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 ATOMIC Display Base (GW1NR)

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

SARA-R10001DE top and bottom

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 […]

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

ESP32-based YULC USB-C LED Controller features dual power inputs, supports WLED and ESPHome firmware

YULC complete assembly

The YULC (Yes, a USB-C LED Controller) board is a compact, ESP32-S3-powered LED controller with USB-C and DC jack power inputs. It is a fully featured board that can easily replace a rat’s nest of wires and save space and time. This ESP32 LED controller features a built-in buck regulator that converts input power from the USB-C port or barrel jack to the voltage needed for the LED strips. The YULC provides two separate LED channels with a level shifter each to ensure clean and powerful data output, removing the need for a sacrificial pixel or external level shifter. Each channel also has a power MOSFET that can turn off the channels individually and dim simple LED strips via PWM. AAElectronics, the maker, has previously released an IR remote—the Home Assistant-compatible ESP 360 Remote—which we covered at the time. Similar products include the SMLIGHT A1-SLWF-03, DFRobot’s EDGE102-DMX512, and the PixelBlaze […]
