Little Backup Box uses luma.oled as the display driver. In principle, all displays supported by luma.oled can be controlled.

Some displays do not seem to be suitable for the Little Backup Box due to the resolution or geometry, so they are currently not supported. For others, there may be undesirable representations. Feedback is requested here, optimizations may be possible.

A Display must be configured and activated in the settings.

Display	Experience
I2C/SPI ssd1306 monochrome 128x64 pixels	Working, no problems known.
I2C/SPI ssd1306 dual color 128x64 pixels	Working but not recommended. The display works like a monochrome display, but a part in the upper area is shown in its own color. This does not correspond to lbb's display usage.
SPI ssd1331 color display	Working, no problems known. Colors are supported. Because the display is smaller (96x64 pixels vs. the 128x64 pixels of ssd1306), please select font size 10. Other settings: RGB, SPI

Image 1: Case with display
Little Backup Box supports a 128x64 dot display. This must be addressable with I2C or SPI. These devices usually will cost less than 10 €. In addition, you need jumper cables in a female-female configuration.

Your display has 4 PINS:

• GND: Ground, black in Image 2
• VCC: Power 3.3V or 5.0V, depends on your display, red in Image 2
• SCL: i2c-clock, green in Image 2
• SDA: i2c-data, blue in Image 2

At first find out the specifications of your display: VCC 3.3V or 5.0V? Your vendor should provide the information.

• unplug your Raspberry Pi
• connect Display-VCC to PIN 1 "3V3 power" or PIN 2 "5V power", depending on your displays specifications.
• connect Display-SCL to PIN 5 "GPIO 3 (SCL)"
• connect Display-SDA to PIN 3 "GPIO 2 (SDA)"
• connect Display-GND to PIN 6 "Ground" (or any other of the PINs named "Ground")

No liability is assumed for any damage caused by errors (including grossly negligent) in these instructions.

SPI has up to seven pins:

• VCC: Power 3.3V
• GND: Ground
• D0: Clock
• D1: MOSI
• RST: Reset
• DC: Data/Command
• CS: Chip Select

Please also note Figure 3 for wiring.

• unplug your Raspberry Pi
• connect Display-VCC to PIN 1 "3V3 power"
• connect Display-GND to PIN 6 "Ground" (or any other of the PINs named "Ground")
• connect Display-D0 Clock to PIN 23 GPIO 11 (SCLK)
• connect Display-D1 MOSI to PIN 19 GPIO 10 (MOSI)
• connect Display-Reset to PIN 22 GPIO 25
• connect Display-DC to PIN 18 GPIO 24
• connect Display-CS to PIN 24 GPIO 8 (CE0)
