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

OpenHarmony development board borrows BBC Micro:bit edge connector

OpenHarmony development board BBC micro bit

HopeRun’s HiHope development board features a HiSilicon Hi3861V100 32-bit RISC-V microcontroller compatible with OpenHarmony OS and looks very much like the BBC Micro:bit educational board notably with its edge connector. The board is also designed for youth education (in China) and comes with similar sensors, but there are some differences such as a 0.96-inch OLED instead of an LED matrix and support for offline voice recognition. There’s no wireless connectivity apart from NFC support. HiHope board specifications: MCU – HiSilicon Hi3861 32-bit microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory Display – 0.96-inch OLED display with 128×64 resolution (SSD1306) Connectivity – NFC with R/W mode, card emulation, and bidirectional mode USB – 1x USB Type-C port for power and programming Sensors – Temperature & humidity sensor, light sensor, microphone, 6-axis motion sensor Expansion – Edge connector with 5x rings (3x […]

HiPo batteryless NFC-powered 3.52-inch e-Paper display also comes with an SPI interface (Crowdfunding)

HiPo is a 3.52-inch black and white e-Paper Display that can be updated through NFC without the need for external power and offers an alternative to the 4.2-inch and 7.5-inch NFC-powered e-Paper displays from Wareshare that also operate without battery only using the data and power from NFC to update the image. Alternatively, Guangdong SID Technology’s HiPo display can also be connected to an SPI adapter board allowing the users to connect it to an STM32 board provided by the company, but it could also be used with Arduino boards, ESP8266 & ESP32 hardware platforms, Raspberry Pi SBCs and MCU boards, or any platform with an SPI interface.

Higole F7G Plus Review – An affordable rugged tablet tested with Ubuntu 20.04 & Windows 11

Ruggedized industrial-use PCs are typically expensive so it is refreshing to see Higole F7G Plus, an Intel Gemini Lake Refresh tablet, being offered at an affordable price. Higole kindly sent one for review and I’ve looked at functionality and performance running on Ubuntu and also its Windows performance. Hardware Overview The Higole F7G Plus is a 10.1 inch IPS touch screen rugged industrial fanless tablet that uses Intel’s 14 nm Gemini Lake Refresh N4120 processor which is a quad-core 4-thread 1.10 GHz Celeron processor boosting to 2.60 GHz with Intel’s UHD Graphics. Designwise, meeting the MIL-STD-810G standard which is the de facto ‘ruggedized’ standard for consumer products and covers whether the device can work in a broad range of environmental conditions including surviving dropping, is evidenced by the thick protective shell around the tablet. To ensure its IP67 Certification for waterproofing each of the ports are covered by detachable rubber […]
