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.

2.1 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 module can be stacked on a NanoPi NEO/Air/NEO2. Here is a hardware setup:

3.2 Install BakeBit Software

• Step 1 - SSH to a master device(NanoPi NEO/Air/NEO2) via ssh and download the BakeBit code from github:

cd  ~
git clone https://github.com/friendlyarm/BakeBit.git

• Step 2 - Install BakeBit software packages by running the following commands:

cd BakeBit/Script
chmod +x install.sh
./install.sh

• Step 3 - Reboot:

reboot

• Step 4 - Test UNO Dock V2.0 for NanoPi NEO:

Connect a BakeBit LED module to a UNO Dock V2.0 for NanoPi NEO by linking the LED module's SIG pin to the Dock's D3 and run the following command:

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

If the LED blinks it means the UNO Dock V2.0 for NanoPi NEO works!

4 Setup Arduino on UNO Dock V2.0 for NanoPi NEO

• Step 1:use a jumper in place of "UNO-UART", connect the Dock to a PC host with a USB cable and power the Dock with a 12V DC power source
• Step 2:check the device name in your PC's device manager. In our test case it was "COM2".
  

• Step 3:download Arduino IDE Arduino IDE Download Link

Setup development environment:
1. Tools -> Board ->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。
