Add Wireless Charging to (Almost) Any Smartphone or Tablet

October 27th, 2014 5 comments

Flagship mobile devices often come with wireless charging capability, but there’s an easy way to add (Qi) wireless charging to almost any smartphone, or possibly tablet, thanks to wireless charging receivers that simply connect to the micro USB port of your mobile device, and can be purchased for as low as $7 on Aliexpress, Ebay, DX.com, etc… I’ve also seen Adafruit made a Qi Wireless Receiver module for Arduino with a 2.54mm pitch connector.

Qi_Wireless_Charger_ReceiverThey come in various sizes and shapes, but they’re all extra thin (1 mm), with a micro USB connector oriented upwards or downwards depending on your mode, and a thin cable, that allows you to place it inside your phone between the battery and the phone cover as shown in the picture below. It’s not always possible however, as for example the receiver would cover my phone’s rear camera lens, but you could always attach it to a protective cover, or a car phone holder.

Once the installation is complete, you are ready to charge your phone with a wireless charger.

Specifications ARE different between modules, but typically look like:

  • Dimensions – 62 x 45 x 1.1mm
  • Net weight – 2.5g
  • Input Power – 3.5W
  • Output – DC5V/650mA (Average)
  • Charging current – DC5V/500mA (Average)
  • Working life – 4000 charges

October 25th, 2014 5 comments

LG has been making mobile devices since 1997, has entered the smartphone market in 2010, and they’ve now decided to foray into mobile SoC, with their very first SoC being an octa-core Cortex A15/A7 processor called NUCLUN, and found in their latest G3 Screen smartphone running Android 4.4.4.

LG_G3_Screen_NUCLUN_Processor

Details about NUCLUN processor are sparse, but the company did provide some specifications for LG G3 Screen smartphone:

  • SoC – LG NUCLUN (LG7111) Octa-Core big.LITTLE processor with four ARM Cortex A15 cores @ 1.5GHz, four ARM Cortex A7 cores @ 1.2GHz.
  • System Memory – 2GB RAM

Samsung Officially Announces Exynos 7 Octa big.LITTLE ARM Cortex A53/A57 Processor

October 16th, 2014 7 comments

Samsung started to commit code related to Exynos 7 processor to mainline kernel in August, but at the time details were scarce, and many tech websites referred to a Exynos 5433 64-bit processor from Samsung. Exynos 5433 for a Cortex A53/A57 SoC did not make much sense as the company recently announced Exynos 5430 based on Cortex A15 and A7 cores, so finally Exynos 5433 has been renamed to Exynos 7 Octa.

Exynos_7_OctaHere’s what we know about Exynos 7 Octa from information on Exynos 7 Octa page and an older Anandtech article about Exynos 5433:

  • CPU – 4x Cortex A57 cores @ 1.9 GHz , 4x Cortex A53 cores @ 1.3 GHz
  • GPU – Mali-T760 @ 700 MHz
  • Memory Controller – 2x 32-bit @ 825MHz (13.2GB/s b/w)
  • Display – Up to WQHD (2560 x 1440) / WQXGA (2560 x 1600) resolutions
  • Video – Advanced multimedia format codec (MFC) including support for H.265/HEVC @ 60 fps
  • Camera – Up to 16 MP 30fps rear camera, Up to 5MP / 30 fps front-facing camera, with dual ISP allowing for simultaneous video recording.
  • Process – 20 nm HKMG

A57 cores are said to provide 57% more performance than the A15 cores found in Exynos 5 Octa processors, whereas. Mali-T760 GPU should deliver up to 74% enhanced graphics performance over Mali-T628 used in Exynos 5 Octa.

Samsung Exynos 7 is used in the international version of the Galaxy Note 4 smartphone.

Intel / Rockchip XMM 6321 Solution for Low Cost 3G Smartphones and Tablets

October 16th, 2014 4 comments

Back in May, Intel and Rockchip announced a partnership to develop 3G and LTE “Sofia” SoC for mobile devices, a few months later, Rockchip VP posted a picture of dual core development board (6321 solution) on Weibo with Rockchip and Intel technology, and the companies have showcased solutions based on XMM 6321 during the Hong Kong Electronics Fair.
XMM6321_XG632_AG620Intel XMM 6321 appears to be a two-chip solution comprised of:

  • XG632 SoC with a dual core Intel processor, a GPU, ISP?, VPU and a 2G/3G modem
  • Intel/Infineon AG620 Communication Combo with 2G/3G RF, Wi-Fi/BT, GPS, GLONASS and Audio/PMU.

XG632 will be the first processor from Intel and Rockchip collaboration, but it may not be part of “Sofia” family. with quad core 64-bit Sofia 3G-R and Sofia LTE SoCs coming at later date. XG632 is for entry-level smartphones (<$30) and tablets (<$40), whereas the upcoming Sofia SoCs will be seen in mainstream devices.

Charbax filmed Rockchip solutions at Hong Kong Electronics Fair, and he claims XG632 is actually a dual ARM Cortex A5 processor, but this is not consistent with the diagram above showing an “Intel Dual-Core”, and I could not confirm it with any other news sources, so wait and see.

Mediatek Releases Android SDK with APIs for HotKnot, Video & Image Processing, Multi-SIM, etc…

September 22nd, 2014 3 comments

Mediatek seems motivated in getting involved with maker and open source communities. Thanks to its works on Android One with Google, the company recently released the Linux kernel source for MT6582 processor, and with a separate endeavour, launched Mediatek Labs bringing LinkIt ONE platform for IoT and wearables to market, as well as a preview release of an Android SDK for its mobile processors.

Features of the SDK includes:

  • Set of libraries for MediaTek feature APIs with full API documentation.
  • x86 MediaTek emulator based on a reference implementation of an Android 4.4.2 (KitKat) device powered by a MediaTek chip, adding capabilities to test and debug telephony and multi-SIM features, a vibrator indicator and a hot-swappable SD card.
  • Customized version of the DDMS (Dalvik Debug Monitor Server), which adds support for testing telephony features, such as plugging and unplugging a headset, sending telephony commands to test call and SMS features, etc…

Mediatek_Android_SDKYou can download the Android SDK after registration, on Mediatek Labs’ Android SDK page.

The SDK contains two zipped files:

  • mediatek_android_sdk_api-19.3.1.zip including several folders:
    • emulator – Linux and Windows executables.
    • images – Images needed by emulator.
    • libs – API libraries.
    • samples – API sample applications.
    • skins – 720p / 1080p skin for emulator.
    • doc – SDK documentation
  • mediatek_android_sdk_tools-19.3.2.1.zip with two folders:
    • ddms-linux-x86_64 – MediaTek customized DDMS (Linux version)
    • ddms-win – MediaTek customized DDMS (Windows version)

The current APIs have three levels, and allow app developer to access:

  • Multi-SIM Telephony
  • Audio / Video
  • Camera MAV (Multiple Angle View) to create 3D and other effects
  • HotKnot (Mediatek’s alternative to NFC)
  • Portrait Enhancements using features such as skin smoothing and eye enlargement
  • Image Transformation such as flip, rotate, and sharpen (hardware accelerated)
  • Gesture, for instance, detection of open palm and victory (V) hand gestures
  • API Level Version Check

You can also consult the API documentation online, and to get started download MediaTek SDK for Android Developer’s Guide. Although many of the API features can be tested on the emulator, you’ll probably want to do some testing on actual phones, and Mediatek will soon provide a list of reference Android phones.

If you happen to live in the United Kingdom, Mediatek will showcase both LinkIt platform and their Android SDK in Manchester at XDA:devcon on September 26-28, 2014.
