ESP32-WROVER-KIT Devkit Supports Espressif ESP32 Modules, Includes a 3.2″ LCD Display

Yesterday Olimex wrote a blog post informing us that ESP32-CoreBoard was back in stock, one the many ESP32 boards launched late this year, but still hard to get. The company also mentioned they’d have limited quantity of the new ESP32-WROVER with JTAG and LCD display together with the picture below. ESP32 is quite more powerful than ESP8266 so it makes sense to have an ESP32 development kit with an LCD display. A quick DuckDuckGo search led me to ESP-WROVER-KIT Getting Started Guide, where we can find more details including the overall specifications: Compatible with ESP-WROOM-32 and ESP32-WROVER modules based on ESP32 dual core Tensilica L108 processor clocked at up to 240 MHz with WiFi and Bluetooth LE connectivity Storage – Micro SD slot Display – 3.2″ LCD display connected via SPI USB – 1x micro USB port Expansion 8-pin UART header 6-pin SPI header 48-pin header for I/Os and camera […]

LG TONE Wireless Bluetooth Speakers & Earbuds Get Charged with a Neckband

Battery powered Bluetooth speakers are very common, and Bluetooth earbuds even more, but both are normally designed for different use cases. Last year ZAGG decided to bring both into a single product that you wear around your neck: Flex Arc Wireless Bluetooth earbuds + speakers now selling for about $56. The obvious advantage is that it includes larger battery than you can fit in earbuds and most Bluetooth headsets. ZAGG will soon be getting some competition as LG has designed two Bluetooth audio products leveraging your neck with LG TONE Studio (HBS-W120) equipped with a Hi-Fi DAC, 4 speakers, and two earbuds, and LG TONE Free (HBS-F110) with 2 “true wireless” earbuds that can be storage and charged in their neckband. The latter can also vibrate for incoming calls and text messages. An extra charging cradle is also provided for use cases when the neckband might not be convenient. LG […]

433/868/915 MHz LoRa Modules Are Now Selling for $6 and Up

Market forecasts for the Internet of Things promise billions of connected device in the years to come, but this won’t happen when LPWAN  connector sensors cost $50 or more, so prices will have to come down. I’ve been told that one company is working on a WiFi + LoRa module that’s going to sell for $5 to $6 sometimes in 2017, but in the meantime, it’s possible to get some LoRa modules for less than $10, albeit limited to 433 MHz frequency not the more common 868 MHz (EU) and 915 MHz (US), thanks to products such as AI-Thinker Ra-02 module. Ra-02 specifications: Chipset – Semtech SX1278 low power long range transceiver Radio 433MHz frequency (420 to 450 MHz range) +20dBm – 10mW constant RF output vs. V supply; up to 300 kbps bitrate Supports FSK, GFSK, MSK, GMSK, LoRa and OOK Modulation Mode 127dB RSSI wave range.

RetrOrangePi 3.0 Retro Gaming & Media Center Firmware Released for Orange Pi H3 Boards and Beelink X2 TV Box

RetrOrangePi is a Linux distribution based on armbian transforming Allwinner H3 boards – mostly Orange Pi boards, but also Banana Pi M2+ and NanoPi boards – into entertainment centers to play retro games, and watch/listen media files (videos/music) using Kodi. If you don’t have a development board, or would prefer a complete solution with casing and power supply, Beelink X2 TV box is also supported. The developers had been recently working on rectifying some GPL issues, and they have released RetrOrangePi 3.0 images right before Christmas. RetrOrangePi 3.0 changelog and key features: Full Armbian 5.23 Jessie Desktop version with kernel 3.4.113 (backdoors fixed) Slim version 1st release (less than 2 GB) coming soon OpenELEC (Kodi Jarvis 16.1) with CEC support by Jernej Škrabec RetroPie-Setup version 4.1 New Kodi Krypton beta6 version New emulationstation-ROPI branch forked from jacobfk20 with gridview, on screen keyboard with easy wifi config and storage check with […]

vThings WiFi CO2 Monitor Quick Start Guide

I’ve already checked out vThings CO2 Monitor hardware and we’ve seen it’s based on ESPrino ESP8266 board, and my model includes CM1106 CO2 sensor and BMP180 temperature and pressure sensor. I’ve now installed it in my kitchen, about 3 to 4 meters from the gas stove, and getting data to ThingSpeak. The door and window of my kitchen are open all day, and the wall have ventilation holes. That’s important for CM1106 sensor since it auto calibrates every 3 days in clear air. If you plan to use such sensor in a closed environment, you should buy Vthings with CM1102 CO2 sensor that costs more, but does not require calibration. Since all WiFi systems I’ve just so far starting AP mode for configuration, I first looked for an access point, but… nothing… Then I decided to read the documentation (might be useful at times), and the monitor is actually configured […]
