## Description

The compact OLED display module for displaying text, icons and system information in embedded projects, mounts quickly as a shield on boards such as Raspberry Pi Pico, Pico W, RP2040 or Jetson Nano. The 2.23 inch screen with 128x32 resolution offers high contrast and low power consumption, uses the SSD1305 driver and supports SPI communication by default or I2C by hardware reconfiguration.
Compact OLED display module, ideal for displaying text, simple graphics or system information on development boards such as Arduino, Raspberry Pi Pico, Raspberry Pi Pico W, WH or Jetson Nano. The screen is 2.23 inches in size and has a resolution of 128x32 pixels, offering high contrast and low power consumption. The module is designed as a shield, which facilitates direct connection and quick integration into embedded projects.
The module can operate in both I2C and SPI mode, the change being made by moving the resistors on the module.

Use:
It mounts directly on the Raspberry Pi Pico or other compatible boards and can be easily controlled through software libraries available in MicroPython or the Raspberry Pi SDK.
The module uses the SPI interface by default, configured in hardware by 0R resistors (jumpers) connecting the BS1 pin to GND and BS2 to NC (not connected). This configuration is achieved by soldering the resistors to the upper pads.
To change the communication mode to I2C, it is necessary to reconfigure the resistors on the board, according to the instructions below:
