Review: Great little OLED display - If you are looking for a small, bright, 2-line OLED display to use in your Arduino, etc. projects, you have found it. This 0.91" OLED display from DSD Tech is well made, has only 4 pins to connect (GRD, VCC, SCL and SDA), and is very easy to incorporate into your Arduino, etc. projects. There is a library in the Arduino repo for this (and other DSD Tech displays), and DSD Tech has a sketch on their website that you can download, enter the info you want to show on the two-line display, then upload it to your Arduino. This is my first time using a DSD Tech product, but with the look, performance and low price of this 0.91" OLED display, I'll be looking to them in the future for more of this and other products they offer. I highly recommend this product.
Review: Cheap, useful, great view - I've used this as part of my smart car project, connected to Arduino through I2C. It works beautifully! It offers a crisp easy to read display, even under the Texas Sun! You can find ready made libraries for Arduino too for several different boards, including original arduino and ESP32 boards. For the price, I would not mind having a few of these in my drawer just for future projects. Beware though, this is a "small" screen (which is why bought this one in the first place) so don't expect a large screen. But let me tell you this, it fits really nicely inside my dashboard button cluster! This thing can fit into very small places! Strongly recommended!

## Questions & Answers

**Q: What are the i2c addresses? can they be changed?  how many can you run on 1 i2c buss?**
A: According to the datasheet for the OLED display driver, the slave address can either be 0b0111100 (0x3C), or 0b0111101 (0x3D). 
From documentation:
"... “SA0” bit provides an extension bit for the slave address. Either “0111100” or “0111101”, can be 
selected as the slave address of SSD1306."

**Q: can picaxe microcontroller drive this model?**
A: It is theoretically possible. But DSD TECH does not provide demo code. Please buy with caution.

**Q: Do I need to use i2c pull up resistors?**
A: Didn't need them on the displays I purchased.

**Q: Can i change the i2c address of this device by changing resistors on the pcb? usually these parts are available. is there a schematic?**
A: No

### ⭐⭐⭐⭐⭐ High refresh rate, great product
*by A***R on September 2, 2020*

Although the documentation is not immediate, there are directions to the git library which is easy to work with. In fact, there is even a wiki for this library. One key feature for my project was the refresh rate (i.e. characters change quickly without previously one fading slowly) and can push up to about 1200 wpm. However, the display is small but this was advertised as such.
