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 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. forum.banana-pi.org/t/banana-pi-bpi-m2-zero-quad-core-singel-board-computer-with-allwinner-h2-chip-design/3532
