Amount of SDRAM is 2GB DDR3 and storage for OS and data is 8 GB eMMC (option 16/32/64 GB) or microSDXC card (up to 256 GB). As GPU is used dual-core Mali 400 MP2 - support 1080P 4K video.
CSI interface for camera and DSI interface display is ready on the board.
You can use 10/100/1000 Mb ethernet (?through USB?), 3x USB2.0 a 1x USB2.0 OTG.
3.5 mm jack stereo konektor is used for audio output.
BPI-M64 can be powered 5V/2A or 3.7V Li-Ion battery.

So... somebody will release some Arduino board every week.
Today, I would like to introduce new Arduino board called Fireboard.
Combine Arduino, Dual-core Cortex-M3, low power wifi module and price $15 (one Fireboard + 8GB TF card) can be very good idea.
This board contains also audio module.
Designers maked support code in Arduino IDE. If you don't like programming, you can use graphical tool for creating of code - FireBlock.
The microprocessor is Rockchip RKNanoD....

Wireless Oscilloscope Probe - Aeroscope very insteresting project on
