+## OLED Display
+
+In this section, we'll learn how to connect an OLED display module to the Raspberry Pi Pico 2.
+
+We'll create simple projects like displaying text and an image (display Ferris 🦀 image) on the OLED. We'll use the I2C protocol to connect the OLED display to the Pico.
+
+### Hardware Requirements
+
+For this project, you'll need:
+- An OLED display (0.96 Inch I2C/IIC 4-Pin, 128x64 resolution, SSD1306 chip)
+- A breadboard
+- Jumper wires
+
+<img style="display: block; margin: auto;width:500px" alt="pico2" src="../images/oled-ssd1306.jpg"/>
+
+## New crates
+In addition to the usual crate like `rp-hal`, we will be using these new crates necessary for the project.
+
+- [`ssd1306`](https://github.com/rust-embedded-community/ssd1306): a driver for the SSD1306 OLED display, supporting both I2C and 4-wire SPI.
+- [`embedded-graphics`](https://github.com/embedded-graphics/embedded-graphics): a 2D graphics library tailored for memory-constrained embedded devices, enabling text and graphic rendering.
+- [`tinybmp`](https://github.com/embedded-graphics/tinybmp): a lightweight BMP parser for embedded, no-std environments. We'll use this to directly load `.bmp` images with the `embedded-graphics` crate, avoiding the need for raw image data.
