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.

  • GPIO Pin Description
Pin# Name Linux gpio Pin# Name Linux gpio
1 SYS_3.3V 2 VDD_5V
3 I2C0_SDA 4 VDD_5V
5 I2C0_SCL 6 GND
7 NC 8 NC
9 GND 10 NC
11 K1 0 12 NC
13 K2 2 14 GND
15 K3 3 16 NC
17 SYS_3.3V 18 NC
19 NC 20 GND
21 NC 22 NC
23 NC 24 NC

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

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


The script downloads and installs the samples and some utilities. Mainland Chinese users can download them faster by changing the source:
Open the "/etc/apt/sources.list" file, copy the following lines to replace the existing contents:

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

Or edit(or create) the "$HOME/.pip/pip.conf" file and set Python's pip to a mainland Chinese source. Here is what pip.conf looks like:

[global]
trusted-host =  mirrors.aliyun.com
index-url = http://mirrors.aliyun.com/pypi/simple

After these commands are executed run "sudo apt-get update" to update software packages and then run "./install.sh" to begin installation.

5 演示程序的操作说明

演示程序在安装后会在开机时自动运行,并默认显示 日期与时间 画面。
NanoHat OLED配件上的三个按键功能如下:
K1 -> 显示日期时间;
K2 -> 显示开发板的运行状态,例如 IP地址, 负载, 存储状态,CPU温度等信息;
K3 -> 关机操作,并不会立即关机,而是先弹出询问画面,在询问画面的状态下,用 K1 切换 Yes和No选项,K2进行确认;
