Murata LBWA0ZZ2HK/HL low-power Wi-Fi HaLow modules can communicate over 2km

Murata has recently introduced two new ultra-low power, sub-1 GHz Wi-Fi HaLow modules (LBWA0ZZ2HK and LBWA0ZZ2HL) compliant with Sub-1 GHz (S1G) 802.11ah Wi-Fi standard across key regions. The Type 2HK module operates at frequencies from 902MHz to 928MHz and features a communication range of 2km, whereas the low-power Type 2HL operates at 750MHz to 950MHz and can communicate over 1km. According to Murata, these modules can achieve high-speed communication over 1km and are suitable for applications such as smart devices, smart homes, smart accessories, and others. The modules are based on the NEWRACOM NRC7394 chipset built around an Arm Cortex-M3 with enough processing power for handling the Wi-Fi subsystem and user applications. Both modules feature an SPI host interface with peripherals including SPI, 2x UART, 2x I2C, 2-channel 10-bit ADC, and GPIO. Murata LBWA0ZZ2HK and LBWA0ZZ2HL specifications: HaLow SoC – Newracom NRC7394 SoC Frequency 2HL – Sub-1 GHz (750-950 MHz) […]

SONOFF CAM Slim Gen2 Review – A tiny indoor security camera tested with eWeLink and Home Assistant

We have received the latest tiny indoor security camera from SONOFF: the second generation of the CAM Slim series known as the CAM Slim Gen2 (or CAM S2 for shorts). Some of you might remember the first-generation CAM Slim model reviewed by Jean-Luc about two years ago. The Gen2 version keeps the same 1080p resolution but comes with several upgraded features, including AI algorithms to distinguish living beings, customizable detection zones, customizable privacy zones, sleep mode, enhanced low-light image quality, and flexible storage management. Although it’s packed with several enhancements, its price is lower than the Gen1. Let’s delve into the details! SONOFF CAM Slim Gen2 unboxing Inside the box, you’ll find a compact manual, a USB-C cable, a mounting kit, and a sticker template acting as a drilling guide. The camera is smaller than your palm and comes mounted on a versatile, rotatable base, making installation in various positions […]

u-blox SARA-R10001DE LTE Cat 1bis Module integrates an eSIM with Multi-IMSI and eUICC support

u-blox has introduced the SARA-R10001DE, an LTE Cat 1bis module with integrated eSIM featuring multi-IMSI technology and eUICC functionality. The module is pre-provisioned with Wireless Logic’s Conexa IoT Network SIM profiles for global IoT deployments. The eSIM supports OTA using Remote SIM Provisioning, allowing the module to switch between multiple stored SIM profiles to connect to the best available network. Multi-IMSI technology allows eSIMs to store multiple International Mobile Subscriber Identity (IMSI) profiles, enabling dynamic network switching for uninterrupted connectivity. eUICC functionality, based on the GSMA standard, facilitates OTA updates and profile management, simplifying operator switching and ensuring global compliance. Although SARA-R10001DE is u-blox’s first LTE Cat 1bis module with an embedded SIM (eSIM), we previously covered the u-blox LEXI-R10 LTE Cat 1bis module and associated evaluation kit, as well as Cavli C17QS Cat 1bis module built around the Qualcomm QCX217 microcontroller. u-blox SARA-R10001DE module specifications: LTE module – SARA-R10001DE […]

NetBSD 9.0 Released with Aarch64 Support, Arm ServerReady Compatibility

Yesterday, we wrote about Raspberry Pi 4 getting UEFI+ACPI firmware for Arm SSBR compliance allowing the board to run operating systems designed for “Arm ServerReady” servers out of the box. NetBSD 9.0 was just released on February 14, 2020, with support for Aarch64 (64-bit Arm) which had been in the works for a few years, and includes support for “Arm ServerReady” compliant machines (SBBR+SBSA). NetBSD 9.0 main changes related to hardware support: Support for AArch64 (64-bit Armv8-A) machines Compatibility with “Arm ServerReady” compliant machines (SBBR+SBSA) using ACPI. Tested on Amazon Graviton and Graviton2 (including bare metal instances), AMD Opteron A1100, Ampere eMAG 8180, Cavium ThunderX, Marvell ARMADA 8040, QEMU w/ Tianocore EDK2 Symmetric and asymmetrical multiprocessing support (big.LITTLE) Support for running 32-bit binaries via COMPAT_NETBSD32 on CPUs that support it Single GENERIC64 kernel supports ACPI and device tree based booting Supported SoCs Allwinner A64, H5, H6 Amlogic S905, S805X, S905D, […]

A Day at Chiang Mai Maker Party 4.0

The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer […]

Getting Started with OpenCV for Tegra on NVIDIA Tegra K1, CPU vs GPU Computer Vision Comparison

This is a guest post by Leonardo Graboski Veiga, Field Application Engineer, Toradex Brasil Introduction Computer vision (CV) is everywhere – from cars to surveillance and production lines, the need for efficient, low power consumption yet powerful embedded systems is nowadays one of the bleeding edge scenarios of technology development. Since this is a very computationally intensive task, running computer vision algorithms in an embedded system CPU might not be enough for some applications. Developers and scientists have noticed that the use of dedicated hardware, such as co-processors and GPUs – the latter traditionally employed for graphics rendering – can greatly improve CV algorithms performance. In the embedded scenario, things usually are not as simple as they look. Embedded GPUs tend to be different from desktop GPUs, thus requiring many workarounds to get extra performance from them. A good example of a drawback from embedded GPUs is that they are […]
