These displays are small, only about 1" diameter, but very readable
due to the high contrast of an OLED display. This display is made of
128x64 individual white OLED pixels, each one is turned on or off by
the controller chip. Because the display makes its own light, no
backlight is required. This reduces the power required to run the OLED
and is why the display has such high contrast; we really like this
miniature display for its crispness!
This breakout can be used with either an SPI or I2C interface -
selectable by soldering two jumpers on the back. The design is
completely 5V-ready, with an onboard regulator and built in boost
converter. It's easier than ever to connect directly to your 3V or 5V
microcontroller without needing any kind of level shifter!
We have a detailed tutorial and example code in the form of an
Arduino library for text and graphics. You'll need a microcontroller
with more than 1K of RAM since the display must be buffered.
You can download our SSD1306 OLED display Arduino library from github
which comes with example code. The library can print text, bitmaps,
pixels, rectangles, circles and lines. It uses 1K of RAM since it
needs to buffer the entire display but its very fast! The code is
simple to adapt to any other microcontroller.
* PCB: 38mm x 29mm (1.5" x 1")
* Screen: 25mm x 14mm
* Thickness: 4mm
* Weight: 8.5g
* Display current draw is completely dependent on your usage: each
OLED LED draws current when on so the more pixels you have lit, the
more current is used. They tend to draw ~20mA or so in practice but
for precise numbers you must measure the current in your usage
* This board/chip uses I2C 7-bit address between 0x3C-0x3D,
selectable with jumpers
