BIGTREETECH Pi 2 SBC and CB2 module for 3D printers now feature Rockchip RK3566 SoC with Gigabit Ethernet

BIGTREETECH Pi 2 and the BIGTREETECH CB2 Compute Modules

BIGTREETECH recently announced the release of the BIGTREETECH Pi 2 SBC and BIGTREETECH CB2 SoM, both powered by the Rockchip RK3566 SoC. These new modules are direct upgrades from the BIGTREETECH Pi v1.2 and BIGTREETECH CB1, which we covered and reviewed in our previous posts. Specially designed for 3D printers, these new modules have a similar form factor to that of a Raspberry Pi and the RPI CM4 module, and come with a set of upgraded features including support for GbE Ethernet, dual-band WiFi, up to 32GB of LPDDR4 RAM, eMMC storage, HDMI, USB, and more. BIGTREETECH Pi 2 Specifications SoC – Rockchip RK3566 CPU – Quad-core Arm Cortex-A55 processor @ 1.8 GHz GPU – Arm Mali G52-2EE GPU with support for OpenGL ES 1.1/2.0/3.2, Vulkan 1.1, OpenCL 2.0 NPU – 0.8 TOPS AI accelerator VPU – 4Kp60 H.265/H.264/VP9 video decoding, 1080p100f H.265/H.264 video encoding System Memory – 2GB LPDDR4 (Customizable – 1GB/2GB/4GB/8GB) […]

Rockchip RK3588’s NPU open-source driver performs object detection at 30 FPS

Rockchip RK3588 open source NPU driver

Tomeu Vizoso has been working on an open-source driver for NPU (Neural Processing Unit) found in Rockchip RK3588 SoC in the last couple of months, and the project has nicely progressed with object detection working fine at 30 fps using the SSDLite MobileDet model and just one of the three cores from the AI accelerator. Many recent processors include AI accelerators that work with closed-source drivers, but we had already seen reverse-engineering works on the Allwinner V831’s NPU a few years ago, and earlier this year, we noted that Tomeu Vizoso released the Etvaniv open-source driver that works on Amlogic A311D’s Vivante NPU. Tomeu has now also started working on porting his Teflon TensorFlow Lite driver to the Rockchip RK3588 NPU which is closely based on NVIDIA’s NVDLA open-source IP. He started his work in March leveraging the reverse-engineering work already done by Pierre-Hugues Husson and Jasbir Matharu and was […]

Orange Pi 5 Pro – A low-cost Rockchip RK3588S SBC with up to 16GB LPDDR5 RAM, dual HDMI video output

Orange Pi 5 Pro

As mentioned in the Orange Pi Developer Conference 2024 article, the Orange Pi 5 Pro launch was just around the corner, and the latest Rockchip RK3588S SBC is now available on Amazon or Aliexpressfor $109 and up with 16GB LPDDR5 RAM, but cheaper 4GB ($60) and 8GB ($80) variants are coming soon. One would think the Orange Pi 5 Pro would be an evolution of the Orange Pi 5 SBC with LPDDR4 memory, and in some ways it is, but there are enough changes to display ports, storage, wireless, GPIO header, and even the form factor that make a direct comparison challenging. Orange Pi 5 Pro specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz GPU – Arm Mali-G610 MP4 GPU with OpenGL ES 3.2,  OpenCL 2.2, and Vulkan 1.2 support VPU – […]

Axelera Metis PCIe Arm AI evaluation kit combines Firefly ITX-3588J mini-ITX motherboard with 214 TOPS Metis AIPU PCIe card

Metis PCIe Arm Evaluation Kit

Axelera has announced the general availability of several Metis PCIe AI Evaluation Kits that combine the company’s 214 TOPS Metis AIPU PCIe card with x86 platforms such as Dell 3460XE workstation and Lenovo ThinkStation P360 Ultra computers, Advantech MIC-770v3 or ARC-3534 industrial PCs, or the Firefly ITX-3588J mini-ITX motherboard powered by a Rockchip RK3588 octa-core Cortex-A76/A55 SoC. We’ll look into detail about the latter in this post. When Axelera introduced the Metis Axelera M.2 AI accelerator module in January 2023 I was both impressed and doubtful of the performance claims of the company since packing a 214 TOPS Metis AIPU in a power-limited M.2 module seemed like a challenge. But it was hard to check independently since the devkits were not available yet although the company only started their early-access program in August last year. Now, anybody with an 899 Euros and up budget can try out their larger Metis […]

Testing Cytron MAKERDISK M.2 NVMe SSDs on Raspberry Pi 5 with GEEKWORM X1001 and Waveshare M.2 PCIe HAT+

MAKERDISK M.2 NVMe SSD Raspberry Pi 5 review

Cytron has sent us a few of their MAKERDISK NVMe SSDs preloaded with Raspberry Pi OS so that we can test them on a Raspberry Pi 5 SBC, either with a GEEKWORM X1001 or Waveshare M.2 PCIe HAT+ add-on boards both of which were also provided by the company. Ever since the first M.2 PCIe HATs for the Raspberry Pi 5 were released, we knew Raspberry Pi Limited was working on its own model, and based on some Twitter/X “rumors” (with photos) the launch of the official M.2 HAT+ should be just around the corner. So it’s the perfect timing to test some SSDs on the Raspberry Pi 5 even though I’ve yet to get the official HAT+ Cytron “MAKERDISK” package unboxing The Malaysian company sent me a kit with everything I needed to get started, minus the Raspberry Pi 5 I already owned. This includes 128GB or 256GB NVMe […]

Orange Pi Developer Conference 2024, upcoming Orange Pi SBCs and products

Orange Pi Developer Conference 2024

Orange Pi held a Developer Conference on March 24, 2024, in Shenzhen, China, and while I could not make it, the company provided photos of the event where people discussed upcoming boards and products, as well as software support for the Orange Pi SBCs. So I’ll go through some of the photos to check out what was discussed and what’s coming. While Orange Pi is mostly known for its development boards the company has also been working on consumer products including the Orange Health Watch D Pro and the OrangePi Neo handheld console. The Orange Pi Watch D Pro is said to implement non-invasive blood glucose monitoring, blood pressure monitoring, one-click “micro-physical examination” and other functions to to help users monitor their health monitoring. The Watch D Pro uses a technique that emits a green light to measure glucose levels in the blood, and we’re told it’s accurate enough to […]

Rockchip RK3582 is a cost-down version of RK3588S with two Cortex-A76 cores, four Cortex-A55 cores, no GPU

Rockchip RK3582

Rockchip RK3582 hexa-core SoC is pin-to-pin compatible with the popular Rockchip RK3588S octa-core Cortex-A76/A55 SoC, but only features two Cortex-A76 cores, a 5 TOPS NPU (instead of 6 TOPS) and does not come with a 3D GPU. I was first made aware of the Rockchip RK3582 in October 2023 when I was sent a photo of a board allegedly for a TV box, but while the RK3582 still features a 4K video decoder, the lack of a 3D GPU could make it problematic with 3D accelerated user interface. We now have more details with Radxa having released the datasheet and a few more interesting details. Rockchip RK3582 specifications: Hexa-core CPU – 2x Cortex-A76 and 4x Cortex-A55 cores in dynamIQ configuration (frequencies are still shown as TBD in the datasheet) GPU No 3D GPU 2D graphics engine up to 8192×8192 source, 4096×4096 destination AI Accelerator – 5 TOPS NPU 3.0 (Neural […]

Review of Purple Pi OH – A Rockchip RK3566 SBC tested in 2GB/16GB and 4GB/32GB configurations

Review of Purple Pi OH and Purple Pi OH Pro

Hello, I am going to review the Purple Pi OH boards from Wireless-Tag. The Purple Pi OH is a single-board computer (SBC) mechanically compatible with the Raspberry Pi. They are designed for personal mobile Internet devices and AIoT devices, which can be used in various applications, such as tablets, speakers with screens, and lightweight AI applications. The manufacturer sent me two models. The first model is the Purple Pi OH, which is equipped with 2GB of memory and 16GB of storage space and supports 2.4GHz Wi-Fi. The second model is the Purple Pi OH Pro, equipped with 4GB of memory and 32GB of storage space. This board supports both 2.4GHz and 5GHz Wi-Fi. The other components of both devices are almost the same. They are powered by the Rockchip RK3566 chip, which integrates a quad-core Cortex-A55 processor up to 1.8 GHz, a Mali-G52 GPU from Arm for 3D graphics acceleration, […]
