Radxa E25 carrier board, 2.5GbE switch, and WiFi 6 router

Radxa E25 2.5GbE switch-Xiaomi AX6000 WiFi 6 router

I’ve just received an early sample of Radxa E25 dual 2.5 GbE carrier board for Radxa CM3 Plus (RK3568) system-on-module, a 2.5GbE TP-Link switch, and Xiaomi AX6000 WiFi 6 + 2.5GbE router. Here’s the back story before looking into the devices. I’ll soon have to review UP Xtreme i11 mini PC with a 2.5GbE port, and after writing about the upcoming ROCK5 Model B SBC with both 2.5GbE and WiFI 6/6E, I realized I should really get some hardware to test 2.5GHz and WiFi 6. So I started to ask what could be the best options for a $200 budget. While thinking about it, I remember Radxa was working on the Radxa E23 board with 2.5GbE, and adding a WiFi 6 USB dongle might be an option. But they told me Radxa E25 would be a better option with two 2.5GbE ports and support for WiFi 6, although that one […]

Linux 5.16 Release – Main Changes, Arm, RISC-V and MIPS architectures

Linux 5.16 release

Linus Torvalds has just announced the release of Linux 5.16: Not a lot here since -rc8, which is not unexpected. We had that extra week due to the holidays, and it’s not like we had lots of last-minute things that needed to be sorted out. So this mainly contains some driver fixes (mainly networking and rdma), a cgroup credential use fix, a few core networking fixes, a couple of last-minute reverts, and some other random noise. The appended shortlog is so small that you might as well scroll through it. This obviously means that the merge window for 5.17 opens tomorrow, and I’m happy to say I already have several pending early pull requests. I wish I had even more, because this merge window is going to be somewhat painful due to unfortunate travel for family reasons. So I’ll be doing most of it on the road on a laptop […]

Year 2021 in review – Top 10 posts and statistics

cnx software happy new year 2022

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and  Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]

Rockchip RK3588 datasheet available, SBC’s coming soon

RK3588 Block Diagram

We had most Rockchip RK3588 specifications so far for the long-awaited Cortex-A76/Cortex-A55 processor, but at today’s Rockchip Developer Conference 2021, more information surfaces with impressive CPU and GPU benchmarks, and the Rockchip RK3588 datasheet has just dropped from the sky directly into my laptop, as such document usually does. At least two single board computers are expected to soon follow from Radxa and Pine64. Rockchip RK3588 datasheet Since we have the datasheet, we can confirm some of the specifications of RK3588, and get additional details: CPU – 4x Cortex-A76 @ up to 2.4/2.6 GHz and 4x Cortex-A55 cores @ 1.8 GHz in dynamIQ configuration GPU Arm Mali-G610 MP4 “Odin” GPU with support for OpenGLES 1.1, 2.0, and 3.2, OpenCL up to 2.2 and Vulkan1.2 2D graphics engine up to 8192×8192 source, 4096×4096 destination AI Accelerator – 6 TOPS NPU 3.0 (Neural Processing Unit) VPU Video decoding 8Kp60 H.265, VP9, AVS2, […]

VisionFive V1 RISC-V Linux SBC resurrects BeagleV StarFive single board computer

VisionFive V1 RISC-V SBC

Last summer we reported that BeagleV StarFive RISC-V SBC would not be manufactured, but all was not lost as StarFive would collaborate with Radxa to make a new single board computer based on their JH7100 dual-core 64-bit RISC-V processor. But thanks to a report on Heise and extra photos acquired by CNX Software, we now have more details about the board that mostly comes with the same features as the BeagleV StarFive, but a completely different layout that brings all the main ports to one side of the board. VisionFive V1 specifications: SoC – StarFive JH7100 Vision SoC with: Dual-core Sifive U74 RISC-V processor @ 1.5 GHz with 2MB L2 cache Vision DSP Tensilica-VP6 for computing vision NVDLA Engine 1 core (configuration 2048 MACs @ 800MHz  – 3.5 TOPS) Neural Network Engine (1024MACs @ 500MHz – 1 TOPS) VPU – H.264/H.265 decoder up to 4Kp60, dual-stream decoding up to 4Kp30 […]

Seaberry Mini-ITX carrier board for Raspberry Pi CM4 exposes 11 PCIe slots and sockets

SeaBerry mini-ITX motherboard Raspberry Pi CM4

The Raspberry Pi CM4 may only have a one PCIe x1 Gen 2 interface, but this has not stopped ALFTEL from designing Seaberry, a mini-ITX carrier board for the Raspberry Pi Compute Module 4 with eleven slots and sockets making use of the single 5 Gbps PCIe Gen 2 interface. The board also offers two SATA ports, one Gigabit Ethernet port, one RJ45 console port, two HDMI ports, a micro SD card slot, two USB 2.0 ports, as well as the usual 40-pin GPIO expansion header, besides the PCIe x16 slot, a PCIe x1 side slot, and M.2 and mPCIe sockets. Seaberry carrier board specifications: Compatible systems-on-module Raspberry Pi CM4 module (Regular or Lite) Radxa CM3 Pine64 SoQuartz Storage – 1x MicroSD card for Raspberry Pi CM4 Lite, 1x M.2 socket for NVMe SSD (See PCIe expansion section) Video Output – 2x HDMI output ports, 1x MIPI DSI connector Camera […]

Radxa CM3 – A drop-in Raspberry Pi CM4 alternative

Radxa E23 minimal Radxa CM3 carrier board

Radxa CM3 is a system-on-module that offers an alternative to the Raspberry Pi CM4, with the same form factor allowing it to become a drop-in replacement, but switching from a Broadcom BCM2711 processor to a Rockchip RK3566 quad-core Cortex-A55 SoC. Radxa CM3 will work with existing carrier boards for the Raspberry Pi Compute Module 4, albeit some features such as dual HDMI are not available, instead, providing a single HDMI, but the module also offers extra features through an additional 100-pin board-to-board with interfaces such as SATA III and USB 3.0. Let’s compare Radxa CM3 specifications to the ones of Raspberry Pi CM4. Comparing Broadcom BCM2711 quad-core processor and Rockchip RK3566, as the Cortex-A72 may still be faster on some workloads despite the lower frequency, and some other workloads may be dramatically faster on RK3566, for example for those using Armv8 Crypto extensions missing on all Raspberry Pi, which we […]

Raspberry Pi Zero 2 W vs Radxa Zero – Features and benchmarks comparison

Raspberry Pi Zero 2 W vs Radxa Zero

The just-announced Raspberry Pi Zero 2 W is not the first quad-core Arm SBC following Raspberry Pi Zero form factor, and back in 2017, the Banana Pi BPI-M2 Zero was introduced for $15, and the Radxa Zero was unveiled last June with an Amlogic S905Y2 SoC with price starting at $15 as well. With its Allwinner H2+ quad-core Cortex-A7 processor clocked at 1 GHz and a price bumped up to $23, the Banana Pi M2 Zero has mostly become irrelevant, but the Radxa Zero may still be considered by some people with a 1.8 GHz processor, and options for up to 4GB RAM, so let’s see how features compare against Raspberry Pi Zero 2 W, followed by some benchmark numbers. Raspberry Pi Zero 2 W vs Raxda Zero – Features If we just look at the comparison table, the Radxa Zero is equivalent or superior in almost every way, except […]
