Raspberry Pi Holdings Plc debuts on the London Stock Exchange

You may soon be greeted by a chart when searching for the stock of Raspberry Pi boards simply because Raspberry Pi Holdings Plc is now a public company listed on the London Stock Exchange (LSE) under the ticker RPI. The Raspberry Pi Foundation was founded in 2008 as a non-profit organization with Eben and Liz Upton (and others) taking a gamble manufacturing a few thousand Raspberry Pi model B boards for $35 apiece for the February 2012 launch. But things got quickly out of hand, and the unexpected success of the board meant Raspberry Pi Trading (then changed to Raspberry Pi Limited) for-profit had to be established to handle sales and retribute most of the profits to the non-profit entity. After having sold over 60  million Raspberry Pi boards, Raspberry Pi Limited is no more, following the listing of Raspberry Pi Holdings Plc. Since the company is now public, there’s […]

SONOFF Zigbee Bridge Ultra Review – eWelink app, Matter Bridge, Turbo Mode for extended range, and Home Assistant

We have received two more Zigbee smart home products from ITEAD to review. It appears that SONOFF has strategically introduced a variety of Zigbee devices in the first half of this year. The first one we will be reviewing is the SONOFF Zigbee Bridge Ultra, which we believe will eventually replace the Zigbee Bridge (2020) and Zigbee Bridge Pro (2022) and comes with additional features, such as being a Matter Bridge. The second device we’ve received is the SONOFF Micro Zigbee USB Adapter for which we’ll post a review in the next few days, But first, let’s dive into the SONOFF Zigbee Bridge Ultra review. Overview SONOFF Zigbee Bridge Ultra (Ultra for short and also called SONOFF ZBBridge-U) is a multi-functional device. Compared to its predecessor, the Zigbee Bridge Pro, the Ultra shows big improvements in features and hardware specs. It boasts a much more powerful chip (Rockship RV1109 vs. […]

GateMate Integrated Logic Analyzer (ILA) deep dive

CNXSoft: This is a guest article by Dave Fohrn, Embedded Software Engineer at Cologne Chip AG, that goes into detail about the company’s open-source integrated logic analyzer (ILA) for GateMate FPGA chips. A field-programmable gate array (FPGA) is a highly flexible integrated circuit in which complex logic circuits can be configured. They are often used as custom computing units in digital circuits because of their ability to process data quickly and in parallel using individually configured circuits. The digital circuits designed specifically for FPGAs are usually developed in a hardware description language such as Verilog or VHDL and are known as gateware. The term “gate” refers to the configurable digital logic units in the FPGA on which the individual gate circuits are implemented. An effective design can accelerate the computing process by strategically utilizing the various resources available in the FPGA, processing data in parallel, and intelligent implementing pipelining. A […]

GEEKOM A8 Review – Part 3: Ubuntu 24.04 tested on an AMD Ryzen 9 8945HS mini PC

We’ve already checked out GEEKOM A8 mini PC hardware with an unboxing and a teardown, before testing the AMD Ryzen 9 8945HS mini PC in Windows 11 Pro, and we’ll now report our experience with the GEEKOM A8 running Ubuntu 24.04 to see how it performs in Linux. We tested most features of the GEEKOM A8 mini PC on Ubuntu 24.04, ran several benchmarks to compare it to the similar GEEKOM A7 mini PC, performed storage and networking performance testing, ran stress test to check thermal performance, and measured fan noise and power consumption under various conditions. Installing Ubuntu 24.04 on the GEEKOM A8 mini PC As usual, we resized the Windows 11 partition to install Ubuntu 24.04 alongside Microsoft OS using a bootable USB flash drive created with the Ubuntu ISO. But you’ll notice BitLocker is enabled so the Ubuntu 24.04 installation can’t proceed. The installation wizard will ask […]

ThingPulse Pendrive S3 ESP32-S3 USB stick comes with 128MB of storage and a capacitive spring button

The Pendrive S3 is an ESP32-S3 development board in a USB stick enclosure with 128MB of flash memory and an unusual capacitive touch button. The Espressif ESP32-S3-MINI-1 module on the board integrates an Xtensa dual-core 32-bit LX7 microprocessor with support for 2.4GHz Wi-Fi and Bluetooth 5 (low-energy). The device features a capacitive touch button that can be used to trigger actions by touching the enclosure. The capacitive button isn’t visible on the exterior of the device, which helps the device maintain a low profile. You may be interested in Dani Eichhorn’s article on how he came up with the idea of using a spring for the capacitive touch button. The Pendrive S3 stick can be used as a BadUSB device for hacking and penetration testing purposes. With the aid of SuperWiFiDuck, it can perform keystroke injection attacks. All scripts can be managed and controlled wirelessly via a web interface, and […]

LattePanda Mu review – Part 1: an Intel N100 Compute Module tested with Windows 11, carrier boards with PCIe slots

Last April, DFRobot launched the LattePanda Mu x86 Compute Module powered by an Intel N100 Alder-Lake processor with 8GB RAM and a 64GB eMMC flash along with Lite and Full function carrier boards for evaluation. End customers will typically design their own carrier board without having to take of high-speed signals for the LPDDR5 memory and other complexities during the PCB layout. DFRobot has sent us the LattePanda Mu module for review along with the Lite and Full Function carrier boards, a heatsink for passive cooling, and an active cooler so we can compare both cooling solutions.  Let’s have a look at the LattePanda Mu module and accessories before testing the kit with the Windows 11 operating system, including the PCIe x4 slot. LattePanda Mu kit unboxing The parcel included three retail boxes. The smallest box housed the LattePanda Mu Compute Module, a heatsink, and an active cooler. The second […]
