Banana Pi BPI-M2 Berry
Software
On the software side of things, the sample board came with Raspbian pre-installed (apparently prepared in Germany) on an SD Card. Connecting the board to a console is easy because, contrary to an RPi, it has an accessible debug port to which you can connect a serial-to-USB converter. The full boot log is available at the end of this article.According to the BPi GitBook, images for Android and Ubuntu should be available, but for me the links returned '404 - Not Found'. This will hopefully be fixed once the board is released to the public. For the M2 Ultra a special Linux, Tina-IoT by Allwinner is available too, but how to adapt it for the M2 Berry is no mentioned. Maybe it runs out of the box, maybe it doesn't?
is wider than the one on the RPi (right)
Conclusion
The banana pi BPI-M2 Berry is targeted at RPi users. Being introduced after the RPi3 one would expect it to have similar performances as an RPi3, but in reality we are dealing with an RPi2 v1.0 with Wi-Fi, Bluetooth 4.0 and SATA. Since the Berry is priced similarly to the RPi3, the SATA interface may very well be the only reason to prefer this board over a real RPi (3 or 2).The BPi M2 Berry did not fit in my RPi test case due to the size of the SD Card slot, but since the sample board is from a pre-series run, this may be corrected before release to the public. A bit of cutting will fix this problem, more problematic though may be the incompatible LCD and camera connectors. They were probably kept for compatibility with other BPi boards, but they break the RPi-compatible promess.
