In this article we look at a 1.3inch OLED Display Module For the Raspberry Pi Pico from waveshare, it measures 64×128 Pixels, it uses SPI/I2C Interface.
Here is what it looks like
It is a 1.3″ OLED Display Module which uses a SH1107 Driver and has a SPI or I2C bus option.
The board also has 2 buttons that the user can use for their needs – User key 0 and 1 in the pinout below.
Specifications
Operating Voltage:3.3V
Communication Interface: 4-Wire SPI, I2C
Display Panel: OLED
Driver: SH1107
Resolution: 64×128 pixels
Raspberry Pi Pico C/C++ and MicroPython demo code examples are available to help you get started from the link at the bottom.
