Rikomagic RKM V3 Rockchip RK3328 TV Stick Launched for $63

We’ll know find plenty of devices powered by Rockchip RK3328 from TV boxes to development boards, but if you are interested in getting an Android TV stick based on the processor, I’m only aware of Rikomagic RKM V3 which the company unveiled in September. However, at the time the TV dongle was not for sale yet, and the company has just launched it for $62.90 including shipping on Aliexpress. RKM V3 specifications have not changed since the announcement, except we can have info about size and weight: SoC – Rockchip RK3328 quad core Cortex A53 processor @ 1.5 GHz with Mali-450MP2 GPU System Memory – 2 GB RAM Storage – 8 GB eMMC flash + micro SD card up to 32 GB Video & Audio Output – HDMI 2.0a up to 4K @ 60 Hz with HDR10 and HLG support Video Codec – 4K VP9, H.265 and H.264. 1080p VC-1, […]

Giveaway Week – NanoPi K2 Development Board

NanoPi K2 development board is powered by Amlogic S905 processor coupled with 2GB RAM, and follows Raspberry Pi 3 form factor, and I’ve got a K2 multimedia kit to give away courtesy of FriendlyELEC who sent me one a few months ago. The kit includes the board, a quick start guide, a fansink, a USB cable for power, an acrylic case (not shown above), and an IR remote control. I got it when I asked for NanoPi NAS Kit, and sadly I did not find the time to test it, but the company provides both Android 5.1 and Ubuntu 16.04.2 images for the board, and Armbian also released an experimental Ubuntu server image with mainline kernel, and an Ubuntu desktop “testing” image with legacy Linux. To enter the draw simply leave a comment below. Other rules are as follows: Only one entry per contest. I will filter out entries with […]

Testing Google’s GNSS Analysis Tool for GPS, GLONASS, Galileo, Beidou…

Google has recently released GNSS Analysis Tool to process and analyze Global Navigation Satellite System (GNSS) raw measurements from Android devices. This is mostly designed to enable manufacturers to see whether their GNSS receivers are working as expected. The tool can also be used for research and to learn more about GNSS, and there are two components: GNSS Analysis tool itself available for Windows, Linux, or Mac OS X GNSS Data Logger app working with Android 7.0 or greater phones that support raw measurements. You can download both from the release page on Github. I’ve given it a try with a computer running Ubuntu 16.04 and Xiaomi Mi A1 smartphone, but you can the analysis tool even f you don’t have Android 7.0+ smartphone, as sample data is included. I downloaded GnssAnalysisLinuxV2.4.0.0.zip, and extracted the content in ~/Desktop/GnnsAnalysisFiles directory as instructed. Now we can open a terminal window and install […]

2017 Singles’ Day Promotions on Chinese Online Stores

Singles’ day (Guanggun Jie – 光棍节) is celebrated every year on November 11 (11.11) in China, and retailers launch promotions to attract young shoppers, especially online. Last year Singles’ day was even bigger than Black Friday and Cyber Monday in the US terms of (online?) sales,with an estimated 20 billions dollars of goods moved. Online Chinese retailers that cater to overseas market bring their promotions to the international stage, and like last year, I’ve gather some of the Singles’ day promos launched by the most popular e-retailers in China. GearBest 11.11 Sale / Double Eleven promotion will span from November 1 until November 13, with Day 1-7 being the preheat period, abd 8-13 the formal time for the promotion. The event includes flash sales for all sort of items, “lucky bags” where you buy something cheap but do not know exactly what it is…, promotions for top brands (Vernee, Creality, […]

Arm Announces Mali-D71 for 4K/120 Hz Displays, Assertive Display 5 with HDR

Arm has just announced Mali-D71 display processor optimized for 4K120 displays used for virtual reality, Assertive Display 5 display management core which adds support for high dynamic range (HDR10 / HLG), as well as CoreLink MMU-600 system memory management unit to handle data feed to Mali-D71, with the integration leading to a 55% area saving for the combined solution and a 50% latency improvement. Mali-D71 Display Processor The main advantages of D71 display processor include: 30% system power savings by fully offloading GPU workloads before output such as composition, rotation, high-quality scaling, and other imaging processing in fixed function hardware. 2x area efficiency compared to Mali-DP650. When driving a single display, it can re-use the resources of a secondary display, doubling the performance. 4x latency tolerance – Mali-D71 can sustain up to 4x the delay on the system bus for the same throughput, helping maintaining high refresh rates up to […]

Giveaway Week – ESP32 PICO Kit v3 Boards

I don’t have one, but eight boards to give away to four winners (2 each) with Espressif Systems ESP32 PICO Kit v3 board based on ESP32-PICO-D4 SIP, an all-in one package with ESP32, 4MB SPI flash, crystal oscillator, and passive components, which allows for smaller boards. The board is very similar to any other ESP32 boards, and software compatible, but it’s just quite thinner, and easier to work with on breadboards. Since I had already played with Arduino Core and Espruino (JavaScript) on other boards, I used one of the 10 boards provided by Espressif to play with Micropyhon on ESP32. Each winner will get two ESP32 PICO Core board in order to make it worthwhile with regards to shipping costs. To enter the draw simply leave a comment below. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or […]

SAMA5D2 Based SiPs Combine ARM Cortex-A5 Processor With Up to 128MB DDR2

Atmel SAMA5D2 ARM Cortex-A5 processor was released about two years ago with extended temperature range and lower power consumption compared to previous SAMAD5 processors, with the new SoC still targeting industrial Internet of Things (IIoT), wearables and point of sale applications. In recent years, we’ve seen companies packing main components into systems-in-package (SiP) with products such as Octavo Systems OSD3358 and Espressif Systems ESP32-PICO-D4 with integrate an existing processor with memory, storage, and/or PMIC. Microchip (previously Atmel) has now done the same for their SAMA5D2 processors with SiPs combining the Cortex A5 SoC with DDR2 memory. Four SAMA5D2 SiPs have been launched: ATSAMA5D225C-D1M based on ATSAMA5D22C MPU with extra SD/SDIO, QSPI, FLEXCOMs (2x), I2S, and timers (2x) and: 128 Mb (16 MB) DDR2 DRAM 90 Peripheral I/Os 196 BGA Package Designed for RTOS/bare metal development ATSAMA5D27C-D5M based on ATSAMA5D27C MPU with: 512 Mb (64 MB) DDR2 DRAM 128 Peripheral I/Os […]

WCH CH340E is a Tiny 10-Pin Serial to USB Chip

I own a bunch of  USB to serial debug board based on CH340G/T or PL2303HX, and all include a crystal on the board with the exception of Hardkernel’s USB-UART module kit based on CP2104 (QFN24 package) working without crystal, hence smaller than most, but a bit more expensive than most. WCH has just released a new form version of their CH340 that does not require a crystal, comes in a tiny (3x3mm) MSOP10 package, and costs about 42 cents on Electrodragon (5 pieces). You’ll also find it for as low as 1 CNY ($0.15) on 1688.com. CH340E is slightly more expensive than CH340G, but considering you don’t need a crystal, and it will take less space on your PCB, total BoM cost for this USB to TTL function should be lower. Electrodragon reports that only two external parts are required, and they tested it up to 150,000 baud to flash […]
