Radxa E24C and E54C are mini routers and embedded boxes based on, respectively, Rockchip RK3528A and RK3582 SoCs, and equipped with four Gigabit Ethernet ports, HDMI video output, three USB ports, and an M.2 PCIe socket for NVMe SSD storage. The Radxa E24C builds upon the dual Gigabit Ethernet Raxda E20C mini network Titan, while the Radxa E54C is an “update” to the Radxa E52C mini router with four Gigabit Ethernet ports instead of two 2.5GbE ports. Radxa E24C quad GbE mini router Radxa E24C specifications: SoC – Rockchip RK3528A CPU – Quad-core Arm Cortex-A53 @ 2.0 GHz GPU – Arm Mali-G450 GPU with support for OpenGL ES1.1, ES2.0, and OpenVG 1.1 APIs VPU H.264, H.265, and AVS2 decoder up to 4Kp60 H.264 and H.265 encoder up to 1080p60 Memory – 1GB, 2GB, or 4GB LPDDR4 Storage 8GB, 16GB, or 32GB eMMC 5.1 flash MicroSD card slot (UHS-I) M.2 2280 Key-M […]
Review of GL.iNet Comet (GL-RM1) KVM-over-IP solution and ATX power control board
GL.iNet sent me a Comet (GL-RM1) remote KVM box for review, along with a GL-ATXPC ATX Power Control Board. I’ll start this review with an unboxing and a teardown, then I’ll use the GL.iNet Comet with a Raspberry Pi 4 SBC to control it from a web browser in the LAN and the GLKVM app from the Internet. Finally, I’ll connect the GL-ATXPC and GL-RM1 to an Orion O6 mini-ITX motherboard to test ATX power control. GL.iNet Comet (GL-RM1) unboxing I received a parcel with two retail boxes: one for the GL-ATXPC ATX power control board and the other for the GL-RM1 Comet Remote KVM. The GL-RM1 ships with an HDMI cable, an Ethernet cable, a USB-A to USB-C cable for keyboard/mouse emulation, and a USB-C to USB-C cable for power, as well as a card with a QR code to connect with GL.iNet, and a getting started guide in […]
Allwinner A527, T527, and A733 datasheets, user manuals, and Linux SDK released
The datasheets, user manuals, and Linux SDK for the Allwinner A527, T527, and A733 SoCs, found in some SBCs like the Avaota A1, Radxa Cubie A5E, Orange Pi 4A, and upcoming Cubie A7A, are now available on Gitlab without any NDA requirements. Allwinner SoCs used to be some of the most popular processors for SBCs in the years 2012 to 2015 due to their feature set, low cost, and support by the sunxi-linux community. Since then, interest has plummeted due to a lack of interest in open-source software by Allwinner management and the constant release of new low-cost “Cortex-A7” SoC, and Rockchip RK3566 or RK3588 are now preferred on non-Raspberry Pi SBCs. But we first heard Allwinner say they planned to work on mainline Linux support for the Allwinner A527/T527 at the Orange Pi Developer Conference in March 2024. This was further confirmed by Radxa with the Cubie A5E launch […]
Radxa Cubie A7A is a powerful SBC based on Allwinner A733 Cortex-A76/A55 AI SoC with up to 16GB RAM
Radxa Cubie A7A is an upcoming single board computer (SBC) powered by an Allwinner A733 octa-core Cortex-A76/A55 SoC with a 3 TOPS AI accelerator and up to 16GB LPDDR5 memory. Radxa came back to the Allwinner SoC family after the silicon vendor committed to improving open-source support, starting with the Radxa Cubie A5E SBC powered by an Allwinner A527/T527 SoC. But this was only the start, and we were promised a more powerful Allwinner A733 SBC before moving to the Allwinner A838 down the road. The Allwinner A733 board has now been unveiled. Meet the Radxa Cubie A7A. Radxa Cubie A7A specifications: SoC – Allwinner A733 CPU Dual-core Arm Cortex-A76 @ up to 2.00 GHz Hexa-core Arm Cortex-A55 @ up to 1.79 GHz Single-core RISC-V E902 real-time core GPU – Imagination Technologies BXM-4-64 MC1 GPU VPU 8Kp24 H.265/VP9/AVS2 decoding 4Kp30 H.265/H.264 encoding AI accelerator – Optional, up to 3 TOPS […]
Radxa ROCK 4D SBC – A Raspberry Pi lookalike powered by Rockchip RK3576 SoC with 6 TOPS AI accelerator
Radxa ROCK 4D is yet another Rockchip RK3576 SBC, but offered in a credit card form factor similar to the Raspberry Pi 3 model with the usual 40-pin GPIO header, Gigabit Ethernet ports, and four USB ports. We first noticed it when we covered the Radxa Dual 2.5G Router HAT, and I’ve just seen it added to the Linux 6.15 release, so I thought it might be a good time to cover it, especially since it’s already for sale on Allnet and AliExpress starting at $31 plus shipping. Radxa ROCK 4D specifications: SoC – Rockchip RK3576 or RK3576J (industrial-grade version) CPU – Octa-core CPU with 4x Cortex-A72 cores at 2.2 GHz, 4x Cortex-A53 cores at 2.0 GHz GPU – Arm Mali-G52 MC3 GPU with support for OpenGL ES 1.1, 2.0, and 3.2, OpenCL 2.0, and Vulkan 1.2 NPU – 6 TOPS (INT8) AI accelerator with support for INT4, INT8, INT16, […]
Linux 6.15 Release – Main changes, Arm, RISC-V and MIPS architectures
Linus Torvalds has just announced the release of Linux 6.15: So this was delayed by a couple of hours because of a last-minute bug report resulting in one new feature being disabled at the eleventh hour, but 6.15 is out there now. Apart from that final scramble, things looked pretty normal last week. Various random small fixes all over, with drivers as usual accounting for most of it. But we’ve got some bcachefs fixes, some core networking, and some mm fixes in there too. Nothing looks particularly scary. And this obviously means that the merge window opens tomorrow as usual, and I see the usual people being proactive and having sent me their pull requests. It’s memorial day tomorrow here in the US, but like the USPS, “neither snow nor rain nor heat nor gloom of night” – nor memorial day – stops the merge window. [ Actually, thinking back […]
Radxa NIO 5A credit card-sized Mediatek Genio 520 SBC showcased at Computex 2025
Radxa NIO 5A is an upcoming Mediatek Genio 520 SBC in credit card/Raspberry Pi form factor that should offer a more affordable entry into the MediaTek Genio family than Radxa Nio 12L equipped with a powerful Mediatek Genio 1200 SoC. There’s no public information on the web about it, but I was sent some photos of the board from Mediatek’s booth at Computex 2025, and we know it’s powered by the Genio 520 octa-core Cortex-A78/A55 SoC with a 10 TOPS AI accelerator and comes with “large memory and high-capacity storage”. Let’s see if we can derive more detailed specs from the photos and other public information about the SoC. Radxa NIO 5A specifications (preliminary): SoC – Mediatek Genio 520 (MT8371) CPU – Octa-core processor with 2x Arm Cortex-A78 up to 2.2 GHz (Commercial) or 2.0 GHz (Industrial) 6x Arm Cortex-A55 up to 2.0 GHz (Commercial) or 1.8 GHz (Industrial) GPU […]
Cerebro clusterboard supports up to four NVIDIA Jetson, Raspberry Pi CM4/CM5, or Radxa CM5 modules (Crowdfunding)
Cerebro is a modular board / clusterboard designed to take up to four system-on-modules such as NVIDIA Jetson SO-DIMM modules, Raspberry Pi CM4 or CM5, or Radxa CM5. The board integrated a BMC for intercommunication between the CPU modules. The Cerebro was designed out of frustration as the team at Sparklab Solution could not find a solution where boards would work together seamlessly. While there are other clusterboards for Raspberry Pi Compute modules, the Cerebro motherboard provides more flexibility with three M.2 sockets per node, a built-in BMC and optional expandable BMC, KVM support between each node, dual Ethernet, a 10 Gbps USB 3.2 port, and more. Specifications: Compute Modules 4x SODIMM-260 slots Compatibility Nvidia Jetson Orin NX/Nano Raspberry Pi CM4/CM5 via adapter Radxa CM5 via adapter Supports mix and match of different models Storage 2x M.2 key-M slots per node (8x in total) for NVMe SSD 1x MicroSD card […]
