NanoPi R28S – A tiny dual GbE Rockchip RK3528A wireless SBC and router with a USB-C console port

NanoPi R28S Dual GbE router USB C Debug port

NanoPi R28S is yet another tiny dual Gigabit Ethernet single board computer or router (with a metal enclosure), and the second from FriendlyELEC to implement a USB-C console port, often requested by our readers, after the NanoPi R2S Plus launched in 2024. At just 49.5 x 49.5 x 24 mm in its metal case, the Rockchip RK3528A-powered router also features 1GB LPDDR4, a microSD card slot and an eMMC module socket for storage, WiFi 6 and Bluetooth 5.3 wireless connectivity. The USB-C ports are only used for power, eMMC firmware upgrades, and debugging, and the system doesn’t feature any USB port for data connectivity, nor any GPIO header for expansion. In other words, it’s mostly useful for networking (firewalls, soft routers), as well as IoT gateway applications. NanoPi R28S specifications: SoC – Rockchip RK3528A CPU – Quad-core ARM Cortex-A53 @ 1.8 GHz GPU – Arm Mali-450 GPU with support for […]

Jetway SMC-ARK1 – A Rockchip RK3588 SMARC 2.1 compliant system-on-module

Rockchip RK3588 SMARC 2.1 system-on-module

Jetway has introduced the SMC-ARK1, a new SMARC system-on-module built around the Rockchip RK3588 octa-core processor. Designed for embedded computing and edge AI applications, the board includes up to 16GB of LPDDR4x memory and up to 128GB of eMMC flash, dual GbE, and an Ampak AP6398SV Wi-Fi 5 and Bluetooth 5.0 module, alongside a dedicated HDMI input via an I-PEX FPC connector. We’ve previously written about the Geniatech SOM-3568-SMARC module based on the Rockchip RK3568, but Jetway’s SMC-ARK1 appears to be the first SMARC module we’ve seen based on the Rockchip RK3588. The module follows the SMARC 2.1 short form-factor specification (82 × 50 mm) and can be used with compatible SMARC carrier boards. Jetway SMC-ARK1 specifications: SoC – Rockchip RK3588 octa-core processor with CPU – 4x Cortex‑A76 cores @ up to 2.4 GHz, 4x Cortex‑A55 cores @ 1.8 GHz GPU – Arm Mali-G610 MP4 GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 […]

Orange Pi 5B SBC gets Ubuntu Desktop and Audio Production OS images with Bluetooth/Wi-Fi fix missed for 8 years

Joshua Riek’s ubuntu-rockchip project helped many run working OS images for their Rockchip SBCs, but due to burnout and lack of support, he decided to step away in late 2024, and the project is now archived. However, that doesn’t mean his efforts have gone to waste. GitHub user defcom5-rockchip forked the project and released two Ubuntu 24.04-based distributions working on the Orange Pi 5B, notably integrating two fixes for the Ampak AP6275P WiFi and Bluetooth module, including one that Cypress apparently already fixed in 2018, but took a while to be integrated into Rockchip OS images. Short description of the two OS images Pi Desktop v1.0-beta – A curated daily-driver desktop: 4K@120 via custom VOP2/dclk kernel work, hardware video decode, zero snaps/telemetry, and “self-healing Bluetooth”: a background service that revives the AP6275P radio wedge in ~10 seconds automatically. Pi Studio v1.3 — the audio-production sibling: low-latency kernel (PREEMPT/1000Hz), Sonic Pi […]

Geniatech XPI-3576-CM5 – A Raspberry Pi CM5-compatible Rockchip RK3576 AI Compute Module with WiFi 6, Bluetooth 5.3

Geniatech XPI-3576-CM5 is a Rockchip RK3576 octa-core Arm Cortex-A72/A53 system-on-module based on the Raspberry Pi CM4/CM5 form factor with up to 16GB LPDDR5 and 128GB eMMC flash. The module also features a RealTek RTL8211F Gigabit Ethernet controller, an Ampak AP6275S wireless module for dual-band WiFi 6 and Bluetooth 5.3 connectivity, and a Rockchip RK806S-5 PMIC for power management. It features two 100-pin B2B connectors, allowing it to be plugged into carrier boards designed for the Raspberry Pi CM4/CM5, with some limitations as we’ll see further below. Geniatech XPI-3576-CM5 specifications SoC – Rockchip RK3576 Octa-core CPU – 4x Cortex-A72 cores at 2.2GHz, 4x Cortex-A53 cores at 1.8GHz GPU – Arm Mali-G52 MC3 GPU at 1 GHz with support for OpenGL ES 3.2, OpenCL 2.0, and Vulkan 1.1 NPU – 6 TOPS (INT8) AI accelerator with support for INT4/INT8/INT16/BF16/TF32 mixed operations.

Reverse-engineering brings RK3576 NPU support to open-source Rocket driver for mainline Linux

Back in 2024, we noted that the open-source driver for RK3588’s NPU by Tomeu Vizoso delivered decent performance for object detection. Since then, good progress has been made, and it’s now known as the Rocket driver in mainline Linux. However, the Rockchip RK3576 SoC is not supported by the Rocket driver in mainline yet, despite sharing a similar NPU. The good news is that Ga Hing Woo has been working on mainline Linux support for the Rockchip RK3576 NPU using the Rocket driver stack and has tested the updates on the Radxa ROCK 4D running Linux 7.1-rc5. This required some serious reverse-engineering work due to hidden registers not documented in the TRM. Ga Hing Woo (also written as Jiaxing Hu) sent us an email explaining some of the challenges: Single int8 convolution now comes out byte-exact against a CPU reference on the open stack. Getting there meant reverse-engineering the compute […]
