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.

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!

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".
