Singles Day 2020 is now behind us, but just like every year, international Black Friday and Cyber Monday deals and coupons are coming, and even already launched over one week before the actual events. And CNX Software will link to promotions from Chinese online websites that offer such deals with Aliexpress, Banggood, GearBest, GeekBuying, and others. Aliexpress Black Friday Fest will start on November 23, 12:00 AM PT, and last till November 27, 11:59 PM PT with up to 70% discounts. But you can also browse the website to find discounts, and add products to your cart before ordering during the event. There will also be $20 and $40 coupons for orders over $40 and $100 respectively, but conditions are unclear at this time. Banggood’s Crazy Friday event takes place during an even longer period between November 2nd and December 6th. There are special sitewide coupons for PayPal payments with $7 off for $70+ orders, and $12 off for $110+ […]
[Update: The information from Shelly about a new “Cortana M3” processor is incorrect, we’ve been contacted by Silicon Labs, and there’s no Cortana M3 microcontroller from the company, Shelly is just using one of the company’s Cortex-M3 based WiFi solutions (SoC or module). The article remains unchanged] WiFi is one of the most convenient ways to connect IoT devices as it’s omnipresent, low-cost, and the range is ideal for the typical smart home. That’s all good until you start to power the device with a tiny battery, as WiFi consumes much more power than Zigbee, Z-Wave, or Bluetooth. Over five years ago, Rockchip RKi6000 WiFi SoC promised Bluetooth 4.0 LE power consumption numbers allowing coin-cell powered WiFi devices, and there were some demos the following year, but I’ve yet to see a consumer device based on the solution. This brings me to the main topic of this post: Shelly Motion, a soon-to-be-launched smart motion sensor said to be powered by […]
Last December, we reported that Amazon, Apple, Google, and the Zigbee Alliance had partnered to create Project Connected Home over IP (CHIP) working group with the goal of developing a royalty-free, secure Smart Home standard to increase compatibility among products over WiFi, Ethernet, Bluetooth LE, Cellular, 802.15.4 and others community protocol. Infineon has now unveiled OPTIGA Trust-M evaluation kit for Raspberry Pi designed to experiment with Connect Home over IP standard and comprised of Infineon Shield2Go HAT/adapter board, and OPTIGA Trust-M Security Shield2Go board equipped with Infineon OPTIGA Trust-M “Common Criteria Certified EAL6+” security controller. The Shield2Go adapter just re-routes the 40-pin Raspberry Pi header I/Os to sockets compatible with Infineon boards and a prototyping area. So the most important part is OPTIGA Trust-M Shield2Go which supports the following: X.509 certificates Device authentication Cryptographic support ECC NIST curves up to P-521, Brainpool r1 curve up to 512 RSA up to 2048 AES key up to 256, HMAC up to SHA512, […]
Arduino is well-known for its maker boards and shields that are sometimes sold as part of kits to experiment with electronics. Arduino Oplà IoT kit is a little different as it looks more like an actual consumer product once assembled. Powered by an Arduino MKR WiFi 1010 board, it is designed to make getting started with IoT easy for beginners, while still allowing more advanced users to customize and hack their smart home applications. Arduino Oplà IoT Kit is comprised of several hardware components: MKR IoT carrier with a 1.2-inch OLED color display, onboard environmental sensors (temperature, humidity, pressure, light, and proximity), IMU sensor, Grove connectors, two 24V relays, and five capacitive touch buttons. Arduino MKR WiFi 1010 board powered by Microchip SAMD21 Cortex-M0+ MCU and equipped with a 2.4 GHz WiFi 4 and Bluetooth 4.2 module based on ESP32 chip. Sensors – PIR motion sensor and moisture sensor A circular plastic enclosure Various cables No soldering is required with […]

WiFi smart sockets to control home appliances have been around for a few years, and one of my favorite companies is Sonoff as they offer a variety of affordable smart plugs pre-loaded with eWelink firmware and compatible with open-source firmware like Tasmota and ESPurna. The company is also attentive to safety. communicate issues with customers, and recently wrote a post entitled “Safety is our responsibility” where they detail all steps taken to make sure their mains connected device sare safe to use. Sadly that does not include safety certifications like UL/ETL, or TUV which may have implications for your home insurance depending on where you live, and for peace of mind, it’s always good to have a third verify your design for safety. Which brings me to the main point of this point, as a UL-certified dual-outlet smart socket, namely TP-Link Kasa Smart Plug, is currently on sale for $19.99 when ticking for the $10 discount coupon. [Update: They also […]
Ambiq Micro is using sub-threshold voltages under 0.5V to offer ultra-low-power Arm microcontrollers. In 2015, the company launch the Apollo Cortex-M4F MCU with 30µA/MHz power consumption in active mode, which was followed in 2016 by Apollo 2 in consuming just 10µA/MHz, and Apollo 3 (Blue) dropped power consumption to as low as 6µA/MHz against using a Cortex-M4F @ 48 MHz in active mode. The fourth generation of ultra-low-power Apollo microcontroller has now been announced with Apollo 4 and Apollo 4 Blue microcontrollers – the latter adding Bluetooth – halving the power consumption of Apollo 3 at just 3µA/MHz, or ten times less than the original ultra-low-power MCU from the company. Apollo 4 (Blue) specifications and key features: MCU Core – Arm Cortex-M4F core up to 192 MHz (TurboSPOT) with FPU, Memory Protection Unit (MPU), and Secure Boot GPU – 2D/2.5D graphics accelerator with full alpha blending, texture and frame buffer compression Ultra-Low Power Memory Up to 2MB of non-volatile MRAM […]
The new Z-Wave Alliance Technical and Certifications workgroup, part of the Z-Wave Alliance, has announced the new Z-Wave Long Range (Z-Wave LR) specifications offering up to four times the range, support for ten times larger network, and 10-year coin cell battery life while keeping backward compatibility and interoperability Z-Wave LR will support up to 2000 nodes on a single smart home network making it suitable for indoor and outdoor smart home applications in multi-dwelling units, hotels, and hospitals, and removing the need for repeaters. The Z-Wave LR specification will be managed and certified under the Z-Wave Plus V2 certification program that currently mandates the inclusion of the enhanced S2 security framework as well as SmartStart plug-and-play setup feature for the consumer smart home. More details may be found on the press release and some of the sessions that were presented at Works With by Silicon Labs Virtual Conference on September 9-10, 2020.
