Miracast Adapters Coming Up with Mediatek MT8636 SoC

It’s already possible to use Android mini-PCs such as T428 as a Miracast adapters, and we’ve also seen low cost HDMI dongles based on Actions Semi ATV6003 and Rockchip RK2928 that should eventually work as Miracast adapters, and sell for less than $30 retail. But there’s now a new SoC targeting DLNA/Miracast adapter: Mediatek MT8636. I don’t have any details about the SoC itself, but I could find a few Chinese company working on the solutions, and the most common is the one shown below, which can be called W18, SH-18, or WFD-04 depending on the company.

MT8636_Miracast_AdapterThe device is said to have the following specifications:

  • SoC – MT8636 highly integrated SOC
  • System Memory – 128MB DDR3 (TBC)
  • Storage – 128 MB Flash (TBC)
  • Wi-Fi – MT7601 WiFi 802.11b/g/n with Wi-Fi direct
  • Video Decode – 1080p H.264 (MPEG-4 AVC) CBP, MP, HP at L1 to 4.1
  • Audio Decode – LPCM and optional AAC
  • Video Output – HDMI V1.4,  HDCP 2.x (optional)
  • Wireless display content up to 1080p HD resolution, with latency <200ms
  • USB – microUSB for power
  • Power consumption – Up to 2.5W (5V/500mA)
  • Dimensions – 38 x 90mm

Hopefully the latency will be less than 100ms most of the time, and not just less than 200ms, as greater latency would affect the user experience. As usual, it’s very difficult to find the manufacturer, but I assume it could be Menoda Technology, a Shenzhen based manufacturer, that sells the device as W18. There’s also another company called RFTech that makes CPM218, a device with similar internal specifications, but a different enclosure.

The only information about price I could currently find is a 50 pieces lot on Aliexpress that goes for $45 per unit, which IMHO is too high for this type of product. There’s also a quick start guide on this Aliexpress page that shows the list of supported devices including Samsung Galaxy S4/S3/Note II/Note 10.1, Nexus 4, LG Optimus G, etc…

[Update: W18 is available for $32 including shipping on AliExpress]

    Looks very similar to this: http://www.ebay.fr/itm/HDMI-1080P-Wireless-Wifi-Video-Audio-Bridge-Miracast-USB-Screen-Sharing-DLNA-/300932813396?pt=LH_DefaultDomain_15&hash=item4610fe5254
    I found some on ebay but the sellers couldn’t actually confirm the spec…. -.-‘
    If i could be sure it play miracast then i would definitely buy it..

    This one seems to be ok and at least this is a powerful android stick.
    The seller said that it actually works as a Miracast receiver.

    But this solution is expensive and TV USB port would not be enough to power it up 🙁

    RK3188 HDMI TV Sticks such as the one you linked to can support Miracast, as long as the firmware is new enough

    I`m waiting for cheap devices supporting DLNA, love “play to” on windows.

    There are already HDMI Sticks available for about $30 for DLNA.

    Though I hardly know what miracast and dlna is – just yesterday I read on the box of my Jesurun A19 (Allwinner A20) Miracast, DLNA, Openmax, Google TV remote, while it is -not- mentioned in the specs
