$35 SONOFF POW ring smart power meter (POWCT) safely supports up to 100A

SONOFF POW Ring smart power meter

SONOFF POW Ring smart power meter is the first CT clamp-based WiFi power meter from ITEAD. It is designed for installation in an electric cabinet to measure whole-house power consumption with up to 100A current. The power meter relies on an ESP32 microcontroller for control and wireless connectivity with a range of up to 130 meters thanks to an external high-gain antenna. It is supported by the usual eWelink mobile app that also enables integration with Google Home, Amazon Alexa, and IFTTT services, and ITEAD also mentions integration with the Home Assistant open-source framework.

The Lark Weather Station works with Arduino, ESP32, micro:bit, Raspberry Pi, and other boards

Lark Weather Station Arduino ESP32 Raspberry Pi

The Lark Weather Station measures wind speed, wind direction, temperature, humidity, and air pressure through a range of sensors and connects to popular development boards such as Arduino UNO, ESP32, BBC micro:bit, Raspberry Pi, or DFRobot Unihiker through I2C or UART. We’ve seen several projects for Internet-connection weather stations that retrieve weather data from the web and display the results locally, but the Lark Weather Station allows the users to get atmospheric data right in his/her current location thanks to its built-in anemometer, wind vane, and built-in sensors, as well as expansion interfaces for additional sensors. Lark Weather Station specifications: Storage – 16MB flash good to store about 160 days of data (when data is recorded once per minute) Sensors Compass Anemometer Wind Speed: 0.5~12m/s Cover to protect the anemometer during storage/transport Wind vane and wind direction shaft to report the wind direction (eight directions) Temperature Range –20~60℃ ±0.2℃ Humidity […]

Arducam KingKong – A Raspberry Pi CM4-based Edge AI camera with global shutter sensor, Myriad X AI accelerator

Arducam KingKong

ArduCam KingKong is a Smart Edge AI camera based on the Raspberry Pi CM4 and system-on-module based on Intel Myriad X AI accelerator that follows the Raspberry Pi 5-powered Arducam PiINSIGHT camera introduced at the beginning of the year. The new product launch aims to provide a complete Raspberry Pi-based camera rather than an accessory for the Raspberry Pi 4/5. Smart cameras built around the Raspberry Pi CM4 are not new as we previously covered the EDATEC ED-AIC2020 IP67-rated industrial AI Edge camera and the StereoPi v2 stereoscopic camera used to create 3D video and 3D depth maps. The ArduCam KingKong adds another option suitable for computer vision applications with an AR0234 global shutter module, PoE support, and a CNC metal enclosure. ArduCam KingKong specifications: SoM – Raspberry Pi Compute Module 4 (CM4) by default CM4104000 Wireless 4GB RAM Lite (0GB eMMC). AI accelerator – Luxonis OAK SOM BW1099 based on Intel […]

600 MHz STM32H7R/S Cortex-M7 MCUs feature 620KB SRAM, 64KB boot flash, optional NeoChrom GPU

STMicro STM32H7RS

STMicro has launched the high-performance 600 MHz STM32H7R/S Arm Cortex-M7 microcontrollers: the STM32H7R3/S3 General-purpose MCU lines, and STM32H7R7/S7 graphics MCU lines adding a NeoChrom 2.5D GPU. Both ship with a large 620KB SRAM and a small 64KB boot flash. The reason for the small boot flash is to have the application code and data stored off-chip memory ICs to provide more flexibility to customers when it comes to the choice of memory type and capacity to fulfill the application requirements and lower the BoM cost. The “S” in the STM32H7S microcontrollers stands for Security with a crypto/hash engine that can help the final product achieve SESIP Level 3 and/or PSA Certified Level 3 certifications. Many of the specifications are similar to the STM32H7 microcontrollers, but performance is better going slightly faster than the 550MHz STM32H7 MCUs added in 2020, and the STM32H7R/S adds some new features: 200 MHz Hexadeca SPI […]

Banana Pi launches $30 WiFi 6 router with Triductor TR6560 SoC running a fork of OpenWrt

Banana Pi BPI-Wifi 6 Router

When Banana Pi started to sell the low-cost Banana Pi BPI-WiFi 6 router board powered by Triductor TR6560 dual-core SoC and TR5220 WiFi 6 chipset, I mentioned they should probably offer a complete system with enclosure and antennas for this to become more popular. It took a while, or about nine months to be precise, but the Banana Pi BPI-WiFi 6 router is now available with a plastic enclosure, four external antennas, an Ethernet cable, and a power supply for $30.90 plus shipping on Aliexpress.
