Tuya helps you easily Design & Manufacture your own Smart Home Solutions

I was recently informed about LSC Smart Connect 3 door sensor selling on Action discounter with over 600 stores across the Netherlands, Belgium, France, Germany, Luxembourg, Austria, and Poland. The door sensor is based on ESP8266, and people have bought a few and flashed their own open source firmware converting the device into a multi-purpose sensor device with ESPNOW protocol that enables direct and low-power control of Espressif devices without the need of a router. The module inside the door sensor is called TYWE3S, which one document on the FCC website refers to as “Tuya WiFi module” and further mentions “TYWE3S is a low-power consumption module with built-in Wi-Fi solution designed by Hangzhou Tuya Technology Corporation” that is based on ESP8266 WiSoC with 1MB flash, 50 kB RAM. One person in the LetsControlIt forum thread linked above explains the stock firmware can be updated over-the-air via a Raspberry Pi 3/3+ […]

HLK-7688A OpenWrt Development Board Comes with an Audio Jack

We first tested MediaTek MT7688 MIPS processor in Mediatek Labs’ LinkIt Smart 7688 / 7688 Duo hardware development kits running OpenWrt in 2015 with the boards having a focus on IoT applications. A year later, Widora NEO board launched with an audio jack for connected audio applications, but AFAIK it’s not available anymore. There’s now another OpenWrt audio board based on the processor with HLK-7688A board featuring Hi-Link HLK-7688A module which we previously found in MatchBox LoRaWAN gateway. HLK-7688A board specifications: Wireless Module – HLK-7688A based on MediaTek MT7688 MIPS24KEc processor @ 580 MHz, and equipped with 128MB RAM, 32MB flash Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps with u.FL antenna connector 10/100M Ethernet Audio – 3.5mm audio jack; 4-pin speaker header, WM8960 audio codec USB – 2x Micro USB ports one USB 2.0 port and one for debugging & power Expansion – […]

Giveaway Week – WisCellular NB-IoT & eMTC GPS Tracker

Rak Wireless WisCellular is an NB-IoT & eMTC Arduino shield based on Quectel BG96 module with 2G fallback that is similar to the company’s previous-generation WisLTE board, except it is certified for the global markets. I received a beta sample last year and went through the instructions to use it with a Hologram SIM card, but sadly I never managed to make it work, and eventually learned the Hologram SIM card did not support NB-IoT in Thailand. So I would have had to buy a local SIM card, but at the time, they didn’t sell those, and the only way to get an NB-IoT SIM card was to buy a development kit. Before going ahead with the purchase, I asked about coverage in my area but never managed to get a definitive answer so I gave up. So instead of keeping it in a drawer at home, I’d better just […]

Lenovo ThinkCentre M90n Nano IoT Fanless Mini PC is Powered by an Intel Whiskey Lake Processor

We’ve been covering mini PCs for several years, but I’ve just noticed we never wrote about Lenovo mini PCs probably as they were no that small, and higher price points. But today, I’ve come across Lenovo ThinkCentre M90n Nano IoT, a fanless mini PC powered by a dual-core Intel Celeron 4205U or Core i3-8145U Whiskey Lake processor. The mini PC also comes with 4GB DDR4, a 256GB SSD, DisplayPort video output, Gigabit Ethernet, several USB ports, two COM ports, and more. Lenovo ThinkCentre M90n Nano IoT specifications: SoC (one or the other) Intel Celeron 4205U dual-core Whiskey Lake processor @ 1.80 GHz with Intel UHD Graphics 610; 15W TDP Intel Core i3-8145U dual-core / four-thread Whiskey Lake processor @ 2.10 GHz (base) / 3.90 GHz (turbo) with Intel UHD Graphics 620; 15W TDP Memory – Up to 4GB DDR4 (on-board) Storage – 256GB or 512GB M.2 SSD Video Output – […]

STMicroelectronics Introduces Affordable LoRa Development Packs For All User Types

STMicroelectronics has recently announced the launch of a new set of LoRa Development packs, which are not only affordable, but they are aiming to a large pool of users from big organizations, small companies, hackers, engineers, students, and hobbyists. The ready-to-use development packs are aimed for applications bent on leveraging LoRa ’s long-range, low-power wireless IoT connectivity for tracking, positioning, metering, and many related applications. STMicroelectronics is releasing the P-NUCLEO-LRWAN2 pack and P-NUCLEO-LRWAN3 pack. Both packs provide a complete LoRaWAN development kit, and they include gateways, end-nodes, and ST tools, which are all based on the STM32 Nucleo evaluation boards. The LoRa gateway on both packs is based on the STM32 Nucleo-144 development board, NUCLEO-F746ZG. The STM32 Nucleo-144 development board with STM32F746ZG MCU supports Arduino, ST Zio, and Morpho connectivity. The Gateway header pins are exposed out to facilitate more development, and they support interfacing with LoRaWAN network-server providers LORIOT, Actility, myDevices Cayenne for LoRa […]
