Description:
The Waveshare 128x32, 2.23-inch OLED Display HAT for Raspberry Pi. This display utilizes an SSD1305 driver and supports both SPI and I2C interfaces, with SPI as the default (switchable to I2C via soldering). It directly connects to the Raspberry Pi's 40-pin header, making it an excellent, compact solution for adding a display interface.
