STMicro ST25DA-C is the first NFC chip with Matter support

ST ST25DA-C is an NFC chip with built-in support for the latest Matter 1.5 protocol, enabling easier installation of smart devices on home networks, including lighting, access control, security cameras, or any IoT device. NFC here is used as an alternative to Bluetooth LE or QR core commissioning. NFC tap-to-pair functionality enables users to tap an NFC tag code on a device with their smartphone to securely and easily add it to their Matter-compatible app(s) and network(s). Besides batteryless commissioning, the ST25DA-C chip can also be used for firmware updates over I2C (Matter OTA), and secure storage for keys & certificates. ST25DA-C secure NFC tag specifications: Contact interface 1.62 V to 3.3 V supply voltage range ESD protection Human body model (HBM): 6 kV for digital and antenna pads Charge device model (CDM): 1 kV based on a STMicroelectronics module I2C serial interface up to 400 kHz Contactless interface Power […]

Avalue VNS-10WAD – A 10.1-inch slim, fanless Intel N50 touch panel PC with antibacterial housing

VNS 10WAD 10.1 Inch Ultra Slim Panel PC angle view

Avalue VNS-10WAD is a 10.1-inch, 1280×800 slim fanless touch panel PC powered by an Intel N50 CPU, which looks very similar to the BCM OFT10W-ADLN panel PCs. Both feature the same dual-core Alder Lake-N processor and a 10.1-inch touchscreen display, but the new VNS-10WAD comes with an antibacterial housing instead of an open-frame design, NFC support, and a 2MP camera. It also features 8GB LPDDR5 RAM and 64GB eMMC storage. Connectivity options include Wi-Fi 6, optional Bluetooth 5.2, Gigabit Ethernet, USB 3.0, and RS232/RS422/RS485. The device has an operating temperature range of 0–40°C, supports 12–24V DC input, and comes with PoE+ (802.3at) support for power over Ethernet. Avalue VNS-10WAD specifications: SoC – Intel Processor N50 dual-core processor up to 3.4 GHz with 6MB cache, 16EU Intel UHD Graphics; TDP: 6W System Memory – Up to 8GB LPDDR5 onboard Storage 64GB eMMC onboard MicroSD card slot Display 10.1-inch LCD, 1280×800 resolution, LED backlight, […]

NFC Release 15 quadruples the range to 2cm for faster, more reliable contactless interactions

The NFC Forum has just announced NFC Release 15 that quadruples NFC range from 0.5cm to 2cm and enables faster, more reliable contactless interactions for wireless charging, kitchen appliances, wearables, and digital keys. The extended NFC range, also known as the operating volume, may make some people laugh since it’s only 2 cm we are talking about, but it has practical applications, as NFC contactless interactions will start sooner and require less precise device alignment. The NFC Release 15 also focuses on the NFC Digital Product Passport Standard to provide a data-agnostic framework allowing a single NFC tag to store and transmit both standard and extended DPP data using common NFC Data Exchange Format (NDEF) records. I wish I could explain how the extended NFC range and DPP standard are implemented in the new release, but I can’t because the technical specifications are only available for download to NFC Forum […]

Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

7.5inch NFC Powered e Paper V2 side view

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock.
