D1 Mini Shield – OLED 64×48

Last Updated on 15. October 2026 by SuffocationLink status: OK

Diese Zusatzplatine bietet zum Display alles, was zur Ansteuerung eines Oled Displays notwendig ist.

For the D1 mini ESP8266 and ESP32, go here:

Facts

  • Oled Display 64×48 Pixel

D1 Mini Shield – Oled 64×48 – Pins und Adressen

If two displays are to be controlled, the I2C address can be changed to 0x3D by re-soldering a jumper. (See the back of the PCB)

Test programme

I have used the test program from the library:

Source code ssd1306_64x48_i2c.ino (GitHubLink status: OK)

/*********************************************************************
This is an example for our Monochrome OLEDs based on SSD1306 drivers

  Pick one up today in the adafruit shop!
  ------> http://www.adafruit.com/category/63_98

This example is for a 64x48 size display using I2C to communicate
3 pins are required to interface (2 I2C and one reset)
