Overview zero with Allwinner H3 chip

BPI-M2 zero VS Raspberry pi Zero W

Banana Pi M2 Zero is an ultra compact single board computer measures only 60mm*30mm. It uses quad-core Cortex A7 allwinner H2+ processor, with 512MB RAM memory. It's ideal for light-weight systems with some space-limited applications. Like other members of Banana Pi, it supports both linux and android operating system.

mini size only 60mm*30mm, all interface same as Raspberry pi Zero W.
