Orange Pi CM5 “Tablet” Base Board drops Ethernet for WiFi 5, adds battery support, M.2 socket, 26-pin GPIO header…

The Orange Pi CM5 was launched as an alternative to Raspberry Pi CM4/CM5 last July with a Rockchip RK3588S octa-core Cortex-A76/A55 SoC, up to 16GB LPDDR4x, 256GB eMMC flash, and three board-to-board connectors maintaining partially compatibility with the Raspberry Pi Compute Module 4. At the time, Orange Pi also introduced the Orange Pi CM5 Base Board with HDMI 2.1, one Gigabit Ethernet port, two 2.5GbE ports, USB 3.0/2.0 ports, four camera connectors, and more. The company has now launched the Orange Pi CM5 “Tablet” Base Board without Ethernet ports, making use of WiFi 5 and Bluetooth 5.0 for networking instead. It keeps many of the same features but adds a 26-pin GPIO header, an M.2 Key-M socket for SSD storage, DP 1.4 and MIPI DSI display interfaces, and various audio interfaces. However, it does with “only” three camera interfaces. It’s quite thick to be used in a typical tablet, but […]

iKOOLCORE R2 Max review – Part 2: 10GbE on an Intel N100 mini PC with OpenWrt (QWRT), Proxmox VE, Ubuntu 24.04 and pfSense 2.7.2

iKOOLCORE R2 Max Review Proxmox VE Ubuntu 22.04

I’ve already checked out iKOOLCORE R2 Max hardware in the first part of the review with an unboxing and a teardown of the Intel N100 system with two 10GbE ports and two 2.5GbE ports. I’ve now had more time to test it with an OpenWrt fork, Proxmox VE, Ubuntu 24.04, and pfSense, so I’ll report my experience in the second and final part of the review. As a reminder, since I didn’t have any 10GbE gear so far, iKOOLCORE sent me two R2 Max devices, a fanless model and an actively-cooled model. I was told the fanless one was based on Intel N100 SoC, and the actively-cooled one was powered by an Intel Core i3-N305 CPU, but I ended up with two Intel N100 devices. The fanless model will be an OpenWrt 23.05 (QWRT) server, and the actively cooled variant be the device under test/client with Proxmox VE 8.3 server […]

How to use iperf3 in multi-thread mode for 10Gps+ Ethernet testing

With 10GbE becoming more widespread and often found in entry-level hardware, the CPU may become the bottleneck, so I’ll explain how to use iperf3 in multi-thread mode to fully saturate the 10GbE bandwidth even with a system based on a relatively low-end multi-core processor.

For this tutorial, I use two iKOOCORE R2 Max mini PCs with two 10GbE interfaces each and an Intel N100 quad-core processor running an OpenWrt fork (QWRT) and Proxmox VE (Debian) respectively. I will show how I can fully saturate the 10GbE interfaces using multithreading, but not with a typical iperf3 single-core test.

Orange Pi 5 Ultra SBC offers HDMI 2.1 output and HDMI 2.0 input

The Orange Pi 5 Ultra is a Rockchip RK3588 SBC that’s slightly larger than a business card and visually identical to the Orange Pi 5 Max introduced last August, but replacing one of the two HDMI 2.1 video outputs on the latter with an HDMI 2.0 input port. The new single board computer is still offered with up to 16GB LPDDR5, an eMMC flash module connector or soldered-on eMMC flash, an M.2 socket for an NVMe SSD, 2.5GbE and WiFi 6E networking, and four USB 3.0/2.0 ports. Orange Pi 5 Ultra 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, and Vulkan 1.2 6 TOPS AI accelerator with support for INT4/INT8/INT16/FP16 mixed operation VPU – 8Kp60 H.265/VP9/AVS2 10-bit decoder, 8Kp30 H.264 decoder, […]

$16 Banana Pi BPI-WiFi5 router is powered by Siflower SF19A28 dual-core MIPS SoC

Banana Pi BPI WiFi5 Low-cost WiFi 5 router

Banana Pi BPI-WiFi5 is a low-cost WiFi 5 AC1200 router with four gigabit Ethernet ports powered by a 1.2 GHz Siflower SF19A28 dual-core MIPS SoC coupled with 64MB DDR2 and an 8MB flash. It’s not the first low-cost router from the company, as the Banana Pi BPI-WiFi6 Mini was introduced this summer for $30 with Triductor TR6560 SoC, and with the Banana Pi BPI-WiFi5, they’ve now introduced a lower-end WiFi 5 router going for just about $16 plus shipping on AliExpress or $29.99 on Amazon. Banana Pi BPI-WiFi5 specifications: SoC – Siflower SF19A2890S2 dual-core MIPS processor @ 1.2GHz System Memory – 64MB DDR2 RAM Storage – 8MB flash Networking Switch – Airoha AN8855R Gigabit Ethernet switch 1x Gigabit Ethernet WAN port 3x Gigabit Ethernet LAN ports Wireless 2.4 GHz WiFi 2×2 MIMO up to 300 Mbps 5 GHz WiFi 2×2 MIMO up to 866.7 Mbps Frequency bands 2.4GHz – 2.4GHz […]

Giveaway Week 2024 – iKOOLCORE R2 Core i3-N300 mini PC and quad 2.5GbE router

Let’s end CNX Software’s Giveaway Week 2024 with a bang! The last prize is an iKOOLCORE R2 mini PC and router powered by an Intel Core i3-N300 Alder Lake-N CPU, equipped with 8GB RAM and a 512GB NVMe SSD, and featuring four 2.5GbE ports. The tiny PC also comes with HDMI and USB-C ports for dual 4K video output, an M.2 E-Key socket to install a wireless module for WiFi and Bluetooth, two USB 3.1 Gen 2 (5 Gbps) Type-A ports, a USB 3.1 Gen 2 (10 Gbps) Type-C port with DisplayPort Alt. mode, and a not-so-useful USB-C audio port using Realtek ALC987 codec. My review of the iKOOLCORE R2 last year was a learning experience as it was the first time I used Proxmox VE and pfSense, and since I wanted to use the system both as a mini PC running Ubuntu 22.04 desktop and a router/firewall running pfSense […]

Radxa E52C – A Rockchip RK3582 router with dual 2.5GbE, USB 3.0 port, USB serial console port

Radxa E52C is a compact router based on Rockchip RK3582 hexa-core Cortex-A76/A55 SoC and featuring two 2.5GbE ports, a USB 3.0 port, and a USB-C port for serial console access which will make some readers happy… It’s an update to the earlier Radxa E20C “Mini Network Titan” router, which was limited to two Gigabit Ethernet ports and a USB 2.0 port, and powered by an entry-level Rockchip RK3528A quad-core Cortex-A53 SoC. The Radxa E52C is better in every way with a much faster CPU, higher maximum memory and flash storage capacities, faster networking, and support for USB 3.0 storage or wireless dongles leading the company to call it an “Enhanced Mini Network Titan”. Radxa E52C specifications: SoC – Rockchip RK3582 CPU Dual-core Cortex-A76 with up to 2.4 GHz Quad-core Cortex-A55 at up to 1.8GHz GPU – None (all good since we are talking about a router here…) AI accelerator – 5 […]

iKOOLCORE R2 Max 10GbE mini PC review – Part 1: Unboxing, teardown, and first boot

Dual 10GbE Dual 2.5GbE Intel N100 mini PC soft router

iKOOLCORE R2 Max is an Alder Lake-N mini PC, server, and soft router equipped with two 10GbE and two 2.5GbE ports and offered with either an Intel Processor N100 quad-core CPU, or a more powerful Intel Core i3-N305 octa-core processor. When iKOOLCORE offered me an R2 Max sample for review, I explained I did not own any 10GbE networking gear. So the company decided to send me two samples for testing 10 Gbps Ethernet networking: a fanless Intel N100 model and an actively-cooled Core i3-N305 model. Since we’ve already gone through the specifications in the first article, I’ll start the iKOOLCORE R2 Max review with an unboxing, a teardown, and a first boot. In the second part of the review, I’ll use Proxmox, OpenWrt, Ubuntu, and/or other operating systems to test the devices using one as a DUT (Device Under Test) and the other as a 10GbE server. iKOOLCORE R2 […]
