+### Here are some peculiarities of the different boards
+
+*   Wemos® TTGO T-Beam V1
+
+When adding a 0,96" OLED display direct to the board you have to be careful becouse thre are two different pinout versions. 
+For direct mount you need this Pinout -> 'VCC - GND - SCL - SDA'
+For example (https://www.amazon.de/dp/B07RXSKPBX) 
+The other display works too but you have to change VCC and GND.
+A direct mount is not possible to the board is not possible without damage the display!
