Orange Pi 4A low-cost octa-core SBC is powered by Allwinner T527 Cortex-A55 AI SoC with a 2TOPS NPU

Orange Pi 4A

Orange Pi 4A is a new low-cost credit card-size single board computer (SBC) powered by an Allwinner T527 octa-core Cortex-A55 processor with a 2TOP NPU and offered with either 2GB or 4GB RAM. The board also comes with multiple storage options: a 128 or 256Mbit SPI NOR flash for the bootloader, an eMMC socket for up to 128GB modules, an M.2 socket for NVMe SSDs, and a microSD card slot. It’s also equipped with four USB 2.0 ports, a gigabit Ethernet port, three display interfaces (HDMI, MIPI DSI, eDP),  two camera interfaces, and a 40-pin “Raspberry Pi” header. The Orange Pi 4A is somewhat equivalent to an octa-core Raspberry Pi 3/4 with some extra features. Orange Pi 4A specifications: SoC – Allwinner T527 CPU Octa-core Arm Cortex-A55 @ up to 1.8GHz (four cores) and up to 1.42 GHz (four cores) XuanTie E906 RISC-V core @ 200MHz GPU – Arm Mali-G57 […]

Linux 6.11 Release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.11 release

Linux 6.11 is out with Linus Torvalds’ announcement on the Linux kernel mailing list (LKML): I’m once again on the road and not in my normal timezone, but it’s Sunday afternoon here in Vienna, and 6.11 is out. The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small. Nothing in particular stands out – the biggest patch in here is for Hyper-V Confidential Computing documentation. Anyway, with this, the merge window will obviously open tomorrow, and I already have 40+ pull requests pending. That said, exactly _because_ I’m on the road, it will probably be a fairly slow start to the merge window, since not only am I on my laptop, there’s OSS Europe starting tomorrow and then the […]

MIKRIK V2 Robot Car is an entry-level, open-source robotics kit built for ROS and 3D computer vision

MIKRIK V2 open source robotics kit

The MIKRIK V2 Robot Car is an open-source robotics kit for studying 3D computer vision and is compatible with both ROS1 and ROS2 software suites. The two-wheel-drive robot is powered by a Raspberry Pi 4 Model B (as a ROS1 differential drive controller) and a more powerful x86 or ARM single-board computer that can support ROS2 applications like the LattePanda Delta 3, Intel NUC, or NVIDIA Jetson Nano. The robot car uses the Intel Realsense D435i camera for 3D depth vision. It is a less expensive alternative to the iRobot Create, Husarion, and TurtleBot, and compares favorably with NVIDIA’s open-source JetBot AI robot platform. The robot car’s chassis is squared-off and made from shatterproof flex plastic. The CAD files are available on GitHub for self-assembly using a laser cutter and a 3D printer. The assembly and setup process is documented on the Hackster project page. On the software end, it […]

DietPi 9.7 and Armbian 24.8 released with improved support for Rockchip, Amlogic, and Allwinner SBCs

DietPi 9.7 Orange Pi 5 Plus

Armbian and DietPi are two separate projects that provide Linux-based OS images optimized for Arm-based single board computers. The last time we had a look at both projects was in June with the release of Armbian 24.5.1 and DietPi 9.4, but there have been several updates since then including the releases of the latest DietPi 9.7 and Armbian 24.8 Yelt just a few days ago. So let’s check out the latest changes. DietPi 9.7 DietPi is a lightweight Debian-based Linux distribution for SBCs and server systems that ships as a minimal image but users can install any packages they want, including the ones required for desktop environment, to match the requirements of the applications. It’s notably used by the Linamp project – a Raspberry Pi 4-based project that brings WinAMP to real life – that we covered a few weeks ago. DietPi 9.7 was released on August 25, 2024 with […]

Rockchip RK3588-powered Orange Pi 5 Max SBC features up to 16GB LPDDR5, 2.5GbE, onboard WiFi 6E and Bluetooth 5.3

Orange Pi 5 Max SBC

Initially teased at the Orange Pi Developer Conference earlier this year, the Orange Pi 5 Max SBC powered by a Rockchip RK3588 SoC is now available on Amazon and Aliexpress for $95 and up with 8GB or 16GB LPDDR5, and support for eMMC flash modules or soldered on eMMC flash. A 4GB RAM version is also planned for $75. The Orange Pi 5 Max is basically a cost-down version of the Orange Pi 5 Plus with fewer interfaces (e.g. 1x 2.5GbE vs 2x 2.5GbE, no HDMI input, etc..), higher bandwidth LPDDR5 memory, onboard WiFi 6E and Bluetooth 5.3, and a smaller form factor between Pico-ITX and credit card size. Orange Pi 5 Max specifications: SoC – Rockchip RK3588 CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz Arm Mali-G610 MP4 GPU with support for OpenGL ES1.1/2.0/3.2, OpenCL 2.2, […]

Rockchip RKLLM toolkit released for NPU-accelerated large language models on RK3588, RK3588S, RK3576 SoCs

Rockchip RK3588 RKLLM

Rockchip RKLLM toolkit (also known as rknn-llm) is a software stack used to deploy generative AI models to Rockchip RK3588, RK3588S, or RK3576 SoC using the built-in NPU with 6 TOPS of AI performance. We previously tested LLM’s on Rockchip RK3588 SBC using the Mali G610 GPU, and expected NPU support to come soon. A post on X by Orange Pi notified us that the RKLLM software stack had been released and worked on Orange Pi 5 family of single board computers and the Orange Pi CM5 system-on-module. The Orange Pi 5 Pro‘s user manual provides instructions on page 433 of the 616-page document, but Radxa has similar instructions on their wiki explaining how to use RKLLM and deploy LLM to Rockchip RK3588(S) boards. The stable version of the RKNN-LLM was released in May 2024 and currently supports the following models: TinyLLAMA 1.1B Qwen 1.8B Qwen2 0.5B Phi-2 2.7B Phi-3 […]

High Torque Robotics Mini π is a bipedal robot powered by an Orange Pi 5 SBC

High Torque Robotics mini Pi bipedal robot

High Torque Robotics’ Mini π is a 54cm high bipedal robot that can walk and dance with two legs and leverages the Orange Pi 5 SBC’s features such as the 6 TOPS AI accelerator in the Rockchip RK3588S processor. The robot offers 12 degrees of freedom (DOF) and can run, jump, and even flip thanks to its twelve join motors that were developed by the company. The Mini π is designed for locomotion algorithm research and education and supports ZMP (zero moment point), MPC (Model Predictive Control), reinforcement learning locomotion control algorithms, and ROS SLAM navigation features.   Mini π bipedal robot highlights: SBC – Orange Pi 5 RK3588S single board computer Controller – Custom-design “high-performance underlying controller” using 4x CAN FD communication DOF – 6 DoF per leg, or 12 in total Joint motors 8x HTDM-5047-36-NE with gear ratio: 36, 16Nm peak torque 4x HTDM-4438-32-NW with gear ratio: 32, […]

Orange Pi CM5 – A Raspberry Pi CM4 alternative with up to 16GB RAM, 256GB eMMC flash

Orange Pi CM5 Raspberry Pi CM4 alternative

Orange Pi CM5 is a system-on-module mostly compatible with the Raspberry Pi CM4 (and upcoming Raspberry Pi CM5?) powered by a Rockchip RK3588S octa-core Cortex-A76/A55 processor that supports up to 16GB LPDDR4 and 256GB eMMC flash compared to the Pi CM4 module that is limited to 8GB RAM and 32GB flash. Since the Rockchip RK3588S has more interfaces than the Broadcom BCM2711 found in the Raspberry Pi CM4, the company added an extra 100-pin board-to-board connector with extra interfaces such as native USB 3.0, SATA III, CAN Bus, and an additional PCIe 2.0 x1 interface for a total of two. Orange Pi CM5 specifications: SoC – Rockchip RK3588S octa-core processor with 4x CortexA76  cores @ up to 2.4GHz, 4x CortexA55 core @ 1.8GHz Arm Mali-G610 MP4 “Odin” GPU with support for OpenGL ES1.1/2.0/3.2, OpenCL 2.2 and Vulkan 1.2 Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, […]
