HiMedia Q30 TV Box Review – Part 2: Android 7.0 Nougat Firmware

HiMedia Q30 is an Android Nougat TV box powered by Hisilicon Hi3798MV200 processor, a cost-down version of Hi3798C V200 processor with the same CPU, a lower-end Mali-450MP GPU, about the same media capabilities, and less I/Os. I’ve taken pictures of the device and board if the first part of the review entitled “HiMedia Q30 (Hisilicon Hi3798MV200) Android TV Box Review – Part 1: Unboxing and Teardown“, so today, I’ll report about my experience with the device while running Android 7.0. First Boot, Setup, and First Impressions I’ve connected a USB 3.0 hard drive to the single USB 3.0 port, and filled the two other USB 2.0 ports with a USB keyboard, and a USB hub with two RF dongles for an air mouse and a gamepad. I added Ethernet, HDMI, and power cable to start the device. A typical boot takes around 25 seconds to the Android launcher below. That’s […]

Cubieboard7 Board Powered by Actions Semi S700 Processor Becomes a Full-Featured Devkit with DVK522 Expansion Board

Cubieboard6 was announced earlier this year with the same form factor as Cubieboard2 – which was popular a few years ago – by replacing Allwinner A20 with Actions Semi S500 quad core ARM Cortex A9 processor. CubieTech is about to launch Cubieboard7 based on the same design, except for the processor upgrade to the pin-to-pin compatible Actions Semi S700 quad core ARM Cortex A53 processor. I’ve also found out Cubieboard2/6/7 can be connected to DVK522 expansion board to provide easier access more I/Os like LVDS, RGB LCD, VGA, and so on. Let’s start with the Cubieboard7 (CB7) preliminary specifications: SoC – Actions Semi S700 quad core ARM Cortex-A53 processor with Mali-450MP4 GPU System Memory – 2GB LPDDR3 Storage 8GB eMMC flash SATA 3.0 port for 2.5″ HDD/SSD implemented via USB 3.0 switch and JMicron JMS578 USB 3.0 to SATA controller. micro SD card slot up to 32GB Video Output – […]

Variscite DART-6UL SoM, an Alternative to Intel Edison Module

Intel recently announced it will discontinue manufacturing and selling all SKUs of the Intel® Edison compute modules and developer kits. The initial version of Edison was released in the beginning of 2014, with a second version being released by the end of 2014. It was intended for the IoT market, with dimensions of 35.5x25x3.9mm. The Edison features an Intel Atom processor, consisting of two Atom Silvermont cores running at 500MHz. It includes a fixed configuration of 1GB integrated RAM, and 4GB eMMC flash on-board. Dual-band (2.4GHz and 5GHz) Wi-Fi, Bluetooth 4.0 and USB controllers complete the package. According to Intel’s announcement, the last shipment of Edison family boards is planned for December 2017. This announcement will have a critical impact on companies that already integrated the Edison board in their products, as well as the many companies that engaged in the development process of integrating the Edison board into their products. While some of these companies are rushing to place […]

Sonnet is a Rugged Portable Device Creating Mesh Networks for Smartphones

Cellular networks are available in most places, but not always, and you may not have connectivity while climbing mountains or other remote locations, when going abroad, during natural disaster, in very crowded places where network capacity is exceeded, or when your government decides to cut it off for “national stability and harmony”. Wouldn’t it be great if you were still able to contact with your friend in such cases, and create your own mesh networks expanding over several kilometers? That’s exactly what Sonnet does by connecting to your smartphone over WiFi, and to other Sonnet nodes over ISM frequencies (433, 868 and 925 MHz). Sonnet hardware specifications: Connectivity 802.11 b/g/n WiFi with up to 20 dBm (max varies per country); WPA/WPA2 security Long Range RF Frequencies 915 MHz (North America) 868 MHz (Europe) 433 MHz (Asia Pacific) Distance – 5km typ.; up to 10km Line-of-sight; SMA connector available to extend […]

TinyLIDAR is a $15 LIDAR MCU Board based on STMicro VL53L0X Time-of-Flight Ranging Sensor (Crowdfunding)

LIDAR (Light Detection and Ranging) technology is used in autonomous car, drones, and some smartphones, in order to get an object position just like RADAR systems, but instead of using radio frequencies, it relies on infrared signals. High speed, long range LIDAR systems can cost several hundred dollars, but if you’d like to experiment with the technology, or your project would work just fine with 60 Hz scanning and a 2 meter range, tinyLIDAR could be a fun board to play with using Arduino compatible boards. TinyLIDAR specifications and features: LIDAR Sensor ST VL53L0X Time-of-Flight (ToF) ranging sensor 940nm laser VCSEL Up to 2 meters range Up to 60 Hz sampling rate even with Arduino UNO board Up to 3% accuracy with mm precision MCU – Unnamed dedicated 32-bit MCU (likely STM32) used to abstract the ST PAL API into simple I2C commands Host Interface – 4-pin I2C header; re-configurable […]

Sonoff G1 AC Powered Smart Power Switch Works Over 2G GSM/GPRS

Today, I’ve searched for AC powered wireless switched similar to Sonoff devices, but with ESP32 instead in order to get WiFi and Bluetooth, since the latter is better to use with a battery powered buttons. I did find a DC powered board, but no AC powered ones yet. However, as I visited ITEAD website to check if they had anything of the sort, I discovered they had a new model called Sonoff G1, similar to Sonoff TH16, but instead of using WiFi, you can use 2G GSM/GPRS to control the switch remotely. Sonoff G1 specifications: Wireless Module – ST86 quad band GSM/GPRS module GSM/GPRS connectivity GSM850, EGSM900, DCS1800 and PCS1900 MHz support GPRS multi-slot class 10, GPRS mobile station class B 1.8V, 3V SIM card slot Transmit power: Class 4 (2W): GSM850, EGSM900; Class 1 (1W): DCS1800, PCS1900 Relay – Up to 16A (3000 Watts max) Terminals – 6 terminals […]
