SSD1306 OLED 屏幕模塊配備 0.9 英寸迷你單色屏，128×32 分辨率，白光像素點。擁有極高的對比度，顯示清晰極易辨識。OLED 僅使用樹莓派的 I2C 和電源引腳，無需獨立供電，即插即用。

接線

屏幕模塊的 VCC 接樹莓派 Pico 的 3V3 引腳
屏幕模塊的 GND 接樹莓派 Pico 的 GND 引腳
屏幕模塊的 SDA 引腳接樹莓派 Pico 的 GP14 引腳
屏幕模塊的 SCL 引腳接樹莓派 Pico 的 SCL 引腳

下面是示例代碼，在屏幕上輸出指定的信息，將代碼保存在 Pico 上，命名為 main.py。

import machine
import ssd1306
 
i2c = machine.I2C(1, sda=machine.Pin(14), scl=machine.Pin(15), freq=400_000)
print("I2C device: " + str(i2c.scan()[0]))
oled = ssd1306.SSD1306_I2C(128, 64, i2c)
 
oled.text("PICO LAB", 0, 0)
oled.hline(0, 10, 128, 1)
oled.text("Hello World!", 0, 26)
oled.hline(0, 48, 128, 1)
oled.text("PICO.NXEZ.COM", 0, 52)
oled.show()

顯示效果如圖。
