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! ## Features - 0.91 INCH OLED Display: Resolution is 128*32,Very Clear,Black background with blue text display. - IIC(I2C) interface: Only 4 PIN( VCC, GND, SCL, SDA), Simpler than SPI interface Screen, you can leave more ports for connecting other sensors. - Sample Code and Technical Support: You can drive this display through the u8glib library.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little OLED display *by V***O on March 22, 2019* If you are looking for a small, bright, 2-line OLED display to use in your Arduino, etc. projects, you have found it.

Strongly recommended! ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - DSD TECH 2 PCS IIC OLED Display 0.91 Inch for Arduino ARM - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - HiLetgo 2pcs DHT22/AM2302 Digital Temperature And Humidity Sensor Module Temperature Humidity Monitor Sensor Replace SHT11 SHT15 for Arduino Electronic Practice DIY --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/91148259-dsd-tech-2-pcs-iic-oled-display-0-91-inch](https://www.desertcart.pt/products/91148259-dsd-tech-2-pcs-iic-oled-display-0-91-inch) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-22*
