Google may just have released Android Things operating systems for IoT applications, but its big brother – Android – has already gotten into some other IoT systems such as Quectel SC20 module powered by a Qualcomm processor and supporting LTE, WiFi, Bluetooth LE, and GNSS functions. Quectel SC20 comes in different flavors to cater for various markets, but all module share most of the same specifications: SoC – Unnamed Qualcomm processor System Memory – TBD Storage – 8GB flash Cellular Connectivity – FDD LTE, TDD LTE, TD-SCDMA, EVDO/DCMA, WCDMA, and GSM; antenna: MIMO 2×2, supports Rx-diversity Other Wireless Connectivity WiFi – 2.4GHz 802.11b/g/n (SC20-CE/-W); Dual band 802.11a/b/g/n/ac (SC20-E/-A/-AU/-J) Bluetooth 2.1+EDR/3.0/4.1 LE GNSS – GPS, GLONASS, and BeiDou Interfaces LCD – 4x lanes MIPI-DSI, 1.5Gbps each, HD (720p) @ 60fps Camera – MIPI-CSI, up to 1.5Gbps per lane, supports two cameras 2-lane MIPI_CSI for rear camera, up to 8MP 1-lane MIPI_CSI […]
$24 Winkel Arduino Compatible Board Includes WiFi, Bluetooth, 2.4 GHz RF, and an RTC (Crowdfunding)
There are plenty of Arduino compatible boards with WiFi based on ESP8266 WiSoC going for around $5 to $10, and with ESP32 processor, we are starting to have $15 to $20 boards with both WiFi and Bluetooth, but while ESP-IDF SDK has been progressing nicely, some parts of Bluetooth functionality are still not implemented. Winkel board offers an interesting alternative by offering WiFi, Bluetooth, 2.4GHz ISM, and an RTC for $24.

You Can Buy AirPods-like Wireless Bluetooth Stereo Earbuds for $16 and Up
Most Bluetooth headsets on the market actually come with some sort of wire or holding mechanism, which may not always be convenient, for example I can’t use mine comfortably while lying down on the bed. But that to electronics miniaturization, companies have recently started to offer truly wireless Bluetooth earbuds, including Apple’s yet-to-be available $159 Airpods. This morning I noticed two similar products in new arrivals list, first with $59.99 QCY Q29 mini Earburds on GeekBuying, and then even cheaper, but not quite as good looking (and likely not so good sounding), “FreeStereo Twins Wireless Bluetooth v4.1 In-Ear Headset w/ Mic” on DealExtreme going for just $22.25 including shipping. Let’s start with QCY Q29 earbuds specifications: Connectivity – Bluetooth 4.1 with HFP, HSP, A2DP, AVRC protocols support; up to 5-10 meter range Built-in Microphone Charging port – pogo on earbuds, micro USB to storage/charging box Battery – 45mAh for up […]

ESP32 Updates – ESP32-S Module Replaces ESP3212, ESP32 DevBoards for Sale, Arduino & NodeMCU Support
There have been some developments with regards to Espressif ESP32 in the last month since my post about upcoming ESP32 development boards. First ESP3212 module is no more, and has been replaced with ESP32-S module with about the same features, but it’s not pin-to-pin compatible, so the new module won’t work with older breakout boards made for ESP3212. ESP32-S is now out of stock on Seeed Studio, but you’ll find it on IC Station, Banggood, and others shops. One good news is that it’s now easier to buy – or at least pre-order – ESP32 development boards, although stock may still be an issue, as the platform is very popular. If you live in the US, you can now backorder “Sparkfun ESP32 Thing” for $19.95. ESP32 board can be powered by either a micro USB power supply or a LiPo battery, and exposes close to 30 I/O pins.
