# SSD1306
|
|
|
|
|
|
|
|
|
|
Some changes made possible to use SSD1306 (instead of NOKIA5110 display).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
You can use same PCB. You only have to connect GND (SSD:GND), VCC (SSD:VCC), D/C (SSD:SDA) and SCE (SSD:SCL)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
On other PCB-layouts, PIN wemos:D1 need connected to SSD:SCL and wemos:D2 has to be connected to SSD:SDA.
|
|
|
|
|
much fun.
