases the MediaTek Genio 520-Powered Raspberry Pi-Like NIO 5A Single-Board AI Computer
Compact SBC includes a 10-TOPS neural coprocessor for low-power high-performance machine learning at the edge.
An attendee at Computex 2025 in Taipei has lifted the lid on an as-yet unannounced Raspberry Pi-style single-board computer from Radxa, the NIO 5A — featuring MediaTek's recently-launched edge artificial intelligence-targeting Genio 520 system-on-chip at its heart.
"NIA 5A [is a] single-board computer with high-performance AI," signage at the company's Computex booth explains, above what is presumably a pre-production or first-production sample of the board. "[It has] large memory and high-capacity storage, high-speed Wi-Fi 6E & Bluetooth 5.3, powerful multimedia processing capabilities for encode & decode, [and can be used for] edge computing [in] intelligent security/smart retail/cloud computing/smart home."
The hardware at the heart of the board, brought to our attention by CNX Software, is the MediaTek Genio 520, announced by the company two months ago alongside the more powerful Genio 720. Designed as an upgrade to the earlier Genio 500, the chip includes the same two Arm Cortex-A78 cores running at up to 2.2GHz and six Cortex-A55 cores running at up to 2GHz and Arm Mali-G57 MC2 graphics processor but alongside an upgraded eighth-generation neural coprocessor delivering a claimed 10 tera-operations per second (TOPS) of compute for on-device machine learning and artificial intelligence workloads.
Elsewhere on the board is a microSD Card slot for storage, UFS 3.1 and eMMC 5.1 support, an HDMI port supporting up to 4k60 resolution, a MIPI Camera Serial Interface (CSI) input, a gigabit Ethernet port with optional Power-over-Ethernet (PoE) compatibility, an on-board Wi-Fi 6E and Bluetooth 5.3 module, two USB 3.2 Gen. 1 Type-A and two USB 2.0 Type-A ports, a Raspberry Pi-compatible 40-pin general-purpose input/output (GPIO) header, and a 16-pin flat flexible circuit (FFC) connector carrying a single PCI Express Gen. 2 lane — and, like the GPIO connector, compatible with the pinout of the Raspberry Pi 5's PCIe connector.
What Radxa isn't yet sharing is the price: while it's clear that the board is to land in its line-up below the existing NIO 12L, which features MediaTek's higher-end Genio 1200 chip, exact pricing has not been shared — and will depend on exact specifications chosen, with memory capacities up to 16GB of LPDDR5 on offer with or without UFS 3.1 or eMMC 5.1 flash modules. Attendees at Computex, meanwhile, may be able to elicit more information at the Radxa stand.
