I am working on designing my own PCB that will include a Xiao RP2040 and a PiicoDev OLED.
I want to solder the OLED to the board via the 2.54mm breakouts. I know for i2c we have pull up resistors between:
SCL and 3V3
SDA and 3V3
I note that these are included on the PiicoDev OLED board.
I looked at the KiCAD files, but just wanted to get clarification. When using the breakouts to connect to my PCB do I need to add pull up resistors to my PCB or are the pull up resistors on the Piicodev OLED board already connected to the breakouts?
