Orange Pi Zero-LTS Allwinner H2+ SBC Gets More Efficient and Cooler

Allwinner H2+ SBC Low Power Consumption

Orange Pi Zero is a cool little Arm Linux board based on Allwinner H2+ processor for headless applications requiring WiFi and/or Ethernet that was first launched in November 2016 for $7 and up. It was not launched without controversy, as first users had various issues with the Allwinner XR819 WiFi module, but I had no such problem when I made an Orange Pi Zero Google Assistant smart speaker. Nevertheless, Shenzhen Xunlong Software is about to launch a newer version of the board – Orange Pi Zero-LTS -, with the same specifications, but improvements in the design in order to reduce power consumption, and lower the board’s temperature. As the name implies, the company will commit to long term support (i.e. long term availability) for the board, but they did not tell me for how many years. Orange Pi Zero-LTS v1.5 specifications: SoC – Allwinner H2+ quad-core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU @ 600 MHz System Memory …

Amlogic S905X2 vs S905X3 – Features Comparison

Amlogic S905X2 vs S905X3

Despite Arm claiming Cortex-A55 core would bring some performance improvements, we’ve recently seen actual Amlogic S905X3 benchmarks show the performance compared to Amlogic S905X2 Arm Cortex-A53 is almost identical (3% improvement for S905X3 CPU, 9% for the GPU). So Amlogic S905X3 TV box processor must differentiate itself from its predecessor by its additional features, and while we published the detailed specifications of Amlogic S905X3 processor a few months ago, we did not provide a side-by-side comparison table just yet. So here’s one courtesy of SDMC (with some corrections). SoC Amlogic S905X2 Amlogic S905X3 CPU 4x Arm Cortex-A53 @ 1.80 GHz 4x Arm Cortex-A55 @ 1.91 GHz Neural Network Accelerator N/A Optional 1.2 TOPS NNA GPU Mali-G31 MP2 with OpenGL ES 3.2, Vulkan 1.0, and OpenCL 2.0 Always-on MCU Cortex-M3 & Cortex-M4 (Optional ) Cortex-M3 & Cortex-M4 DDR DDR3-2133 /DDR3L-2133 / DDR4-2666 /LPDDR3-2133 /LPDDR4-3200 SDRAM up to 4G DDR3-2133 /DDR3L-2133 / DDR4-3200 /LPDDR3-2133 / LPDDR4-3200 SDRAM up to 4G Video Decoding H.265, …

Icarus IoT Board Features nRF9160 GPS + NB-IoT SiP in Adafruit Feather Form Factor

The new Icarus IoT board from Actinius, uses the Nordic nRF9160 SiP, a powerful yet low power system in a package designed for use with GPS and LTE-M & NB-IoT cellular data, also found in Ruuvi node which we covered a few months ago. The board’s purpose is for mobility and ease of project tracking anywhere, and can be found in application scenarios such as fleet management and security, cargo tracking, or asset monitoring, and many more. The board has power inputs for solar panel, USB or LiPo/Li-Ion Battery, which widens the boards mobile nature, and on-site, in-the-field capability. Since the form factor follows Adafruit Feather, the Icarus board benefits of additional component options for prototyping and DIY electronics projects. The nRF9160, by Nordic Semiconductor, is a SiP (System in a Package) that carries an extensive line of embedded software and hardware. As we had reported the nRF9160 SiP low-power IoT solution consists of a global multimode LTE-M/NB IoT modem, …

Checking Out Machine Check Exception (MCE) Errors in Linux

Machine Check Exception Error Linux

I recently reviewed ODROID-H2 with Ubuntu 19.04, and noticed some errors messages in the kernel log of the Intel Celeron J4105 single board computer while running SBC-Bench benchmark: I did not know what do make of those errors, but I was told I would get more details with mcelog which can be installed as follows: There’s just one little problem: it’s not in Ubuntu 19.04 repository, and a bug report mentions mcelog is not deprecated, and remove from Ubuntu 18.04 Bionic onwards. Instead, we’re being told the mcelog package functionality has been replaced by rasdaemon. But before looking into the utilities, let’s find out what Machine Check Exception (MCE) is all about from ArchLinux Wiki: A machine check exception (MCE) is an error generated by the CPU when the CPU detects that a hardware error or failure has occurred. Machine check exceptions (MCEs) can occur for a variety of reasons ranging from undesired or out-of-spec voltages from the power supply, …

Ameba Z2 IoT Board Features Realtek RTL8720CM Armv8-M KM4 Secure Wireless MCU

Ameba Z2 IoT Development Board

In 2016 we discovered Realtek Ameba wireless microcontrollers combining an Arm Cortex-M3 core with WiFi connectivity, and that could potentially become an ESP8266 competitor with modules selling for as low as $2. But the solution never really took off, because it was about the same price as ESP8266, and the latter already had a solid software ecosystem and community. But RealTek has now introduced a new Ameba Z2 IoT development board powered by RTL8720CM microcontroller featuring an Armv8-M KM4 core clocked at 100 MHz. What’s an Arm KM4 core you may ask? Seeed Studio informed me Arm and RealTek worked together on the KM4 core, so it looks like a custom Armv8-M microcontroller. Ameba Z2 IoT Development Board Ameba Z2 (ZII) specifications: Wireless MCU – Realtek RTL8720CM single core Armv8-M KM4 core @ 100MHz with 4.2MB internal RAM, WiFi and Bluetooth radios Storage – 2MB external flash on module Connectivity Wi-Fi – 802.11 b/g/n 1×1 Wi-Fi 4 (20/40MHz) with PCB …
