G80 Dev Board

Just checking does the G80 Development board require 2.2K pull resistors for the open drain I2C SDA & SCL data lines or are they in-built?

schematic here → http://old.ghielectronics.com/downloads/schematic/G80_Dev_Board_SCH.pdf shows I2C has R10 and R11 pulling them up. Check if they’re populated on the board, and if so, nothing to do :slight_smile:


Thanks brett appreciated, forgot there was a circuit!
