UNO Dock V2.0 for NanoPi NEO
Contents
1 Introduction
- 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.

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. Tools -> Processor ->ATmega328
3. Tools -> Port ->COM2(the device name you find in your PC)
- Step 4: click on "upload".
After Arduino IDE shows uploading success you can start playing with your UNO Dock!
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。
