SMLIGHT SLZB-06M Zigbee 3.0 PoE adapter gets Silabs EFR32MG21 microcontroller

SMLIGHT SLZB-06M

SMLIGHT SLZB-06M is a Zigbee 3.0 to Ethernet, PoE, USB, or WiFi adapter designed to work with multi-vendor software systems such as Zigbee2MQTT and Home Assistant ZHA. This will let you integrate any supported Zigbee devices into smart home automation systems like Home Assistant, OpenHub, or HomeSeer. The SLZB-06M is a variant of the SLZB-06 Zigbee PoE adapter introduced last year with the main difference being the Zigbee chip as the new model is equipped with Silicon Labs EFR32MG21 microcontroller instead of Texas Instruments СС2652Р. An ESP32 WiFi and BLE chip is still used to work with peripherals such as the LAN8720 Ethernet chip and a CP2102N USB/UART converter chip. SMLIGHT SLZB-06M specifications: Wireless SoCs Silicon Labs EFR32MG21 Arm Cortex-M33 microcontroller @ 80 MHz with 352KB flash, 1024KB ROM for protocols and library functions,  96KB SRAM, integrated power amplifier, Bluetooth 5.2 Low Energy and 802.15.4 radios (Zigbee and Thread) Espressif […]

Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.5 release

Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]

Orbbec Femto Bolt 3D depth and RGB USB-C camera supports Microsoft ToF technology

Orbbec Femto Bolt

Orbbec Femto Bolt is a 3D depth and RGB USB-C camera developed in collaboration with Microsoft and integrating the same ToF (Time-of-Flight) technology as found in the Microsoft Azure Kinect camera module and HoloLens 2 mixed reality head-mounted display. The new model follows the launch of the fully integrated Femto Mega featuring an NVIDIA Jetson Nano module introduced in January with the same ToF technology, so the new USB-C camera simply allows a wider selection of hosts. Orbbec has also launched the Femto Mega I variant with an IP65 metal enclosure. Orbbec Femto Bolt specifications: Cameras Depth camera 1 Mega Pixel ToF sensor 850nm wavelength 0.25 to 5.45m range depending on the depth mode Up to 1024×1024 @ 15 fps (WFoV) or 640×579 @ 30 fps (NFoV) FoV Wide – H: 120°; V: 120° Narrow – H: 75°; V: 65° RGB camera 4K resolution up to 3840×2160 @ 25 fps […]

RTL-SDR Blog V4 dongle launched with Rafeal R828D tuner chip

RTL-SDR Blog V4 dongle

RTL-SDR has just launched the RTL-SDR Blog V4 dongle for software-defined radio (SDR) enthusiasts based on the Rafael R828D tuner chip with three switchable inputs instead of the R860 chip used in RTL-DSR Blog V3 dongle. The new model still features the Realtek RTL2832U demodulator found in all previous versions of the SDR USB dongles but adds basic input filtering, integrates an improved LDO for the power circuity leading to fewer heat emissions, and improves HF reception thanks to a built-in upconverter. The main RTL-SDR Blog V4 dongle improvements include: Improved HF Reception thanks to a built-in upconverter instead of using a direct sampling circuit. Some positive consequences are that there’s no more Nyquist folding of signals around 14.4 MHz, improved sensitivity, and adjustable gain on HF. Improved filtering thanks to the three inputs of the R828D tuner chip found in the V4 dongle. Three bands (HF, VHF, and UHF) […]

ALFA Network HaLow-U – An 802.11ah WiFi HaLow USB adapter supporting AP and STA mode

WiFi HaLow USB adapter

ALFA Network HaLow-U is an 802.11ah WiFi HaLow USB adapter based on the Newracom NRC7292 chipset and NXP i.MX 6 processor that works both in access point (AP) and client (STA) modes. It delivers long-range WiFi up to one kilometer in the 900 MHz frequency ISM bands and is mostly useful for IP cameras and high-end sensors. The ecosystem around WiFi HaLow (802.11ah) is expanding slowly, but surely, and we previously covered a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras, and also ALFA Network’s AHPI7292S Raspberry Pi HAT that found its way into RAKWireless WisGate Connect gateway. The new HaLow-U USB adapter adds another way to bring WiFi HaLow connectivity to more devices. HaLow-U specifications: SoC – NXP i.MX6 Arm Cortex-A9 processor System Memory – 256MB DDR3 Storage – 32MB NOR flash Connectivity 802.11ah HaLow Newracom NRC7292 chipset […]

Coin cell-powered boards provide an easy way to test USB-C cables

C2C caberQU USB-C Cable Tester

The A2C caberQU and C2C caberQU boards enable the quick and easy testing of respectively USB-A to USB-C and USB-C to USB-C cables without external hardware. Powered by a CR2032 coin cell battery, the boards apply a voltage to all pins of a cable and measure which ones are connected to the other end. The results can be visualized immediately through various LEDS on the board. The C2C caberQU board comes with a dedicated LED for each of the 24 USB pins and the shield, and it’s possible to test the USB Type-C to USB Type-C cable in several different modes: USB 2.0/1.1 USB Power Delivery USB 3.0/3.1/3.2 Alternate Mode Debug Accessory Mode Audio Adapter Accessory Mode The A2C caberQU board has fewer pins and LEDS for testing USB-A to USB-C cables specifically, but it works the same way. Peter Traunmüller (aka petl) has shot a video showing one of […]

CrowView adds a 14-inch portable monitor to your laptop for $115 and up (Crowdfunding)

CrowView 14 inch laptop monitor extender

Elecrow CrowView is a lightweight 14-inch portable monitor designed to be attached to your laptop adding a secondary monitor to it through a clamping structure that works with laptops having a 13-inch to 16.5-inch display. We’ve seen this type of laptop monitor extension for years, and you’ll find various models on Amazon. But the Elecrow is now offering the CrowView at a significantly lower price than competitors especially if you pledge $114.90 for the super early bird reward on Kickstarter. The regular price ($179) can still be interesting as in this price range you’d usually get an 11-inch or 12-inch display. CrowView specifications: 14-inch IPS display with 1920×1080 resolution, 60 Hz refresh rate, 400 nit brightness Compatible with 13-inch to 16.5-inch laptops with 4 to 8mm thick displays thanks to a telescopic snap 230° hinge enabling face-to-face mode.
