QMiroPlus-201W – Arm router and Intel NAS in one device with Qualcomm IPQ4019 & Celeron J4125

QNAP QMiroPlus-201W is an unusual networked storage device that’s acting both as a 2.5GbE & WiFI 6 router and NAS combining Qualcomm IPQ4019 Arm SoC for the router functions, and an Intel Celeron J4125 quad-core Gemini Lake processor for the NAS functions. Usually, you’d get the choice of either an Arm or Intel processor, but here QNAP decided to use both to keep the same performance as having separate Arm-based router and Intel-based NAS, but in a much more compact form factor. QNAP QMiroPlus-201W hardware specifications: SoC/memory/internal storage For router SoC – Qualcomm IPQ4019 quad-core Arm Cortex A7 @ 716.8MHz Memory – 512MB DDR3 Internal Storage – 4MB SPI NOR Flash & 4GB eMMC flash For NAS SoC – Intel Celeron J4125 quad-core Gemini Lake processor @2.0 GHz Memory – 4GB DDR4 Internal Storage – 4GB eMMC flash Data Storage – 2x 2.5-inch SATA 3Gb/s (Compatible with 6Gb/s SSD/HDD) bay Networking […]

DIY Raspberry Pi Compute Module 4 NAS supports up to four drives

We previously noted it was possible to build a Raspberry Pi CM4 NAS using Wiretrustee carrier board with a built-in Marvell 88SE9215 PCIe to SATA controller and four SATA connectors. But Mebs just created his own Raspberry Pi Compute Module 4 four-bay NAS with his own carrier board equipped with a PCIe socket used to insert a PCIe SATA card, as well as a neat 3D printed enclosure that took 6 days to print. This carrier board design is actually derived from the official Raspberry Pi CM4 IO board with only the interfaces needed for the NAS to make it smaller and fit within the width of a standard 3.5″ hard drive. It was also made as simple as possible because it was Mebs’ first PCB design. This leaves the board with Gigabit Ethernet, one HDMI port, a USB 2.0 port, the PCIe 2.0 socket, as well as some headers […]

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 […]
