When opened up the stick comprises of:
1 x Allwinner A31 CPU (clocked @ 1 Ghz)
2 x 32Gbit NAND (Hynix H27UBG8T2BTR-BC) = 8 GByte
8 x 2 Gbit DDR RAM (Hynix H5TQ2GB83CFR) = 2 GByte
1 x Wireless-BGN/BT daughter card (Realtek RTL8723) = max. 150mbps 2.4 GHz & BT 4.0
1 x AXP221 Power controller
The supplied ROM is based on Andriod 4.1 and as a little bonus supports the exFAT storage standard and hence can read 64 Gb micro SDXC cards. Nice!
The kernel is fixed at 1280 x 720 and there is no alternative firmware to date.
The built-in video player ("4K") is pretty good and allows playback of 1080p & 3D video flawlessly.
So Good things:
- Smooth 1080p video playback
- 3D SBS video playback (HDMI 1.4 support)
- 150 mbps Wireless
- Bluetooth 4.0
- exFAT support
- BT Air mouse support
- HDMI output support for 1080p24
- No HDMI audio pass-through (at least I can't work out how to)
- HDMI video controller limited to 2160P output (HDMI 1.4 limit?) even though device can decode 4k video
- BT Airmouse key repeat is annoying
- 720p kernel
