Waveshare DVK512 Kits For Raspberry Pi Model B+ Include RTC, Sensors, LCD Display, and More

Beaglebone (Black) expansion boards are called capes, Minnowboard ones are lures, and Raspberry Pi model B+ add-on boards can be HATs (HArdware on Top). When I found a kit for the Raspberry Pi model B+ on DealExtreme, based on Waveshare DVK512 add-ons board I thought it might have found a Chinese HAT, but unfortunately it is not compliant with HAT board specifications as it misses an EEPROM,and the dimensions are not the correct one either. Nevertheless, the kit, as well as extra accessories such as a 3.2″ LCD display, can still be interesting. The kit on DX comes with the following items: DVK512 expansion board that connects to the 40-pin Raspberry Pi B+ header and features PCF8563 RTC chip with battery, an on-board USB to TTL chip for debugging via micro USB, a character LCD interface, connectors for modules connected via UART, SPIO, I2C or GPIO, various jumpers and user […]

MYIR ARM9 Linux Development Boards & Computer-on-Modules Powered by Freescale i.MX28 Processor

MYIR MYD-IMX28X development boards and MYC-IMX28X CPU modules had been announced in May 2014, but I’ve just found out about them via the company’s newsletter. The CoMs are powered by Freescale i.MX28 ARM9 processors (i.MX283 or i.MX287), feature 128 MB RAM, 256 MB Flash, and connect to a baseboard to make the development boards. Target applications include smart gateways, human-machine interfaces (HMIs), handheld devices, scanners, portable medical, experimental education as well as other industrial applications. MYC-IMX28X CoMs MYC-IMX28X computer-on-module specifications: Processor – Freescale i.MX283 or i.MX287 ARM926EJ-STM processor up to 454MHz with 128KB SRAM, 128KB ROM, 1280 bits of OCOTP ROM, 16KB/32KB I and D Cache System Memory – 128MB DDR2 SDRAM Storage – 256MB NAND flash, 128KB SPI flash Connectivity – On-board Ethernet PHY Connectors – 2x 1.27mm pitch 2 x 40-pin SMT male expansion connectors with access to Ethernet – Up to 2 Ethernet (two for i.MX287, one for i.MX283) USB […]

MIPS Creator CI20 Development Board Powered by Ingenic JZ4780 SoC

There are plenty of ARM based development boards running Linux and Android, but with MIPS it’s a different story. Microchip does have some affordable development board powered by their MIPS MCUs, but these don’t have the hardware specs to run Linux based operating systems, and Ingenic Newton Platform for wearables can run Android and Linux, but it appears to be reversed to companies with virtual no documentation. There are some MIPS platform running OpenWRT on hardware such as routers or Wi-Fi boards, but these can’t be considered fully supported development boards. But Imagination Technologies is trying to make MIPS more relevant, first by launching Prpl developers’ community, and MIPS Creator CI20 development board powered by Ingenic JZ4780 dual core MIPS32 (Xburst) core processor with PowerVR SGX540 GPU should soon be available with complete documentation and source code. Let’s go through the hardware specifications first: SoC – Ingenic JZ4780 dual core […]

Parallax Propeller 1 P8X32A Open Source Multi-core MCU

Lots of electronics devices are now powered by open source software such as Linux, open source hardware is not as wide-spread, but gaining tracking traction thanks to the like of Arduino, Beagleboard.org, Olimex, and many projects on crowdfunding websites, and now we even start seeing some open source silicon. Existing open source processors include LEON3 (SparkV8) MCU, OpenRisc, and just very recently, LowRISC, based on 64-bit RISC-V instruction set architecture, has been announced with the backing of some of Raspberry Pi co-founders, Google ATAP, etc… and is currently being developed at the University of Cambridge, UK. Parallax Propeller 1 P8X32A is another MCU which has been open sourced last week. Propeller 1 P8X32A had however been released in April 2006, and can be sourced as a 40-pin DIP chip for prototyping, and 44-pin QFP and QFN for production, and come with the following key features: Power Requirements: 3.3 VDC […]

Rockchip RK3288 Temperature Testing and Antutu Benchmarks

There are many upcoming Rockchip RK3288 based devices, and in the listing the CPU frequency varies from 1.6 GHz to 2.0 Ghz. so it’s difficult to know exactly what to expect. Ugoos has done some testing with their UT3 board measuring temperature after Antutu benchmark for different CPU clock frequencies and fan/fanless combinations. The board comes with a rather tiny heatsink which may explain some of the results below. They also added a small fan on top in about half the tests to compare the temperature against an heatsink only solution. Without further delays let’s go through the results: Frequency Antutu Score Temperature (heatsink) Temperature (Back of PCB) Heatsink only Heatsink + fan Heatsink only Heatsink + fan 1.608 GHz 38655 67 °C N/A 70 °C N/A 1.704 GHz 39853 72 °C 50 °C 75 °C 60 °C 1.800 GHz 41440 83 °C 52 °C 85 °C 62 °C 1.920 […]

OpenELEC Ported to TBS 2910 Matrix Board Supports DVB T/S/C, DVR and IPTV Server Functions

TBS 2910 Matrix, also simply called TBS Matrix, is a board powered by Freescale i.MX6 Quad SoC with 2GB RAM, 16 GB eMMC, and supporting various TBS USB DVB tuners. The company provides images for Ubuntu, Android, and something called Matrix TV. The company also releases the source code for the boards, and two OpenELEC developers, namely Ovi and Vpeter, though it could be a nice idea to port OpenELEC to TBS Matrix, and that’s exactly what they did. The video demo below shows online video streaming via 1channels add-on, which can be done with any Android or Linux media player running XBMC or OpenELEC, but the second part is more interesting, as it shows Live TV from a Cable TV USB tuner connected to the board. Ovi also confirmed the system supports DVR, and you can also use the board as a micro IPTV server. DVR function is supported […]
