Xiaomi has introduced several inexpensive home automation products over the years, often under their Mijia brands with for example a WiFi to IR blaster, a Zigbee & WiFi smart home kit, a smart door lock, or a smart speaker among other products. Recently, the company has launched the Xiaomi Smart Multi-mode Gateway that supports Zigbee 3.0, WiFi, Bluetooth, and Bluetooth Mesh. Xiaomi Mijia Smart Multi-mode Gateway (model ZNDMWG03LM) key features and specifications: Connectivity ZigBee2.0 / ZigBee3.0 2.4GHz Wi-Fi 2×2 MIMO Bluetooth & Bluetooth Mesh Compatible with Apple Homekit Max range – 200 meters (Line-of-Sight) Up to 32 devices Power Supply – 5V/1A Dimensions – 90x25mm Temperature Range – -5℃-50℃ Humidity – 0%-95%RH, non-condensing The gateway can be controlled via Mi Home app running on Android 5.0 or iOS 12.0 smartphones. It’s compatible with Apple Homekit, Xiaomi Mi AI speaker, and the earlier Zigbee/WiFi kit with Aqara gateway and Zigbee sensors […]
Polos GD32V Alef is a Tiny RISC-V MCU Board Selling for $3
We first found out about GigaDevice GD32V 32-bit RISC-V MCU last summer, as an update/alternative to the earlier STM32 compatible GD32 Arm Cortex-M3 microcontroller from the company with higher performance and lower power consumption, while keeping the price identical. The first low-cost GD32V development board we covered was Longan Nano going for $5 with an OLED display and an acrylic case. If you don’t need either or want to access all pins from the 48-pin MCU, you can now order an even cheaper GD32V RISC-V MCU board with Polos GD32V Alef going for $2.99 on Analoglamb website. Polos GD32V Alef board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM USB – 1x micro USB OTG port for power and programming Expansion – 52 through holes (2.54mm pitch) exposing all pins from the MCU including 3x USART, 2x I2C, 3x SPI, 2x […]
Year 2019 in Review – Top 10 Posts and Stats
2019 is closing to an end, or you may already be into 2020 while reading this post. In any case, that means it’s time to look back at 2019 and look forward to the events and new products to take place next year. While 2018 was a boring year for new processors, 2019 brought us some interesting new chips such as Amlogic S922X / A311D, or the first Arm Cortex-A55 only processors such as Amlogic S905X3. Rockchip RK3399Pro was promising when it was announced last year, but it never really took off. It was a pretty quiet year for Allwinner as well. RISC-V architecture has been ramping up with the first general-purpose RISC-V MCU: GD32V, WCH CH572 Bluetooth LE MCU, the launch of more SiFive RISC-V cores, and Kendryte K210 RISC-V AI processor announced last year has found its way into more and more boards. There have also been the […]
OnLogic Introduces Four Apollo Lake Pico-ITX SBC’s with Integrated Heatsink
We previously covered some Apollo Lake Pico-ITX boards with the likes of GIGABYTE GA-PICO3350 or AAEON PICO-APL3 motherboards, but there are now more options with OnLogic – formerly known as Logic Supply – recently launching four Apollo Lake Pico-ITX SBC’s. OnLogic EPM160, EPM161, EPM162, and EPM163 are powered by either an Intel Celeron N3350 dual-core processor or an Intel Pentium N4200 quad-core SoC with different memory capacities, display and networking options.

UL IoT Security Rating System Ranks IoT Devices Security from Bronze to Diamond
Underwriters Labs (UL) is better known for its electrical safety certification programs, but in 2016, the company introduced three UL 2900 IoT security standards that defined requirements of software cybersecurity for network-connectable products. Four years later, you may not have heard many products adhering to UL 2900, and Laurens van Oijen, IoT security solution leader at UL, recognizes that ” the UL 2900 set the bar too high for most consumer electronics/IoT companies” according to a report on CE Pro. So instead the company has launched the UL IoT Security Rating System last May with 5 levels of “security capabilities” ranking IoT devices and products with either Bronze, Silver, Gold, Platinum, or Diamond. Those certifications are aimed to help both manufacturers and developers to improve the security of their solutions, and help consumers make better purchase decisions by knowing the level of security of IoT products by just looking at […]
