#77905 This is really to simple so I wonder why I never have seen this before.

NodeMCU boards and ESP32 devellopment boards do not fit a breadboard as they are to wide.

Two solutions:
1 cut your breadbaord in half and use both halves
2 cut the power rail on one side of a breadboard and use two breadboards.

#91277 I understand. These breadboards are pretty difficult to work with. Not only fitting an ESP32 or simolar board is difficult, these breadboards are not broad enough to expose all the GPIOs on both the sides.

I have solved this problem in this video. Do have a look. It might be helpful
