Youyeetoo X1 x86 SBC Review – Part 2: GPIO, UART, I2C, SPI, NFC, PoE module, and power consumption

Youyeetoo X1 GPIO review

The Youyeetoo X1 x86 single board computer (SBC) with an Intel Celeron N5105 Jasper Lake CPU differs from a typical Intel or AMD mini PC by its range of IOs including SPI, I2C, UART, NFC connectivity, and support for PoE module that you won’t find in a typical computer, and that’s what we will test in the second part of the X1 SBC review along with power consumption. The Youyeetoo X1 SBC is also different from Arm-based single board computers since we can just install any x86-compatible operating system by ourselves, and w don’t need to flash a board-specific image like we would do with Arm SBCs and peripherals such as SPI, I2C or UART may be or may not usable immediately due to lack of supported drivers. We’ve already installed Ubuntu 22.04 on the Youyeetoo X1 in the first part of the review, so in the second part, we’ll […]

AirGradient ONE Kit Review – An open-source indoor air quality monitor

airgradient one ready to work

The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]

Review of RaZberry 7 Pro Z-Wave Raspberry Pi HAT and Z-Uno2 Z-Wave board

RaZBerry 7 Pro Z-Uno2 Z-Wave Review

Z-Wave.Me has sent us a couple of Smart Home devices based on Z-Wave technology for review, namely the RaZberry 7 Pro Raspberry Pi HAT and the Z-Uno2 board. The Swiss company has primarily developed Z-Wave products for years and is a member of the Z-Wave Alliance. For those who are concerned about the issues of signal interference in the 2.4GHz range (WiFi, Zigbee, Bluetooth, and Thread), Z-Wave technology is an excellent choice because it operates on a less congested frequency range of 800-900MHz and the technology has been around for more than 20 years, resulting in a wide variety of Z-Wave devices available in the market, and they can work well together across different brands due to a proper certification process which is another advantage when compared to other protocols. The two devices we received are RaZberry 7 Pro, which is a shield that plugs into the 40-pin GPIO header […]

SONOFF SNZB-06P Zigbee human presence sensor is based on a 5.8GHz microwave radar

SONOFF SNZB-06B human presence detection sensor

ITEAD has launched a new Zigbee sensor with the SONOFF SNZB-06P designed to detect human presence using a 5.8GHz microwave radar whose main advantage over a traditional PIR motion sensor is the ability to detect stationary persons since this type of sensor can detect breathing. You’ll need a Zigbee Hub from SONOFF such as the NSPanel Pro or SONOFF iHost, or from other manufacturers, for instance, the Amazon Echo Plus 2nd generation, or simply use a Zigbee USB dongle such as the SONOFF ZBDongle-E connected to a host like a Raspberry Pi. Configuration and control is done through the usual eWelink app for Android or iOS. SONOFF SNZB-06P specifications: MCU – Silicon Labs EFR32MG22 wireless microcontroller Human presence sensor 5.8GHz microwave radar Sensitivity configurable from 2.5 meters to 4 meters Wireless – Zigbee 3.0 (router type) up to 30 meters Misc – Red LED, magnetic base, button Power Supply – […]
