$10 Rockchip Miracast dongle contains RK2928 SoC CPU

miracastIt really is a sign of just how cheap ARM-based CPUs have become with Rockchip recently showing off to ARMdevices.net a concept Miracast dongle running a compact fixed Linux distro on a single-core Rockchip RK2928 SoC CPU. Using the chip, the dongle can create a WiFi-Direct connection with any Android device with WiFi-Direct support and Android 4.2 (Jelly Bean) operating system.

The RK2928 chip features a single-core Cortex A9 processor with ARM Mali-400 graphics engine, clocking at up to 1.2GHz. Rockchip believes that phone makers could offer the dongle as part of a bundle or sell it for $10, which shows just how cheap this technology has become. Essentially, this is a single-function mini PC with a microUSB port for power, the WiFi-Direct connection and an HDMI plug on the end. With all of that, it turns any TV or monitor into a wireless display.

Rockchip says the system as it is now has a delay of 80-milliseconds, but on the video below, it looks fast enough to be able to playback videos itself. The dongle appears easy to use – there’s no password or anything, in fact, it’s easier to connect up than a Bluetooth audio dongle.¬†With many late-model Android phones including MHL (mobile high-definition link) that adds HDMI to the microUSB OTG port, this low-cost dongle could bypass all of that and turn any Android 4.2 or later phone/tablet into a big-screen ready video player.

We don’t know if/when the dongle might hit the streets but it’s definitely worth keeping an eye out for.
