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 Hardware Spec

2.1 Connector Pin Description

Here is a pin description for the UNO Dock V2.0 for NanoPi NEO's connectors:

• UNO Dock V2.0 for NanoPi NEO Connector Pin Description:

3 Connect UNO Dock V2.0 for NanoPi NEO to NanoPi NEO/Air/NEO2

3.1 Connect to NanoPi NEO/Air/NEO2

Currently the applicable boards are FriendlyElec's NanoPi NEO/Air/NEO2. The NanoPi NEO2 doesn't work with Bakebit
The module can be stacked on a NanoPi NEO/Air/NEO2. Here is a hardware setup:

3.2 Install BakeBit Software

• 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.
  

• 第三步，下载安装Arduino IDE软件，Arduino IDE下载地址

请如下配置环境：
1、选择工具->开发板->Arduino Nano


2、选择工具->处理器->ATmega328


3、选择工具->端口->COM2(选择对应的计算机端口)

• 第四步，点击上传按钮，测试环境。

如果Arduino IDE软件提示“上传成功”，恭喜你，可以充分发挥你的想象，开始你的UNO Dock之旅了！

5 注意

使用Arduino IDE软件下载Arduino程序后，会覆盖UNO Dock V2.0 for NanoPi NEO单片机中的固件，如果此时回到NanoPi NEO/Air/NEO2上使用UNO Dock V2.0 for NanoPi NEO，需要先给UNO Dock V2.0 for NanoPi NEO下载固件，固件源码已上传到github，直接使用Arduino IDE上传即可。
