Description
Miniature Monochrome 128x32 I2C OLED graphic display 1" Diagonal#931 These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x32 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! The

These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x32 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!
The driver chip SSD1306, communicates via I2C only. 3 pins are required to communicate with the chip in the OLED display, two of which are I2C data/clock pins.
The OLED and driver require a 3.3V power supply and 3.3V logic levels for communication. To make it easier for our customers to use, we've added a 3.3v regulator and level shifter on board! This makes it compatible with any 5V microcontroller, such as the Arduino.
The power requirements depend a little on how much of the display is lit but on average the display uses about 20mA from the 3.3V supply. Built into the OLED driver is a simple switch-cap charge pump that turns 3.3v-5v into a high voltage drive for the OLEDs, making it one of the easiest ways to get an OLED into your project!
Of course, we wouldn't leave you with a datasheet and a "good luck": 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.
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 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.

Well made & sturdy
Size: 6.5x10ft, Color: Red
I have it in the umbrella stand however I haven’t used it yet as it hasn’t been sunny where I live.
Once I begin to use it, I’ll update this review.

Horrible quality
Size: 6.5x10ft, Color: Red
Horrible quality. The crank didn't work. The umbrella just flopped open. Once it did I cranked it, but it was cranking in wrong direction. Umbrella sat totally lopsided. The overall quality of this umbrella including the canopy is junk. Looks cheap. Returning!!

Peacock Blue
Size: 6.5x10ft, Color: Lake Blue
Not out yet because of weather, but it looks good, unusual point that some of the spokes according to the directions need to be put on yourself, but at least this way they not bent in box. Note when I bought it - it used the color Lake Blue but the picture was a Peacock Blue - I took the chance and it is a Peacock Blue- I would not call it Lake at all or sky or any of those colors. It worked out for me as it matches perfectly with my Peacock Blue cushions and other umbrellas, It defintiely seems like it is sturdy and the size looks as it should, it has a nice weight as i did open it in house to take a look, the material has a slight sheen which makes it appear a little different than my others, but not something most people would notice.
