Help with Display Schematic

Other Hardware 3rd Party Boards

Hi:
I am using an SH1106 display and the breakout board has the following schematic:
SH1106
The breakout board has a jumper for I2C or SPI. I am planning on integrating this display on my own pcb and am trying to understand if I need all all of the circuitry that is on the breakout board. The final design will be SPI and have a +3.3V supply.

  1. The table in the figure shows R6, R7, and R8 are for I2C. R6 and R7 look like pullups for D0 and D1 which I believe are the data lines for I2C. For SPI D0 is SCLK and D1 is MOSI. Do I still need the pullups for SPI? I currently have them in my design and it works, but If I can remove them, that would be better.
  2. What is the 662K Voltage regulator for? The supply voltage for this design is the 3.3V from an esp32. Is this voltage regulator necessary or a nice to have?

Any input is appreciated!

Hi, @markbeeman
Put some header sockets on your PCB and plug it in, otherwise you will need the ribbon socket.

Keep it simple.
The breakout board even has mounting holes.

Voltage regulator for 3.3V if you are using a 5V board, probably not necessary for an ESP32 though.
