  • New SecurStor microSD Cards Support ARM Raspbian Linux

    In response to the growing need for data protection, ATP Electronics, the global leader in specialized storage and memory solutions, has launched the SecurStor microSD cards – the latest in its line of secure NAND flash storage products for the Internet of Things (IoT), education, automotive, defense, aerospace and other applications requiring confidentiality and reliability.

    “Removable storage media such as microSD cards provide great convenience and versatility for storing and transporting data. However, such convenience also exposes them to risks of unauthorized access,” said Chris Lien, ATP Embedded Memory Business Unit Head. “In many instances, the boot image may be compromised, corrupting the operating system or rendering the system unusable. Malware may be introduced, or private information may be disclosed and used for damaging intents. Amidst such dangerous scenarios, we have made security a key priority for all ATP products.”

  • RK3566 & RK3568 processors to get Linux mainline support soon

    Rockchip RK3566 & RK3568 processors were just officially announced at the end of the year, and soon followed with announcements of related such as Core-3568J AI Core system-on-module, some Android 11 TV boxes, Station P2 mini PC, and RK3566/RK3568 development boards.

    But it did not take long, as RK3566/RK3568 are about the get support for mainline Linux, with engineers from Collabora and Rockchip having recently committed preliminary support for RK356x platforms, notably using Pine64 Quartz64 SBC for testing.

  • Perf-V Beetle board features GAP8 multi-core RISC-V AI MCU

    GreenWaves Technologies introduced the GAP8 low-power RISC-V IoT processor optimized for artificial intelligence applications in 2018. The multi-core (8+1) RISC-V processor is especially suitable for image and audio algorithms including convolutional neural network (CNN) inference.

    The same year, the company launched the GAPUINO development kit that sold and (still sells) for $229 with QVGA camera and a multisensor board with four microphones, an STMicro VL53 Time of flight sensor, an IR sensor, a pressure sensor, a light sensor, a temperature & humidity sensor, and a 6-axis accelerometer/gyroscope. But there’s now a much more affordable solution to evaluate GAP8 multi-core RISC-V MCU with PerfXLab Perf-V Beetle board.

  • The Axon platform offers WiFi & LoRa IoT messaging in a compact form factor (Crowdfunding)

    The board can be programmed with Python (MicroPython?), plot graphics with Matlab, control up to four relays, and integrate with Axon Cloud apps. As I understand it, the MCU – USB switch selects the source of the data: either USB or UART.

    There are already many ESP8266 boards around, so Axon is probably mostly interesting when connected with a LoRa module as it offers an ultra-compact WiFi + LoRa IoT solution.

  • Check LoRaWAN deployments on the go with WisGate Developer Base USB dongle

    RAKWireless just had their “Big Tech Bloom” event services they announced many new LPWAN products ranging from WisDM fleet management system, OpenWrt based Wisgate OS, new industrial LoRaWAN gateways like WisGate Edge Lite 2, their first STM32WL module, as well as 9 new modules for WisBlock modular IoT platform with MIC, e-Paper display, GPS, an ESP32 based WisBlock core, etc…

    But today, I’ll have a look at the new $99 WisGate Developer Base, a USB dongle that connects to a laptop for LoRaWAN networks evaluation, for example, to check the coverage before installing a new gateway. Alternatively, it could also be used to add LoRaWAN gateway capability to existing embedded hardware like routers or industrial PCs.

  • LoRaWAN BACnet gateway uses Raspberry Pi CM3+ for building automation

    A few years about we wrote about BASpi I/O Raspberry Pi HAT compatible with BACNet, a data communication protocol for Building Automation and Control Networks, also known as the ISO 16484-6 standard, and used for HVACs, lightings, elevators, fire safety, and other systems found in buildings.

  • A first look at Allwinner D1 Linux RISC-V SBC and Processor

    Last year, we reported that Allwinner was working on an Alibaba XuanTie C906 based RISC-V processor that would be found in low-cost Linux capable single board computers selling for as low as $12.

    The good news is that we won’t have to wait much longer as Allwinner D1 RISC-V processor is slated for an announcement next week, and a business card-sized SBC, also made by Allwinner, will become available in May. Some of the information is already available to developers in China, and CNX Software managed to obtain information about the Linux RISC-V SBC and Allwinner D1 processor.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
