2.23 Inch OLED Display HAT for Raspberry Pi, 128×32 Pixels, SSD1305

This OLED display module is a HAT expansion board for Raspberry Pi with a screen diagonal of 2.23 inches and a resolution of 128×32 pixels. It utilizes the integrated SSD1305 driver chip and communicates via SPI or I2C interfaces. The interface selection is done by reconfiguring an onboard resistor, with SPI being active by default.

The display is fully compatible with the 40-pin GPIO expansion header of the Raspberry Pi and supports not only the entire Raspberry Pi series but also platforms like Jetson Nano, Arduino, and STM32 through exposed control pins.

Due to its compact format, the display is particularly suitable for implementing simple user interfaces or status indicators. Development materials and example code for multiple platforms are available.
