1 Introduction

The NanoPi A64 is a new board of high performance with low cost designed by FriendlyElec. It uses Allwinner’s A64 quad-core SoC(ARM Cortex-A53). FriendlyElec has made a UbuntuCore and a UbuntuMATE image files for it.

The NanoPi A64 is a small board with comprehensive interfaces, ports and features. It has Ethernet, IR receiver, Video/Audio input and output. It has onboard AXP803 PMU and WiFi. It takes power input from its MicroUSB port. It has MIPI-DSI and DVP interfaces, GPIO pin-header compatible with Raspberry Pi and a serial debug port.

说明

1. SYS_3.3V: 电源输出, 实际输出为3.1V
2. VDD_5V: 5V电源输入/输出。输入范围：4.7～5.6V, 可通过MicroUSB接口供电, 也可通过40pin排针或Debug Port上的VDD_5V供电. VDD_5V与MicroUSB的VBUS直接相连.
3. 全部信号引脚均为3.3V电平(实际是3.1V, 兼容3.3V)，输出电流为5mA,可以带动小负荷模块，io都不能带负载
