Linux 5.14 Release – Main changes, Arm, MIPS, and RISC-V architectures

Linus Torvalds has just announced Linux 5.14 release which happens to almost coincide with the anniversary of the initial announcement of the “small” project on August 25, 1991, about 30 years ago. Here’s Linux 5.14’s announcement: So I realize you must all still be busy with all the galas and fancy balls and all the other 30th anniversary events, but at some point you must be getting tired of the constant glitz, the fireworks, and the champagne. That ball gown or tailcoat isn’t the most comfortable thing, either. The celebrations will go on for a few more weeks yet, but you all may just need a breather from them. And when that happens, I have just the thing for you – a new kernel release to test and enjoy. Because 5.14 is out there, just waiting for you to kick the tires and remind yourself what all the festivities are […]

LibreELEC 10.0 minimal Linux OS for media playback released with Kodi 19.1

While most TV boxes and SBCs nowadays ship with or support a version of Android, people who just want the best viewing experience may prefer to switch to a Linux distribution such as LibreELEC or CoreELEC. The good news is that LibreELEC 10.0 has just been released with Kodi 19.1 and Linux 5.10 LTS. LibreELEC 10.0 is said to work well for Allwinner, Rockchip, and “Generic” Intel/AMD devices, while the Raspberry Pi 4 release’s codebase is rather new, and there may still be a few rough edges. Support for the previous generation Raspberry Pi boards has been dropped, and there’s no support for Amlogic platforms as CoreELEC already provides good support. Since LibreELEC 10.0 is based on Kodi 19.1, it benefits from the same features as Kodi 19 “Matrix” release including AV1 video decoding, a new skin, HDR support, and more. LibreELEC 10.1 support a wide range of single board […]

Coin cell-powered OpenThread sensor board can send data every 20 seconds for three years

Monkey Store’s Thread Sensor Tag is a pressure, humidity, temperature, and light sensor that connects to the OpenThread network, and is capable of transmitting MQTT/UDP data every 20 seconds over a period of around three years from a single coin cell battery. As a reminder, OpenThread is an implementation of the Thread IoT network protocol that was unveiled in 2016 by Nest Labs (now Google/Alphabet). This has not been widely used so far, but we did write about MKR SharkyPro development board with OpenThread support via STMicro STM32WB5MMG wireless module earlier this year, and Monkey Store is telling us both Google and Apple are working on devices with support for the IoT protocol. Thread Sensor Tag specifications: Wireless module – Minew MS88SF2 based on Nordic Semi nRF52840 multi-protocol 2.4GHz wireless Cortex-M4 microcontroller Sensor VEMLS6030 I2C light sensor MS8607 pressure, humidity, and temperature sensor I/Os – 7x through holes with Tx/Rx, […]

Overview and List of System-on-Module and Computer-on-Module Standards – Q7, SMARC, COM HPC, and More

A System-on-Module (SoM), also known as a Computer-on-Module (CoM), is a small board with the key components of a computer such as SoC, memory, and possibly others components such as PMIC (Power Management IC), an Ethernet PHY, as well as one or more connectors used to connect to a baseboard, also called carrier board, which features standard ports such as Ethernet (RJ45), USB ports, SATA, power jack and so on. The advantages of using of baseboard + SoM design compared to a single board are at least twofold: Most of the PCB design complexity is often around the CPU/SoC and high-speed buses connected to the CPU/SoC. So you could buy an SoM, design your own baseboard and get a complete design relatively in a short amount of time, with reduced development resources and costs. The design is modular, so you could easily upgrade from one SoM to another one. For […]

PC-based Logic Analyzers Comparison: PGY-LA-EMBD vs Logic16 Pro vs SP209

Building an embedded system requires multiple devices to communicate with the central processor, generally through an SPI or I2C bus. If your system is quite complex and things don’t work out as expected, then a Logic Analyzer might save your day. So, choosing the correct Logic Analyzer is critical to a successful project. This article gives a PC-based Logic Analyzers comparison, and we’ll compare products from three companies: Prodigy Technovations, Saleae, and Ikalogic. Factors to keep in mind while selecting a Logic Analyzer Before we dive into the comparison part, we should be aware of a few points based on which we’ll compare them. Logic analyzers come with a certain number of channels. The higher the number of channels is, the costlier is the product. So, select the number of channels appropriately depending on the size of your project. Several other technical specifications should also be considered, which are listed […]

TI AM64x 7-core processor is made for PLC’s, motor drives, industrial robots

Texas Instruments AM64x is a family of 64-bit Arm processors with functional safety designed for Programmable Logic Controllers (PLC), motor drives, remote I/O, and industrial robots. The top-end processor of the family, AM6442, comes with seven cores including two Cortex-A53 application cores, four Cortex-R5F real-time cores, and one Cortex-M4F isolated core. AFAICT, while the documentation is dated January 2021 and TI announced the processor in February in a blog post with a cryptic title, it was only first picked up by Embedded Computing in early May. Besides the processor itself, TI also provides an AM64x starter kit and a full-featured AM64x evaluation kit, and several companies are already preparing development boards and modules as we’ll see further below. TI AM64x processor AM64x key features & specifications: CPU cores Dual-core Arm Cortex-A53 processor @ 1.0 GHz with 256KB L2 shared cache with SECDED ECC, 32KB L1 D-cache, 32KB L1 I-cache Up […]

BastWAN Feather-compatible LoRaWAN board features RAK4260 Microchip R34 module

We’ve previously written about a Feather-compatible LoRaWAN board equipped with RAK4260 module based on Microchip R34 LoRa SIP called Penguino Feather. It appears somebody, namely Electronic Cats based in Mexico, decided to design an almost identical board with BastWAN. Let’s see if there are any differences besides the cheaper price. BastWAN specifications: LoRa module – Rak wireless RAK4260 module with: SiP – Microchip SAML21 Arm Cortex M0+ MCU @ 48 MHz, 32 KB RAM, 256 KB Flash, Semtech SX1276 LoRa Connectivity Frequency Range – 862 to 1020 MHz High level of accuracy and stability (32MHz TXCO) Max Tx Power: 20dBm; Max Sensitivity: -148dBm; Rx Current: 17mA (typical) Compliant with LoRaWan 1.0.2 Antenna – SMA and u.FL (IPEX) antenna connector I/Os – Feather headers with 20x IO pins including PWN, serial, I2C, SPI, 6x 12-bit ADC, 1x 10-bit DAC HW security – ATECC608A crypto authentication chip Programming and debugging 10-pin 4-pin […]
