Giveaway Week – Khadas Vim Pro Development Board

For the final day of this giveaway week, I’ll send Khadas Vim Pro development board to a new home. The board is powered by an Amlogic S905X processor coupled with 2GB RAM and 16GB storage, features 10/100M Ethernet and 802.11ac WiFi, and support 4K video playback and output via its HDMI 2.0a port. The board supports various operating systems such as Android, LibreELEC, dual boot Android/Ubuntu, etc.. and I wrote a Ubuntu review / getting started guide for the board in February. At the time, the image was still “raw” with many steps to perform by the users, and part of the documentation needing to be worked on. But the company (Szwesion) and members of the community are usually active in resolving user issues on the forums. I’ll give away the kit I’ve received with the board in an acrylic case, a USB to USB type C cable for power, […]

Giveaway Week – Nextion Enhanced 7″ Capacitive Display

My Nextion Enhanced NX8048K070 display will soon find a new home. The 7″ display comes with a capacitive touchscreen, an enclosure, and can work in standalone mode thanks to a built-in processor and a 8-pin FPC connector for I/Os, or connected to a micro-controller through a UART interface. I did a mini review of the display, mostly showing a teardown, and how to use Nextion Display Editor Windows-only tool to design your own user interface. The GPIOs are not really convenient to use with the required flat cable, and the company did not send me their $5 IO board, which would have made things easier. Learning curve may be a little sharper than needed as I’ve not found the Windows software to be very user-friendly, and documentation could be improved too. I’ll give the display with enclosure, micro USB power board, and UART cable as shown on the first photo. […]

Lab in a Box Concept Embeds x86 Server and 6 ARM Boards into a PC Case for Automated Software Testing

The Linux kernel now has about 20 millions line of code, Arm has hundreds of licensees making thousands of processors and micro-controllers, which end up in maybe hundreds of thousands of different designs, many of which are not using Linux, but for those that do, Linux must be tested to make sure it works. The same stands true for any large software used on multiple hardware platforms. Manual testing is one way to do it, but it’s time consuming and expensive, so there are software and hardware continuous integration solutions to automate testing such as Linaro LAVA (Linaro Automated Validation Architecture), KernelCI automated Linux kernel testing, and Automotive Grade Linux CIAT that automatically test incoming patch series. Both CIAT and KernelCI focus on Linux, and rely on LAVA, with KernelCI leveraging hardware contributed by the community, and proven to be effective as since it’s been implemented, failed build configs dropped […]

Giveaway Week – Wio GPS Tracker Board

It’s Friday, and the fifth day of giveaway week on CNX Software. Today, I’ll be giving away Wio Tracker, an Arduino compatible board based on Microchip / Atmel SAMD21 ARM Cortex M0 MCU with GPS, Bluetooth, 2G GSM/GPRS connectivity. My review of the board was rather negative, as I only managed to make Bluetooth 3.0 work while following the documentation as it was back in May. Since then the documentation seems to have improved, and other people have been more successful than me, and made the blink LED, and GPS samples to work. This version of the board only support 2G, so make sure it is still supported in your region/country. 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 email address. Contests are open for 48 hours starting at […]

Panasonic Showcases Flexible Batteries with Wireless Charging System

Flexible batteries such as PowerStream lithium polymer batteries can be integrated into new application such as smartcards, and could help wearables have longer battery life by adding batteries into clothes, wristbands or chestbands for example. You’d still need to charge them however, and in some cases adding a USB port (micro USB or type C) may negate the benefit of having a thin flexible battery, but Panasonic has a solution as the company added wireless charging capability to their flexible batteries. The solutions showcased at Ceatec Japan 2017 on October 3-6, 2017 were flexible lithium-ion rechargeable batteries with 0.45mm thickness, and 18, 42 and 65mAh capacity. Battery voltage is 3.8V, charging voltage 4.35V, and the batteries can be bend up to a radius of 25 mm, and twisted by up 25°. Such batteries are meant to be attached to human body and clothes for medical and health management applications, or […]

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 […]
