Matter 1.4 specification improves multi-admin and energy management, adds new devices like solar panels, batteries, and water heaters

We covered the Matter 1.3 specification in May 2024, but the Connectivity Standards Alliance is wasting no time and the Matter 1.4 specification is already out with features and improvements such as “Enhanced Multi-Admin”, Matter certifiable Home Routers and Access Points, energy management enhancements, and several new device types such as solar power equipment and batteries. Matter has been deployed in millions of Smart Home products in just a few years and aims to enable interoperability between devices from multiple vendors. Paisit reviewed a few Matter products from SONOFF including the MINIR4M Smart Switch, SONOFF Zigbee Bridge Ultra, and SwitchMan M5 Matter wall switch, and while Matter interoperability is working since devices can be controlled from Matter-compatible apps (e.g. Apple Home), users do lose some features found in the “native” app such as eWelink in the case of SONOFF devices. Matter 1.4 key improvements and new features: Home Routers and […]

Wi-Fi 8 (802.11bn) to focus on reliability and efficiency while maintaining Wi-Fi 7 performance

WiFi 4 vs WiFi 5 vs WiFi 6 vs WiFi 7 vs WiFi 8

Wi-Fi 7 (802.11be) routers and modules have only been launched recently, but engineers are already working on Wi-Fi 8 (802.11bn) “Ultra High Reliability (UHR)”, and MediaTek shared some details in a whitepaper detailing some of the improvements of the new standard for its upcoming Filogic Wi-Fi 8 SoCs. Surprisingly, there aren’t any enhancements to the maximum performance with Wi-Fi 8 still offering up to 320 MHz channel bandwidth, 23 Gbps maximum PHY rate, and support for 2.4 GHz, 5GHz, and 6GHz frequency bands, as well as up to 8 spatial streams. The Wi-Fi 8 improvements are all meant to improve Wi-Fi reliability, network efficiency, and power consumption in IoT use cases, which will end up improving the overall WLAN performance when many nodes are connected. Wi-Fi 8 new features: Coordinated Target Wait Time (TWT) allows low-power IoT devices to negotiate specific times for transmission with access points in order to […]

$20 ATOMIC Display Base is a low-cost HDMI display driver for M5Stack’s ESP32-based Atom IoT controllers

M5Stack has recently launched the M5Stack ATOMIC Display Base, an HDMI display driver designed to emulate traditional SPI TFT-LCD data output using Gowin GW1NR-9C FPGA and a built-in LT8618SX RGB-to-HDMI chip and designed to work with the company’s Atom IoT controller family based on ESP32 wireless microcontrollers. The module supports up to 720p (1280×720) image output with a 24-bit color depth and has an average frame rate of 12–16 FPS. Additionally, it can be paired with ATOM series hosts for various memory and application needs. These features make this compact device suitable for industrial control displays, smart home information screens, educational and conference presentations, and remote monitoring displays. The only downside of this device is that it requires a display with adaptive resolution scaling to avoid compatibility issues.

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 […]

ORICO COM2-T3 review – A 40Gbps SSD enclosure tested with a 7000MB/s M.2 NVMe SSD

ORICO COM2-T3 40Gbps SSD enclosure review

ORICO sent me a COM2-T3 SSD enclosure capable of 40 Gbps speeds for review along with the company’s 1TB O7000 NVMe SSD rated at up to 7000MB/s read speed which converts to about 56 Gbps and should be plenty enough to test 40 Gbps SSD enclosure. Thunderbolt 4 and USB4 are not always equivalent But before going into the review itself, here’s some background information. When I test the USB-A and USB-C ports in mini PC reviews, I rely on an ORICO M234C3-U4 NVMe SSD enclosure with an Apacer SSD. That enclosure was falsely advertised as a “USB4″ enclosure but still works at 40Gbps with an Intel JH7440 Thunderbolt 3 chip that works with 40 Gbps USB Type-C ports and a JMS583 “USB 3.1 Gen 2 to PCIe NVMe Gen3” bridge for USB 3.0 ports up to 10 Gbps. I always assumed a 40Gbps USB-C peripheral would always work with […]

Boardcon Compact3588S SBC – A Raspberry Pi 5 alternative based on Rockchip RK3588S AI SoC with M.2 socket for SSD or 4G LTE module

Boardcon Compact3588S SBC Raspberry Pi 5 Alternative

Boardcon Compact3588S SBC is another Raspberry Pi 5 alternative powered by a Rockchip RK3588S octa-core Cortex-A76/A55 SoC with a 6 TOP NPU for AI acceleration, up to 16GB RAM, up to 256GB eMMC flash, and all the features found in the Raspberry Pi 4, plus an M.2 socket supporting either an NVMe SSD or a 4G LTE module in conjunction with a Nano SIM card slot. It more closely follows the Raspberry Pi 4 form factor, but Rockchip RK3588S’ performance and capabilities make it a direct Raspberry Pi 5 competitor. Contrary to most credit card-sized single board computers, it follows a carrier board + soldered-on system-on-module design, rather than a single PCB. Boardcon Compact3588S specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz GPU – Arm Mali-G610 GPU with OpenGL ES 3.2, OpenCL […]
