I try to connect a 0.96" OLED to the “airrohr v1.4”.  
Some OLED’s connected to the airrohr show nothing and others only “snow” (nothing readable)  
I tested with connector J6 and J7 - without success.  
Connected are on the NodeMCU V3 (or V3.4): SDS011 - BME280 - DNMS.

@jsturm our firmware only supports I2C OLED displays. And these are connected in the same manner than the BME280, D3 to SDA and D4 to SCL. Yes, the BME280 and the OLED can use the same pins. I2C is a serial bus.

I found the reason why I had no display.  
I replaced a faulty P82B715PN and now it works
