Arduino OLED Display Module FAQ

Should I use an I²C or SPI OLED module with my Arduino?

I²C can share a two-wire bus with other devices. SPI requires more signal lines and may suit faster updates. Confirm the exact module's interface and pin configuration against the board and the update speed you need.

Can I use the same library for SH1106, SSD1305 and SSD1309 OLED modules?

Check that the library explicitly supports the module's controller, interface and pixel dimensions. Similar-looking modules can require different initialization or addressing. Use the controller named in the exact product specification.

Can I connect a 5 V Arduino directly to the OLED module?

Check the module's supply voltage and signal voltage limits separately. A regulator on the OLED board does not establish that all signal pins tolerate 5 V. Follow the module and host pinouts and use level shifting if required.

What should I check if my I²C OLED stays blank?

With power off, check the pin order, ground and supply. Confirm the host's SDA and SCL pins, then check the module address, controller and resolution in your software configuration.

How do I check whether a PCB OLED module fits my enclosure?

Compare the board outline, mounting hole positions, header height and active area with your enclosure. Send us your board layout and visible opening if you want us to check a module and its connector clearance.

Specifications, sample availability, minimum order quantity and lead time are confirmed for each model and order.
