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 […]

Seguro 150 Bluetooth and NFC temperature logger works without mobile app (for the receiver)

Bluetooth NFC Temperature Logger

Sensified.io Seguro 150 is a 4mm thick waterproof temperature logger designed for cold chain shipping applications in the food and healthcare industries and can also be used in retail settings. Most IoT devices require you to install some type of proprietary app, but the Seguro 150 is said not to require any app for the receiver and the temperature logger instead relies on Bluetooth LE and NFC so he/she can tap his/her phone to access the data and it’s also possible to receive PDF or Excel reports by email. Seguro 150 specifications: Wireless Bluetooth LE 5.0 up to 2Mbps Near-field communications (NFC) up to 10mm range Protocol – Type 4 Tag Emulation Temperature measurement Temperature Range – -30°C to +40°C Thresholds – High, Low Measurement Response – Sampling Interval, Start Delay Buffer – 7 days with 2-minute sampling to 7 months with 60-minute sampling Misc – Multi-color LED Battery – […]

Flipper Zero hardware & wireless hacking tool gets an app “store” with open-source app

Flipper Zero

Flipper Zero portable multi-tool for pentesters and hardware hackers has now gotten an app “store” with currently around 100 free and open-source apps available through the device’s Android or iOS app. I missed it at the time, but the Flipper Zero launched on Kickstarter in July 2020 and was massively popular with close to 5 million dollars raised from almost 38,000 backers. The tool looks like a toy but it allows hacking with GPIOs and short-range wireless protocols such as Bluetooth, RFID, NFC, and infrared. Flipper Zero specifications: Wireless MCU  – STMicro STM32WB55RG with Arm Cortex-M4 application core @ 64 MHz, Arm Cortex-M0+ network core @ 32 MHz, 1024 KB flash, 256KB SRAM Storage – MicroSD card slot up to 64GB Display – 1.4-inch monochrome LCD (black on orange background) with 128×64 resolution via ST7565R SPI display controller Connectivity Bluetooth 5 LE & 802.15.4 via STM32WB55 microcontroller Bluetooth LE – […]

The Wi-R protocol relies on body for data communication, consumes up to 100x less than Bluetooth

Wi-R vs Bluetooth

The Wi-R protocol is a non-radiative near-field communication technology that uses Electro-Quasistatic (EQS) fields for communication enabling the body to be used as a conductor and that consumes up to 100x less energy per bit compared to Bluetooth. In a sense, Wi-R combines wireless and wired communication. Wi-R itself only has a wireless range of 5 to 10cm, but since it also uses the body to which the Wi-R device is attached, the range on the conductor is up to 5 meters. While traditional wireless solutions like Bluetooth create a 5 to 10-meter field around a person, the Wi-R protocol creates a body area network (BAN) that could be used to connect a smartphone to a pacemaker, smartwatch, and/or headphones with higher security/privacy and longer battery life.   One of the first Wi-R chips is Ixana YR11 with up to 1Mbps data rate, and they are working on a YR21 […]
