BPI-M4-Zero User Guide

Introduction

Banana Pi BPI-M4 Zero is the successor model of M2 Zero. It has a huge improvement in performance. The SOC is upgraded to H618 and the CPU frequency is increased by 25%. The memory is upgraded to DDR4, the capacity is quadrupled, and 8G eMMC is added. It supports 5G WiFi, and the USB interface has also been upgraded to type-C.

It has same form factor and 40-pin connector as the Raspberry Pi Zero W, and it can fit most of the RPI Zero W cases and accessories.
