WaveShare 2.23inch OLED Display Module 128×32 Pico

SKU CH-BZFR-PTDWP

2.23 inch OLED display module with 128×32 pixel resolution, SSD1305 driver, SPI and I2C interfaces, 3.3 V or 5 V operation, and Raspberry Pi Pico header

  • CPU TypeOther
  • 128×32 pixel resolution delivers crisp monochrome graphics
  • 23inch compact panel fits tight project enclosures
  • Embedded SSD1305 driver simplifies firmware integration
  • Dual SPI and I2C interfaces enable flexible wiring
  • Pico-compatible header plugs straight onto Raspberry Pi Pico boards

Raspberry Pi Pico OLED module

This 2.23inch OLED display module mounts directly on a Raspberry Pi Pico header. It provides a 128×32 pixel black-and-white panel driven by an embedded SSD1305 controller. The board accepts both 3.3V and 5V supply levels. Development resources include C/C++ and MicroPython examples.

Makers adding a tiny status screen

The module suits hobbyists who need a compact readout for sensor data, menus or debugging on a Pico board. Builders requiring colour, higher resolution or a larger viewing area should consider other display types. Projects that cannot spare the SPI or I2C pins must choose a different interface.

128×32 pixel resolution

The display shows 128 columns by 32 rows of monochrome pixels. This density fits short text lines, icons or simple graphs. Applications needing detailed graphics or multiple text lines will find the grid too small.

Questions about this item

What does the 128×32 pixel resolution mean for text and graphics on the 2.23inch screen?

The display shows 128 columns by 32 rows of black and white pixels, giving a compact area suited to status lines, sensor readouts or simple menus rather than detailed images.

How do the SPI and I2C interfaces affect data speed and wiring?

The module offers both 4-wire SPI and I2C; SPI provides faster throughput for animations while I2C uses fewer pins, letting you choose based on the Raspberry Pi Pico's available GPIO.

What physical connection does the board need to fit a Raspberry Pi Pico?

It uses the standard Raspberry Pi Pico header, so the module plugs directly onto a Pico series board without extra cables or adapters.
