I added some connectors according to what I usually use:
I2C (also pull ups)
SPI (with an extra pin for devices such as nrf24,...
Oled shield based on 2.54" display and ESP32. The display is used by **QG-2864KSWNG01** based on the **SPD0301 **controller (similar to SSD1306). ESP32 "Fire Bittle" is used as the base board.
