$5 Sinilink WiFI USB Power Switch Works with Tasmota Firmware, Supports up to 20V/5A

Late last year, ITEAD launched Sonoff Micro WiFi USB switch that allows you to turn on and off USB powered devices over WiFi using eWelink app for Android or iOS. It integrates with Amazon Alexas and Google Home, and does the job, but people who like to use the open-source Tasmota firmware will be disappointed to learn it’s not based on ESP8266 processor hence not compatible. Luckily, there’s another option: Sinilink WiFi USB switch (aka XY-WFUSB) based on ESP8266 WiFi SoC, and supporting up to 20V/5A according to the manufacturer. It is currently sold for under $5 including shipping on Aliexpress. Sinilink XY-WFUSB specifications: WiSoC – Espressif ESP8266 processor with 802.11b/g/n WiFi 4 USB Input – USB type-A female port supporting 3.5V to 20V up to 5A (100 Watts max) USB Output – USB type-A male port up to 100W Misc On/off button – Pressing 5 seconds also change the […]

Yeelight Smart LED Bulb 1S (Color) Review with Android App and Google (Local) Home

Yeelight Smart LED Bulb Google Local Home

Last summer, Google released the Local Home SDK developer preview which allows developers to run actions and use resources on the local device rather than in the Cloud for lower latency. One company that updated its devices is Yeelight whose WiFi smart lights have now been enhanced with the Google Local Home SDK helping deliver a latency of less than 0.3 seconds, so you don’t need to wait after your voice command has been processed by Google Assistant. The company contacted me to test the new feature and had GearBest sent a sample of Yeelight Smart LED Bulb 1S (Color) for review. I have never tested Yeelight devices so I’ll start with an unboxing, testing with the Android app, before trying it out with Google Home and Google Assistant. Unboxing of Yeelight Smart LED Bulb 1S (Color) The package has some useful information about the light bulb including some specifications […]

Realtek RTL8720DN Dual-Band WiFi & Bluetooth 5.0 IoT Modules Sell for $4 and Up

BW16 RTL8720DN Dual-band WiFi & Bluetooth Module

There are plenty of 2.4 GHz WiFi modules for IoT project based on processors ranging from Espressif Systems ESP8266 to TI CC3200, or Realtek RTL8710. Some others add Bluetooth 4.2/5.0 such as Espressif Systems ESP32, but it’s much harder to find solutions with dual-band WiFi especially if you have a tight budget for your project or product. But Realtek RTL8720DN – part of AmebaD family – offers just that with the Arm Cortex-M4/M0 wireless MCU supporting dual-band (2.4/5.0GHz) 802.11 b/g/n WiFi and Bluetooth 5.0 connectivity, and found in modules currently selling for as low as $3.90 or 24 RMB in single units. B&T BW16 RTL8720DN Module Specifications: Wireless SoC – Realtek RTL8720DN MCU with KM4 Arm Cortex-M4 core @ 200 MHz and KM0 Arm Cortex-M0 core @ 20 MHz Connectivity WiFi 802.11 a/b/g/n WiFi 4 Frequency Range – 2.412-2.484GHz & 5.180-5.825GHz Data Rates 802.11a: 6,9,12,18,24,36,48,54Mbps 802.11b: 1,2,5.5,11Mbps 802.11g: 6,9,12,18,24,36,48,54Mbps 802.11n: […]

OpenWrt 19.07 Released with WPA3 Security, a Faster LuCI web interface

OpenWrt is a popular Linux operating system targeting embedded devices, usually routers (but not only), and serves as a complete replacement for the vendor-supplied firmware on supported devices. The developers released OpenWrt 19.07 on January 6, to succeed OpenWrt 18.06 the previous stable release. The new version brings various improvements including WPA3 support, client-side rendering of the LuCI web interface for faster rendering or a lower-load on the router, and introduces the ath79 target for MIPS routers with device tree support. While WPA3 WiFi security is part of OpenWrt 19.07, it is not enabled by default because the necessary packages hostapd-openssl (access point), wpa-supplicant-openssl (station support only) and wpad-openssl (AP + station) take a fair amount of space, and won’t fit on devices with 8MB flash or less. Another reason for not enabling WPA3 is that many existing client devices will never support WPA3, and some client devices that support […]

WiFI 6E Aims to Leverage 6 GHz Unlicensed Spectrum

If you live and/or work in an urban environment, you may have noticed 2.4GHz WiFi may not be so reliable as too many people are using the frequency leading to interference. 5 GHz WiFi is here to help, but with the Internet of Things more and more WiFi devices will come online in the next few years, and there won’t be enough capacity using 2.4 and 5 GHz. 60GHz WiFi (802.11ad/802.11ay) may not work for IoT since the signal would not go through walls. That’s why the Wi-Fi Alliance has introduced WiFi 6E, and upgrade of WiFi 6, that can leverage 6 GHz unlicensed spectrum and expand the bandwidth available for Wi-Fi. I’ve taken the US spectrum wall chart from 2016 to show where WiFi 6E would stand, and it looks pretty crowded to me with mobile, fixed and satellite applications using the 5.925 to 7.125 GHz spectrum to be […]
