1 Introduction

UNO Dock V2.0 for NanoPi NEO
  • The UNO Dock V2.0 for NanoPi NEO is a NanoHat Hub alike extension board.
  • It is an Arduino board compatible with Arduino UNO and works with Arduino programs.
  • The UNO Dock V2.0 communicates with NanoPi NEO/Air/NEO2 with I2C. The MEGA328P on the board acts as an interface between an external module connected to the board and the NanoPi NEO/Air/NEO2 that is mounted on the board.When a NanoPi NEO/Air/NEO2 and an Arduino module are connected to the UNO DOCK users can easily access the Arduino module from the NanoPi NEO/Air/NEO2.
  • It has an onboard USB to Serial port chip which allows users to set the serial port as either Arduino serial port or NanoPi NEO/Air/NEO2's debug port with a jumper
  • It has 12V power input to 5V/2A output.
  • The two USB ports on the NanoPi NEO/Air/NEO2 are populated to the module
  • The male connectors on the NanoPi NEO/Air/NEO2 are populated to the module and a NanoHat module can be stacked on it.
  • NEO's GPIO pins are populated to the module
  • NanoPi NEO/Air/NEO2 can be directly mounted on the UNO Dock V2.0.

2 特性

  • 兼容Arduino UNO接口。
  • USB转串口。
  • 12V电压输入,板载电压转换和电源开关。
  • 支持BakeBit解决方案。
  • 两个USB扩展接口。
  • NEO接口排针,可直接堆叠连接NanoHat模块。
  • NEO GPIO排母,方便排线外接其他模块。
  • PCB尺寸(mm):112x53.3

3 如何在NanoPi NEO/Air/NEO2上使用UNO Dock V2.0 for NanoPi NEO

3.1 连接NanoPi NEO/Air/NEO2

目前支持的开发板有NanoPi NEO/Air/NEO2。NanoPi NEO2暂时不支持Bakebit
连接方法是倒扣NanoPi NEO/Air/NEO2到你的UNO Dock V2.0 for NanoPi NEO上即可,参考下图连接模块:

3.2 安装BakeBit软件包

  • 第1步 - 通过ssh,或者串口终端进入开发板的命令行,从 github 上下载BakeBit代码:
cd  ~
git clone https://github.com/friendlyarm/BakeBit.git
  • 第2步 - 使用如下命令在开发板上安装BakeBit包:
cd BakeBit/Script
chmod +x install.sh
./install.sh
  • 第3步 - 重启开发板:
reboot
  • 第4步 - 验证UNO Dock是否正常工作:

将LED配件的SIG信号用杜邦线连接到UNO Dock V2.0 for NanoPi NEO上的D3引脚,在命令行执行以下命令操作LED:

python ~/BakeBit/Software/Python/grove_led_blink.py

看到LED闪烁,恭喜你,UNO Dock V2.0 for NanoPi NEO已经为你准备好了!

4 如何在UNO Dock V2.0 for NanoPi NEO上使用Arduino

  • 第一步,将UNO Dock V2.0 for NanoPi NEO板的串口跳线帽装在UNO-UART侧,使用USB线连接电脑,使用12V直流电源给板子供电。
  • 第二步,电脑的计算机管理器查看UNO Dock板的串口号,例如本机的串口号是COM2.
