Serial OLED

Serial OLED is a small adapter board for cheap 128×64 0,96″ OLED i2c display module and it can be used as a serial console for microcontroller projects with 3.3V logic level. One of the four microswitches is hardwired as the reset for the Serial OLED board. Other three switches are connected to the digital pins of the on-board microcontroller. The additional FTDI connector (host) can be used to program the Serial OLED board itself.

There are two popular models of cheap 0,9″ OLED displays based on SSD1306 driver IC available on the ebay. They are slightly different size (27x27mm and 27x28mm) and the supply polarity is different. This adapter board fits both modules and the supply polarity for the OLED module can be set by the solder-jumpers.

Features

  • Compatible with 27x27mm and 27x28mm 0,9″ i2c OLED modules
  • OLED module supply voltage polarity set by solder-jumpers
  • Onboard Atmega-328p microcontroller
  • Logic level: 3.3V
  • Supply voltage: 5V
  • Reset switch
  • User assignable switches: 3
