$119 MoreSense MS-06 air quality monitor features a Sensirion SCD40 sensor and an ESP32-S3 MCU

The MoreSense MS-06 is an ESP32-S3-based air quality monitor that takes CO², temperature, and humidity readings through a Sensirion SCD40 sensor which offers reliable performance and a lifespan of more than ten years. The MS-06 monitor’s results are identical to the Aranet4’s (considered best-in-class), putting it in a pretty good spot accuracy-wise. It is the latest entry in the MoreSense line of air quality monitors and comes with a more compact design and a touchscreen display. The built-in web server runs an interface that displays measurements, historical data visualizations, setup options, and firmware updates. Operation is completely local; sensor data can be stored on the device or a microSD card. The MoreSense MS-06 air quality sensor can be used to control a ventilation system, contributing to significant energy savings. This can be achieved through your home automation system or by using a smart plug. MoreSense MS-06 specifications: Microcontroller – ESP32-S3 […]

XIAO RP2350 is a tiny USB-C board based on Raspberry Pi RP2350 MCU

The XIAO RP2350 is an upgrade to Seeed Studio’s XIAO RP2040 board with a more powerful Raspberry Pi RP2350 dual-core Cortex-M33 or dual-core RISC-V microcontroller found in the just-launched Raspberry Pi Pico 2 board. The new Raspberry Pi RP2350 USB-C board has the same form factor but adds eight more GPIOs on the bottom with pads for a total of 19 GPIOs, and we lose two LEDs for serial port connectivity. Most people will still be fine with the XIAO RP2040, but if you need a more powerful microcontroller, extra memory, a few extra GPIOs, and built-in security, then the XIAO RP2350 will be an improvement. XIAO RP2350 specifications: Microcontroller – Raspberry Pi RP2350 MCU CPU – Dual-core Arm Cortex-M33 processor @ 150MHz (Note: again RISC-V is not mentioned at all by Seeed Studio, like for the Cytron MOTION 2350 Pro board) Memory – 520KB internal RAM 8KB OTP Storage […]

Waveshare UPS HAT (E) for Raspberry Pi 5/4/3B+ takes four 21700 Lithium batteries, supports USB PD 3.0

The Waveshare UPS HAT (E) is a UPS expansion board for Raspberry Pi 5/4B/3B+ that supports four 21700 Lithium batteries and includes a battery fuel gauge IC for monitoring voltage, current, and capacity. The USB Type-C port is compliant with the PD 3.0 standard and allows for 40W fast bi-directional charging, and a high-power buck chip provides a 5V/6A output. Additionally, it supports I2C for real-time status updates. Previously, we wrote about the wider SupTronics Raspberry Pi 5 UPS HAT, which supports four 18650 batteries and delivers up to 5V with a higher current output of 5A. This HAT has no Type-C support and uses a DC jack and XH2.54 connector for 6V-18V input. Feel free to check it out if you’re interested in this product. Waveshare UPS HAT (E) specifications: Compatibility – Raspberry Pi 5 / 4B / 3B+ USB Interfaces USB Type-C Input/Output – Supports multiple voltage levels […]

LILYGO T-Halow is an ESP32-S3 board with long-range WiFi HaLow, OV2640/OV5640 camera support

LILYGO T-Halow is an ESP32-S3 board equipped with a WiFi HaLow module with up to 1.2km range, a connector compatible with OV2640 and OV5640 camera modules, and an 18650 battery holder for power, as well as several GPIOs for expansion. We first wrote about 802.11ah low-power long-range WiFi standard operating at 900 MHz in 2014, but adoption has been slow and we’ve seen a few 802.11ah (WiFi HaLow) chips from Newracom and Morse Micro over the years, as well as USB adapters, a Raspberry Pi HAT, a mini PCIe card, gateways, and some development boards. All those rely on a Linux host, but the LILYGO T-Halow features a TX-AH WiFI HaLow module from Taixin Semiconductor that’s controller by AT commands through an ESP32-S3 or a micro USB port. LILYGO T-Halow specifications: Wireless modules ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 […]
