PiicoDev OLED Breakouts

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?

Hi Claire,

Welcome to the forum :slight_smile: Pullup resistors are on the board, so no additional parts are needed. The schematic from the product page is shown below:


Thanks for the clarification
