Low-power satellite IoT SoC works with Totum’s Low Earth Orbit (LEO) network

Totum LEO Satellite IoT Network

Orca Systems ORC3990 is a low-power satellite Internet of Things (IoT) SoC that works with Totum’s Low Earth Orbit (LEO) network of satellites and targets outdoor and indoor tracking and monitoring applications. It’s not the first time we read about satellites being used for LPWAN networks, as Sigfox launched LEO satellites a few years ago to provide worldwide coverage even in remote locations like the Sahara desert, the two poles, and oceans. But I had never heard of Totum or Orca Systems before, so let’s have a closer look. Orca Systems ORC3990 ORC3990 specifications: Unnamed Arm cores Integrated RF Transceiver Low Power Sensor-to-Satellite (LP-S2S) connectivity in the 2.4 GHz ISM band Totum DMSS modem for improved doppler performance Link budget enables indoor signal coverage Support location fixes with 20m accuracy Low power – 10+ year battery life Package – 7x7mm QFN chip Temperature Range – -40 – +85°C Process – […]

Fixing performance issues with Realtek RTL8156B 2.5GbE USB dongle in Ubuntu

cdc_ncm vs r8152 drivers ubuntu

A few days ago, I reviewed a USB 3.0 to 2.5 Gbps Ethernet adapter based on Realtek RTL8156B chip in Ubuntu 20.04, and let’s say the reliability and performance were underwhelming. I got some recommendations like changing cables, the MTU size, etc… Playing around with cables did no help, but one comment mentioned the cdc_ncm driver could be the issue, followed by another saying that updating to Linux kernel 5.14 should install the correct r8152 driver… So I just did that:

This upgraded Linux 5.13 (shipped with Ubuntu 20.04 + HWE) to Linux 5.14, but still no luck as the system kept using the cdc_ncm driver with a half-duplex link:

But then I thought I may have to use udev rules to prevent loading the cdc_ncm driver, and there’s indeed 50-usb-realtek-net.rules in r8152 driver to do just that. So I copied the file in /etc/udev/rules.d/ folder. Since I […]

Intel aims to be the performance per watt leader by 2024 with Lunar Lake processors

Intel Roadmap to 2024 and beyond

Apple-designed Arm processors have shown it’s possible to get high-performance at relatively low power, and this has left competitors behind in that regard. But Intel aims to rectify that with the goal of becoming the “performance per watt leader” by 2024 with the new Lunar Lake processors manufactured with Intel 18A process. Intel also provided some details about families following Alder Lake processors with Raptor Lake expected later this year, Meteor Lake and Arrow Lake based on Intel 4 and 20A processes in 2023-2024 2022, and Lunar Lake expected in 2024+. Let’s have a look at what we know so far for each family. Intel Raptor Lake The Raptor Lake processors will rely on the same “Intel 7” process as Alder Lake processors, offer up to double-digit performance boost (translation: up to around 10% in specific workloads), up to 24 cores and 32-threads, better overclocking, support for AI M.2 modules […]

HC32L110 Arm Cortex-M0+ MCU is available in a tiny 1.59 x 1.436 mm CSP16 package

HC32L110 CSP16 Arm MCU

Before you ask… No, it’s not another one of those CNXSoft’s typos, I did not mean to write cm (centimeters), and HDSC HC32L110 is indeed an Arm Cortex-M0+ microcontroller available in an almost microscopic 1.59 x 1.436 mm CSP16 package, which could make it the world’s smallest Arm MCU. I discovered the microcontroller when LilyGO shared a small board only showing the MCU’s dimensions and CSP16 type. Silicon Labs EFM8SB10F8G-CSP16 showed first in a web search, but that’s an 8-bit 8051 microcontroller with a 1.781 x 1.659 mm CSP16 package, and it’s unlikely they’d use a “Western” microcontroller. But I soon found the microcontroller on Huada Semiconductor Co. Ltd (HDSC) website. HC32L110 specifications: MCU core – Arm Cortex-M0+ 32-bit core @ up to 32 MHz Memory – 2KB to 4KB RAM memory with parity check Storage – 16K to 32KB flash memory with erase and write protection Peripherals 16x GPIOs […]

USB 3.0 to 2.5Gbps Ethernet adapter review

USB to LAN 2.5 Gigabit Ethernet Adapter

Late last month, I received hardware to test 2.5GbE and WiFi 6 with namely a Radxa E25 SBC, Xiaomi AX6000 WiFi 6 router, and an 8-port TP-Link 2.5GbE switch. I intended to start testing 2.5GbE networking with UP Xtreme i11 mini PC and Radxa E25, but I thought it might be a good idea to get a USB 3.0 to 2.5Gbps Ethernet adapter just in case. I purchased a no-name dongle for under $15 (475 THB on Lazada) in Thailand, but a USB 3.0 dongle that looks exactly the same can also be purchased on Aliexpress with either a USB Type-A port or a USB Type-C port. There’s some issue with Radxa E25 (it won’t boot it), so I ended up testing the dongle with UP Xtreme i11 mini PC.

Beelink GTR5 Review – An AMD Ryzen 9 mini PC tested with Windows 11, Ubuntu 20.04

Beelink GT5 Review AMD Ryzen 9 mini PC

Beelink’s GTR5 is their most powerful mini PC to date and has been released as part of their ‘GT’ series of slightly larger mini PCs that are notable for expandable storage configurations together with multiple ports and characterized by the inclusion of a fingerprint scanner. Featuring an AMD Ryzen 9 mobile processor with Radeon Graphics, Beelink kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu. Hardware Overview The Beelink GTR5 physically consists of a 168 x 120 x 39mm (6.61 x 4.72 x 1.54 inches) rectangular metal case. As an actively cooled mini PC, it uses AMD’s ‘Zen 3’ Ryzen 9 5900HX processor which is an eight-core 16-thread 3.3 GHz mobile processor boosting up to 4.6 GHz together with Radeon Graphics. The front panel has an illuminated power button, a ‘CLR CMOS’ button, a USB 3.1 port, a Type-C USB 3.1 port, and a […]
