Atomo is a Raspberry Pi Compatible Modular Electronics Prototyping System (Crowdfunding)

March 22nd, 2017 7 comments

Atomo is a modular electronics protyping system comprised of four elements: Control, I/O, Power, and Connector, with the PCBs for each category color-coded with respectively red, blue, green, and black. The connector board connects power, I/O and control(ler) boards together in a way that’s supposed to be neater than most hand made prototypes. The whole ecosystem includes 15 different boards: Controllers with 26-pin Raspberry Pi compatible header 2 IO Module Controller (CM-M2K22-A) based on NXP Kinetis K22F MCU 4 IO Module Controller (CM-M4K64-A) based on NXP Kinetis K64F MCU 8 IO Module Controller (CM-M8K64-A) based on NXP Kinetis K64F MCU Connectors 8 IO Module Connector (GM_M8P2_A) – Dim: 145mm x 100mm; power up to 40V @ 64A 4 IO Module Connector (GM_M4P1_A) – Dim: 71mm x 100mm; power up to 40V @ 32A 2 IO Module Connector (GM_M2P1_A) – Dim: 71mm x 65mm; power up to 40V @ 16A 2 IO Module Low-Power Connector (GM_M2P0_A) – Dim: 71mm x 65mm; Good for low power…

Mecool KIII Pro Hybrid STB Review – Part 2: Android Firmware, TV Center, and DVB-T2 & DVB-S2 App

March 22nd, 2017 30 comments

Last year I reviewed K1 Plus T2 S2, an Android TV box powered by Amlogic S905 quad core processor with DVB-T2 and DVB-S2 tuner support, which worked with some caveats. VideoStrong has now send me an updated model with Amlogic S912 octa-core processor, which I presented in the post entitled Mecool KIII Pro Hybrid Android STB Review – Part 1: Specs, Unboxing and Teardown, where I listed the specifications, and showed photos of the device and the boards (main board + tuner board). I’ve now had time to play with the device, and in many respects the user experience is very similar to the one I got with KI Plus T2 S2 models, but there are also some tweaks, and a few bugs which I’ll report in the second part of the review below. KIII Pro Hybrid TV Box Setup, Settings, & Power Consumption The four USB ports are really convenient, as I could connect a USB hard drive, an…

Khadas Vim Amlogic S905X Development Board Gets Android 7.1 Firmware and SDK

March 22nd, 2017 1 comment

Khadas Vim is a development board powered by Amlogic S905X quad core processor that officially supports Ubuntu 16.04, OpenELEC and Android 6.0. Shenzhen Wesion Technology , the maker of the board, has now released Android 7.1 firmware image and SDK for the board. As we’ve seen before Amlogic Android 7.1 SDK still relies on Linux 3.14.29, but Linux 4.4 is also in the works. If you want to give it a try on your board, download Vim_Nougat_170321.7z directly, or from the firmware download page. The current image installs to the eMMC flash via USB or a bootable micro SD card (Windows methods only), so it will wipe whatever OS you have already on the board. The firmware is based on the features of their Android 6.0.1 image, but upgraded to Android 7.1.1 with Chrome and Gapps (for Google Play Store support). Source code for the Android 7.1 SDK can be found via several repositories on Khadas Github account. Once the…

Google Releases Android O Developer Preview with UI & Audio Improvements, Better Performance, etc…

March 22nd, 2017 No comments

Nearly exactly one year after Android N developer preview release, Google has now announced the release of Android O developer preview in order to get feedback from the developer community before the official release of Android 8.0? Oreo? in Q3 2017. So what’s new so far in Android O? Here are some of the changes: Background activity limits –  Automatic limits on what apps can do in the background for implicit broadcasts, background services, and location updates. Notification channels –  New app-defined categories for notification content for better control from the use, as user may only block or change the behavior from one channel, instead of applying the same behavior to all notifications from a given app. For example, a News app may have notifications for Technology, Sports, Politics, International, etc… Autofill APIs – Platform support for autofill, where users can select an autofill app, similar to the way they select a keyboard app, with the app securely storing  addresses,…

ARM DynamIQ Improves on big.LITTLE Technology, Supports Up to 8 Heterogeneous Cores in a Single Cluster

March 21st, 2017 13 comments

ARM unveiled big.LITTLE technology in 2011 which consisted of clusters of low power cores such as Cortex A7 or A53, and high performance cores such as Cortex A15 or A72, with the system assigning tasks to the best processor for the job in order to  optimize battery life. big.LITTLE supports up to 4 cores per cluster, and you can mix different types of cores within a single cluster. ARM DynamIQ changes all that as up to 8 cores are supported within one cluster, and you can mix low power and high performance cores within a given cluster. ARM DynamIQ multicore microarchitecture will be available for all new ARM Cortex-A processors starting this year, and targets automotive, networking, server, and primary compute devices. ARM claims it’s especially advantageous for artificial intelligence due to better performance, and autonomous driving due to increased safety, and it allows for much faster response from accelerators. Based on the slide below showing the evolution of multi-core…
