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 […]

Checking Out Machine Check Exception (MCE) Errors in 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:

[180422.405294] mce: [Hardware Error]: Machine check events logged

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:

sudo apt install mcelog

1	sudo apt install mcelog

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 Instead, we’re being told the mcelog package functionality has been replaced by rasdaemon.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 […]

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

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 […]

PicoLog 6 Beta supports Raspberry Pi 4, 3B and 3B+

One of the most popular computer platforms, Raspberry Pi has not been supported for Pico’s advanced datalogging software, up until now. The PicoLog 6 datalogging software is now compatible with Raspbian Stretch or later OS. The software has been designed for quick access to simple or complex acquisitions, and enabled to record, analyze or view data of almost any type. TC-08 Thermocouple Datalogger with Raspberry Pi 3 board Real Power It is essentially the same software that runs on Windows, macOS, and Linux, with a few differences to take advantage of the capability of the lower-powered Arm processors. Producing a powerful datalogger for the Raspberry Pi SBC platform. The PicoLog 6 is optimized for Raspbian Stretch and runs the Raspberry Pi 4, 3B and 3B+ SBC’s. The core of the utility is an easy to use visual interface that allows for an almost out-of-box use to the program. Features Making […]
