1 Introduction

0.96inch 128x64 OLED
  • NanoHat OLED is a small and cute monochrome OLED module with low power consumption. It is 0.96". Its resolution is 128 x 64. It communicates with a master device with I2C.
  • The NanoHat OLED module has the same form factor as FriendlyElec's NanoPi NEO. It can be stacked on a NanoPi NEO.
  • It has three onboard programmable user buttons, a 2.0mm pitch 4-Pin I2C connector.

Only GND and 5V on the 12-Pin land are connected and the rest pins are open. For more details on the 12-Pin connector refer to NanoPi NEO/Air/NEO2's wiki site.

3 Hardware Setup

Currently only the NanoPi NEO, NEO2 and NanoPi NEO Air work with this module. The NanoHat OLED module has the same form factor as FriendlyElec's NanoPi NEO. It can be stacked on a NanoPi NEO/NEO2/Air. Here is a hardware setup:

4 Install Software

To make a master device work with a NanoHat OLED you need to install a customized ROM on that master device. FriendlyElec names these image files with "xxx-OLED-xxx". For the NanoPi NEO/Air/NEO2 you need to download and run an image whose name is like "xxx-OLED-xxx". There are some code samples for NanoHat OLED. You can get these samples by running the following commands under Ubuntu core:

git clone https://github.com/friendlyarm/NanoHatOLED.git
cd NanoHatOLED
sudo -H ./install.sh


5 Run Code Samples

After the code samples are installed they will automatically run on system reboot and display date and time
Here are the definitions of the NanoHat OLED's three user buttons:
K1 -> Show date & time;
K2 -> Show master device's system status: IP address, CPU usage, RAM, CPU temperature and etc;
K3 -> Shutdown. After this button is pressed system will not be shut down immediately but will pop up a Yes/No dialog. Pressing K1 switches between Yes and No, and pressing K2 is to confirm the selection.
