LicheePi 3A – A SpacemIT K1 RISC-V development board with SoM and carrier board

Sipeed LicheePi 3A is a development board comprised of the LM3A system-on-module based on SpacemIT K1 octa-core RISC-V SoC and the same baseboard as found in the earlier LicheePi 4A equipped with a T-Head TH1520 quad-core RISC-V “LM4A” system-on-module instead. The LicheePi 3A is currently offered with a 32GB eMMC flash and 8GB or 16GB LPDDR4x memory. The carrier board provides a microSD card, two M.2 PCIe sockets for storage or other expansion, two gigabit Ethernet ports, a WiFi 6 and Bluetooth 5.2 module, HDMI and MIPI DSI display interfaces, two MIPI CSI camera interfaces, four USB 3.0 ports, and a 20-pin GPIO header for expansion.

DietPi 9.7 and Armbian 24.8 released with improved support for Rockchip, Amlogic, and Allwinner SBCs

Armbian and DietPi are two separate projects that provide Linux-based OS images optimized for Arm-based single board computers. The last time we had a look at both projects was in June with the release of Armbian 24.5.1 and DietPi 9.4, but there have been several updates since then including the releases of the latest DietPi 9.7 and Armbian 24.8 Yelt just a few days ago. So let’s check out the latest changes. DietPi 9.7 DietPi is a lightweight Debian-based Linux distribution for SBCs and server systems that ships as a minimal image but users can install any packages they want, including the ones required for desktop environment, to match the requirements of the applications. It’s notably used by the Linamp project – a Raspberry Pi 4-based project that brings WinAMP to real life – that we covered a few weeks ago. DietPi 9.7 was released on August 25, 2024 with […]

xMEMS XMC-2400 is a 1mm-thin solid-state micro cooling fan-on-a-chip for ultrathin devices and SSDs

xMEMS Labs XMC-2400 is a vibration-free, solid-state micro cooling fan-on-a-chip that’s just 1mm thin and designed to cool the processor, other chips, and batteries on space-constraints devices such as smartphones, tablets, extended reality headsets, laptops, as well as SSDs. The XMC-2400 can deliver up to 39cc/sec airflow and up to 1,000Pa back pressure per instance while remaining inaudible and only consuming an estimated 30mW. It’s also rated IP58 for water and dust resistance. It leverages the manufacturing process the company has been using for its ultrathin MEMS speakers. xMEMS XMC-2400 specifications: Top-venting and side-venting packages for flexible integration in different system form-factors Bi-directional flow rate, adjustable up to 39cc/sec Inaudible; all mechanical operation is at ultrasonic frequencies Power consumption – 30mW (estimated) Dimensions –  9.26 x 7.6 x 1.08 mm Weight – 150 mg SMT-reflowable Ingress Protection – IP58 Two packages will be offered: XMC-2400-S – Side-Vented Package supports chip-stacking […]

AgroSense LoRaWAN Sensor Review

Review of AgroSense LoRaWAN Smart Agriculture sensors with the SenseCAP M2 LoRaWAN gateway

Today, I will be reviewing the AgroSense LoRaWAN sensors from Makerfabs designed for high-precision agriculture. This time, I received four sets of sensors designed for measuring environmental data and a Seeed Studio SenseCAP M2 LoRaWAN gateway. Below is the list of items I received. AgroSense LoRaWAN Barometric Pressure Sensor – Measures the barometric pressure in a 300 to 1100 hPa range with ±0.12 hPa accuracy and 0.01 hPa resolution. AgroSense LoRaWAN Light Intensity Sensor – Measures the light intensity in a 1 to 65535 lx range with ±1 lx accuracy and ±20% resolution. AgroSense LoRaWAN Temperature & Humidity Sensor – Measures temperature and humidity in the atmosphere in the ranges of -40°C to 85°C and 0 to 100 %RH with accuracy of ±0.2°C and ±0.2% RH respectively. AgroSense LoRaWAN Industrial Temperature Sensor – Measures temperature in the industrial high-temperature environments in the -60°C to 200°C range with ±0.1°C accuracy and […]

Linux 6.10 Release Changelog

Linux 6.10 Release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux Torvalds has announced the release of Linux 6.10 on LKML: So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized. In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary. Another third was drivers, and the rest is “random”. Anyway, this obviously means that the merge window for 6.11 opens up tomorrow. Let’s see how that goes, with much of Europe probably making ready for summer vacation. And the shortlog below is – as always – just the last week, not some kind […]

Cincoze DS-1402 review: Part 3: Ubuntu 24.04 tested on an Intel Core i9-12900E embedded system

In part one of the Cincoze DS-1402 review, I checked out the hardware of the modular rugged computer before testing the Intel Core i9-12900E embedded computer with Windows 11 Pro in the second part, and I’ve now had time to test the Cincoze DS-1402 embedded system with Ubuntu 24.04. I’ve tested most features in Linux, ran some benchmarks, evaluated the gigabit Ethernet performance of some of the ten Ethernet ports, checked CPU temperature under a stress test with and without the fan, measured power consumption, and more. Ubuntu 24.04 system information I installed Ubuntu 24.04 with the official x86_64 ISO in dual boot configuration with Windows 11 Pro. The installation process was smooth, and I have nothing specific to report here. Going to the Settings->About window confirms we have a CINCOZE-DS-1400 system (DS-1402 is part of the DS-1400 family) with a 24-thread 12th Gen Intel Core i9-12900E processor and 64GB […]

Cincoze DS-1402 review – Part 2: An Intel Core i9-12900E embedded computer tested with Windows 11 Pro

I’ve already checked out the hardware of the Cincoze DS-1402 modular embedded computer in the first part of the review with an unboxing and teardown of the Intel Core i9-12900E computer that ships with expansions such as an NVIDIA GTX 1630 graphics card held in place with a patented solution and two CMI expansion modules with four gigabit Ethernet ports each. I’ve now had more time to test the Cincoze DS-1402 with Windows 11 Pro, so I’ll report my experience with the system in the second part of the review checking out system information, testing features, running benchmarks, evaluating networking and storage performance, testing the thermal design, and taking measurements for fan noise and power consumption. I’ll also compare some of the second to the GEEKOM XT12 Pro mini PC powered by an Intel Core i9-12900H SoC since embedded SKUs – like the Core i9-12900E – are usually slightly slower […]
