If you've been diggin' our monochome OLEDs but need something bigger,
this display will delight you. These displays are 2.3" diagonal, and
very readable due to the high contrast of an OLED display. This
display is made of 128x32 individual blue 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 graphic display for its crispness!
The driver chip, SSD1305 can communicate in three ways: 8-bit, I2C or
SPI. Personally we think SPI is the way to go, only 4 or 5 wires are
required and its very fast. The OLED itself requires a 3.3V power
supply and 3.3V logic levels for communication. We include a
breadboard-friendly level shifter that can convert 3V or 5V down to
3V, so it can be used with 5V-logic devices like Arduino.
The power requirements depend a little on how much of the display is
lit but on average the display uses about 50mA from the 3.3V supply.
Built into the OLED driver is a simple switch-cap charge pump that
turns 3.3V into a high voltage drive for the OLEDs.
Each order comes with one assembled OLED module with a nice bezel and
4 mounting holes. The display is 3V logic & power so we include a
HC4050 level shifter. We also toss in a 220uF capacitor, as we noticed
an Arduino may need a little more capacitance on the 3.3V power supply
for this big display! This display does not come with header attached
but we do toss in a stick of header you can solder on. Also, the
display may come in 8-bit mode. You can change modes from 8-bit to SPI
or I2C with a little soldering
Getting started is easy! 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 512 bytes of RAM since the display must
be buffered. The library can print text, bitmaps, pixels, rectangles,
circles and lines. It uses 512 bytes of RAM since it needs to buffer
the entire display but its very fast! The code is simple to adapt to
any other microcontroller.
