Hello, I designed a pcb in Kicad which is based on the esp32 pico d4 and feautures a sh1106 based 1,3 inch oled display over i2c. I desoldered the display from its board and soldered it on to my pcb. The schematic I used is from hier: https://www.waveshare.com/w/upload/e/e3/1.3inch-SH1106-OLED.pdf. I made a test pcb for the display which worked. Then I recreated the shematic on my pcb with the esp. When the display is not soldered on the board, everything works fine, inlcuding the i2c scann. When the display is soldered on to the board, the esp crashes when it starts to scan. I found that i forget to connect display pin 12 to ground, what I fixed with solder, but it doesent work anyway. Can someone look at the schematic please. Thanks for your help. Carl
