BPI-M2 zero VS Raspberry pi Zero W

Banana Pi BPI-P2 Zero with Allwinner H2+ chip

BPI-4.0 OEM&ODM Successful case H3 for Network security information analysis instrument

The Banana Pi M2 Zero is an ultra compact single board computer which measures only 65mm*30mm. Its external interfaces are the same as the Raspberry Pi Zero W, and it will fit almost all cases and accessories for the Zero W. It uses the quad-core Cortex A7 Allwinner H3/H2+processor, with 512MB RAM. It's ideal for light-weight systems and space-limited applications. Like other members of the Banana Pi family, it supports both Linux and Android operating systems.

for Allwinner H2+ chip is EOL, so BPI-M2 Zero will use H3 chip defaults. but image for H2+ also support H3, so all image is same. support H2+ and H3 chip.
