1. The BPI-M2 quad-core single-board computer for Banana Pi is developed with Allwinner R40/V40 chip. Support onboard wifi and bluetooth, support SATA interface, can directly to hard disk. There is an SD card socket on the board, which can boot the system from the SD card2. For Banana PI BPI-M2 has strong compatibility, can run android system, Debian linux, , for system and Allwinner Tinalinux system3. For Banana PI BPI-M2 : Allwinner R40/V40 quad-core processor, 1GB LPDDR3 memory, Gigabit Ethernet port, 4USB interface, running Android5.1 smoothly.4. The size of the for Banana PI BPI-M2 is exactly the as the for 3, and the shell of the for 3 can be used directly.
