Omate Rise is a $199 3G and WiFi Smartwatch Powered by Mediatek MT2601 SoC (Crowdfunding)

Most smartwatches sold on the western markets are designed to be smartphone’s companions, and only come with Bluetooth LE connectivity, while we’ve seen many smartwatches (aka watchphones) with SIM card slot originating from China in the past, including the lower end No.1 D3 smartwatch which I reviewed recently. But this may be changing, as Omate is going to launch a new smartwatch called Omate Rise that will include 3G connectivity via a micro SIM card slot, as well as WiFi, Bluetooth Smart, and GPS. Omate Rise specifications: SoC – Mediatek MT2601 dual core ARM Cortex A7 @ 1.2GHz with ARM Mali-400 MP GPU System Memory – 512MB RAM Storage – 4GB flash Display – 1.3″ round muti-touch color display with 360×360 resolution (Innolux) Connectivity – Bluetooth 4.1 LE (A2DP profile), WiFi 802.11 b/g/n, GPS Cellular Connectivity – 3.5G HSDPA (2100/1900 MHz), GPRS / EDGE /GSM (850/900/1800/1900 MHz); micro SIM card […]

Quick Start Guide for LinkIt Smart 7688 (Duo) Board

Mediatek Labs has announced LinkIt Smart 7688 development boards powered by Mediatek MT7688 WiSoC earlier today, but I was selected for a close beta several weeks before the launch, and I’ve had time to play a little with the boards, so today I’ll report my experience getting started with LinkIt Smart 7688 amd 7688 Duo by writing a Quick Start Guide showing how to setup the boards, upgrade firmware, access the serial console, run “Blink LED” sample applications with Python and JavaScript, as well as the Arduino IDE, and connect to the Internet. Initial Setup You’ll only need a micro USB cable and a computer with WiFi and USB ports to get started with the board. The green LED (top) for the MCU will turn on immediately, while the red LED (bottom) for WiFI will blink once, and only turn on continuously after 5 seconds, and within 30 seconds after […]

K1 Plus Amlogic S905 TV Box Review

Videostrong KI Plus is one of the first Amlogic S905 TV boxes to be launched on the market, and it also happens to be one of cheapest model selling for around $45 on various sites, and it’s even available for $39.99 on GearBest for Black Friday / Cyber Monday. I’ve posted the specifications and pictures of the device previously, and after updating the firmware, I’ve finally completed the review. First Boot, Settings and First Impressions As usual, I’ve connected a whole bunch of cables and peripherals to the device to make the power supply can handle it, including a USB hard drive, a USB webcam, a USB keyboard, a USB hub with two RF dongles for Tronsmart Mars G01 gamepad and MeLE F10 Deluxe air mouse, as well as a HDMI, optical audio and Ethernet cables, and a speaker connected to the 3.5mm AV jack and powered by one of […]

ESP32 Module Schematics and Board Files

Espressif teased about their ESP32 WiSoC with WiFi and Bluetooth LE a few weeks ago in a letter addressed to developers, but did not release that much information. The company has now released some documents in the forums (registration required) concerning ESP32 module including PCB processing requirement, schematics and PCB layout, and bill of materials. The very first modules will actually be based on ESP31 processor, which only slightly differs from ESP32 with some swapped pins. The BoM is pretty small with several capacitors and resistors, one inductance, a 26 MHz crystal, ESP31, and a Gigadevice flash. The schematics have been designed with Orcad 16.6, so if you don’t have the program, you can read the schematics with Orcad 16.6 Lite, which is free to download. I’ve also printed the schematics to a PDF file. I’m not sure how to open the .pcb file which should be the module’s PCB […]

Amlogic S905 Source Code Published – Linux, U-Boot, Mali-450 GPU and Other Drivers

Amlogic has an open linux website where they regurlarly release GPL source code, and with Amlogic S905 devices coming to market, they’ve released a few tarballs at the beginning of the month including Linux 3.14 source code, U-boot source code, and Mali-450MP GPU kernel source code (obviously not userspace), as well as some other drivers for WiFi, NAND flash, PMU, TVIN, etc… Let’s get to the download links: Linux 3.14.29 source code U-boot 2015.01 GPU drivers for ARM Mali-450MP Broadcom and Realtek Wifi drivers and firmware (November 4, 2015) can be found @ http://openlinux.amlogic.com:8000/download/ARM/wifi/. Other kernel modules (November 4, 2015) @ http://openlinux.amlogic.com:8000/download/ARM/modules/. I quickly tried to build the Linux source. If you’ve never build a 64-bit ARM kernel or app before, you’ll fist need to install the toolchain. I installed the one provided with Ubuntu 14.04:

sudo apt-get install gcc-aarch64-linux-gnu

1	sudo apt-get install gcc-aarch64-linux-gnu

Now extract the tarball and enter the source directory:

tar xvf arm-src-kernel-2015-11-04-9e845bea41.tar.gz 
cd arm-src-kernel-2015-11-04-9e845bea41

1 2	tar xvf arm-src-kernel-2015-11-04-9e845bea41.tar.gz cd arm-src-kernel-2015-11-04-9e845bea41

At first I […]

Newracom NRC6101 802.11ah WiFi SoC Promises up to 1 km Range for Smart Grid and Automation

802.11ah is a new WiFi standard operating in the 900 MHz range that targets low power & long range connectivity, as required by many IoT & M2M applications. According to this low power WAN standards comparison table, 802.11ah also supports up 1km range outdoor, 150 Kbps to 346 Mbps transfer rates, up 8191 clients per access points, and a 2016 launch is planned. However, I had not seen any implementations based on the new standard, except a demonstration by Antcor on a DSP in 2014. A Korean startup, Newracom, may however soon launch the first 802.11ah chip with NRC6101 SoC. I was tipped about this new solution via a Korean website, where I got the picture above from, but there’s no information about NRC6101 on the web, except for a small mention on Wikidevi.com redirecting to the product page, where NRC6101 name is not even mentioned, but with some specifications […]

Konke Mini K and Mini Pro Wifi Smart Sockets are Based on ESP8266 SoC

ESP8266 WiFi modules are very popular in the maker community, but so far I have not seen it in any devices myself, until I saw a tweet from @EspressifSystem about a Mini K smart socket. A search on Aliexpress lead me to two devices made by Konke, who also made Kankun KK-SP3 WiFi socket, with Mini K and Mini Pro smart sockets. Both models has basically the same features, except Mini-Pro adds infrared support: Connectivity – 802.11 b/g/n Rated Voltage – AC 100-240V 50/60Hz Rated Power – 2200 Watts Rated Current – 10A Charging Protection: Yes Misc – Power button, Infrared (Mini Pro model only) Plug – China / AU plugs Dimensions – 5.1 diameter x 2.7 cm (V0 grade PC material) Weight – 70 grams Both devices support on/off timers, cyclical delays and charge protection (turns off when devices are charged) with the Android or iOS app. I understand […]
