Top 5 most powerful Arm SBC’s & Devkits in 2021

Most Powerful Arm SBCs development kit 2021

While companies like Hardkernel, Raspberry Pi, Orange Pi, and FriendlyArm offers affordable, great little Arm Linux development boards that are suitable for many projects, in some cases, your requirements may lead you to spend a bit more for either extra CPU power, more memory, AI processing power, faster I/Os and so on. That’s why I did a list of the most powerful Arm single board computers in late 2017, but with over three years passed since then an update is warranted. The boards from the list must be easily purchasable from individuals (with the cash to spare) or small companies, so we’ll exclude hard-to-source hardware, as well as Arm server boards like Ampere eMAG motherboard, that do not really qualify as single board computers. Snapdragon 888 Mobile Hardware Development Kit While there are plenty of Cortex-A72/A73 development boards around, it’s much hardware to find one with more recent Cortex-X1 or […]

$30 Raspberry Pi CM4 IoT Router Carrier Board Mini offers Dual Gigabit Ethernet

We’ve recently written about Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4” that offers dual Gigabit Ethernet, and two USB 3.0 ports for software router applications, but it can also be used for IoT, Smart Home, and camera projects, as well as HTPC maker thanks to micro HDMI output and MIPI DSI/CSI connector. It is sold for an affordable $45, exceeding the Raspberry Pi CM4 module. But if all you want to do is get a dual Gigabit Ethernet WiFi router or IoT gateway, DFRobot has now introduced a more compact and cheaper carrier board for Raspberry Pi CM4: “Compute Module 4 IoT Router Carrier Board Mini“. CM4 IoT Router Board Mini specifications: Compatible Module – Raspberry Pi Compute Module 4 / 4 Lite with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB flash, optional 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0 […]

FOSDEM 2021 Online February 6-7 – Hardware, Embedded & IoT talks

FOSDEM is an open-source developer event that takes place on the first week-end of February every year in Brussels, Belgium. Every year except this year, as due to COVID-19 restrictions, FOSDEM 2021 will take place online like most events these days. The schedule has been up for some time, and today I’ll look at some of the interesting talks mostly from the Embedded, Mobile and Automotive “virtual devroom” but also other tracks. Saturday, February 6, 2021 13:00 – 14:00 – From Reset Vector to Kernel – Navigating the ARM Matryoshka Long gone are the times of executing the OS in-place from memory-mapped flash upon reset. A modern SoC now comes with complex mask ROM firmware, with driver, filesystem, protocol and crypto support for loading… yet another bootloader. In his talk, Ahmad follows this chain of bootloaders until the kernel is started, stopping along the way for RAM setup, peripherial initialization, […]

Build a Raspberry Pi CM4 4-Bay NAS with Wiretrustee Carrier board

Wiretrustee SATA board Raspberry Pi Compute Module 4

Broadcom BCM2711 processor comes with a PCIe interface that is used for the USB ports on the Raspberry Pi 4 SBC, but that is exposed through the board-to-board connectors of Raspberry Pi Compute Module 4, aka Raspberry Pi CM4, and allows all sort of designs. So far we’ve mostly seen this PCIe interface used for M.2 expansion slots on devices ranging from industrial computers to carrier board such as Piunora or Gumstix Raspberry Pi CM4 development board. But Wiretrustee had a different idea and designed carrier board with Marvell 88SE9215 PCIe to SATA controller and offering four SATA connectors to build a 4-bay NAS with Raspberry Pi CM4 module. Wiretrustee carrier board specifications: Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite Storage 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) chip tested at a write speed of ~220MB/s […]

ClusBerry 9500-CM4 – A Raspberry Pi CM4 cluster, industrial style

ClusBerry Industrial Raspberry Pi CM4 Cluster

Raspberry Pi cluster boards / solutions pop-up from time to time. But so far, I think we’ve seen only one based on Raspberry Pi CM4 modules with the upcoming Turing Pi 2 mini-ITX cluster board supporting four of those. TECHBASE has now unveiled a different kind of Raspberry Pi CM4 cluster with ClusBerry 9500-CM4 integrating up to eight Raspberry Pi Computer Module 4 in a DIN-Rail housing for industrial applications. ClusBerry 9500-CM4 is designed to be customizable with a choice of Raspberry Pi CM4 based modules and I/O cards: Standard 9500-CM4 cluster module with Compute Module 4 and a selection of configuration that include: I/O Controller with DI, DO, AI, 1-Wire, RS-232/485 and CAN interfaces Communication Gateway with up to 2x Ethernet, serial ports, wireless connectivity: LTE-cat.M1, 4G, 5G, LoRa, ZigBee, Z-Wave, Wireless M-Bus AI Gateway with Coral Edge TPU via PCIe M.2, or up to 4x Coral Edge TPU […]

H2 Net Card adds four 2.5 GbE ports to ODROID-H2/H2+ SBC

ODROID-H2+ is already a cool single board computer with an Intel Gemini Lake Refresh processor, up to 32GB RAM, dual 2.5GbE networking, support for SATA and NVMe storage, dual 4K video output, and more. But in recent days, I’ve read people complaining recently announced WiFI 6 or WiFi 6E routers only had one 2.5 Gbps or 5 Gbps Ethernet jack and wanted all/more RJ45 connectors to be 2.5 GbE ports or greater. But if even the two 2.5GbE ports on ODROID-H2+ are not quite enough for your needs, Hardkernel H2 Net Card triples that amount by adding four extra 2.5 GbE to the x86 SBC. It also works on ODROID-H2, meaning you’d get the existing dual Gigabit Ethernet ports, plus the four 2.5GbE ports from the M.2 card. There’s no much in the way of specifications for H2 Net Card: 4x Ethernet ports up to 2.5 GbE via RTL8125 controller. […]

Forlinx OK1028A-C networking SBC supports LVDS displays, 4G/5G modules

Forlinx released two networking SBC’s with 10Gbps Ethernet powered by NXP LS1043A and LS1046A processor nearly exactly one year ago. Like many other networking SBCs they do not come with video output so configuration is done via a computer or laptop either through a UART interface or a web interface. But in some cases, such boards may be integrated into machines that require a display for human-machine interaction. That’s why Forlinx has now released a new networking board – OK1028A-C – powered by NXP QorIQ Layerscape LS1028A dual-core Cortex-A72 processor that natively supports video output up to 4K UHD resolution via an eDP/DisplayPort interface which the company used to provide an LVDS header. The board also offers 5 Gigabit Ethernet ports, as well as optional WiFi, Bluetooth, and 4G or 5G cellular connectivity via M.2 and mPCIe modules. Forlinx OK1028A-C specifications: FET1028A-C system-on-module SoC – NXP LS1028A dual-core Cortex-A72 processor […]
