NuCurrent showcases NFC charging at 3W, data rates up to 848 kb/s

The NFC Forum approved the Global Wireless Charging (WLC) specification last year with the new standard making it possible to wirelessly charge small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. The NFC WLC currently specifies power levels ranging from 100mW – 1W transmitted and data rates up to 106 kb/s, but NuCurrent claims to have gone beyond WLC specs, delivering over 3x more wireless power and over 8x faster data speeds. This was achieved with the company’s NuEva Development Platform for Near-Field Communication (NFC) Wireless Charging technology that provided up to 3W of power received (as opposed to just transmitted in the WLC specification) and data rates of up to 848 kb/s. NuCurrent expects the higher NFC charging power and data rates to enable new applications for small, space-constrained devices including wrist-wearables, smartwatches, styluses, […]

Upcoming events about RISC-V, RT-Thread IoT OS, and Embedded Linux

Three events about open/open-source technologies have been recently announced with namely the RT-Thread IoT OS Tech Conference, the jointly organized Open Source Summit and Embedded Linux Conference 2021, and the 2021 RISC-V Summit. Let’s have a quick look at what each will have to offer with the list in chronological order. RT-Thread IoT OS Global Tech Conference 2021 The first-ever RT-Thread IoT OS Global Tech Conference will take place online on September 16–17,2021, be free to attend, and feature talks about embedded technologies, new projects showcase, community contributors track mostly related to RT-Thread open-source real-time operating system, but also IoT development in general. The agenda has not been published just yet, as the call for speakers is still open until August 8th. People just wanting to attend can register through a Google Docs form. Somehow there’s no landing page on the main page, and instead, they’ve decided to publish information […]

Foscam SPC review – Part 2: Human detection, Android app, ONVIF support

In the first part of Foscam SPC WiFi spotlight camera review, we checked out the specifications, the package content, and some of the main components of the camera with SigmaStar SSC337DE processor and a Realtek RTL8822CS dual-band WiFi 5 module. I’ve now had time to play with the camera and tested it with the Foscam Android app, including human detection, and enabled ONVIF support to use the camera with compatible third-party apps or programs. Foscam SPC installation and setup with Android app Foscam SPC camera is designed to be wall-mounted, but for this review, I simply attached it to the branch of a small tree. Note that contrary to the other cameras I’ve tested, the camera angle can only be adjusted up and down or rotated, but there’s no direct left or right adjustment. I’ve also connected the power adapter to power up the camera, but I did not install […]
