UL-Certified TP-Link Kasa Smart Plug with Dual Outlet Sells for $19.99 (Promo)

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 […]

3µA/MHz Ambiq Apollo 4 MCU Targets Battery-powered IoT Devices with Voice Processing

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 […]
