Hi all,

I need to add an I2C sensor to my BLE project.

After checking schematic and board I think I need to sold 2 pull-up resistor R38 and R39.

Could someone confirm.

Hi MarcioMontenegro,

For a lightly loaded bus, it is possible to use

the pull-up resistors built into each PSoC I/O pin instead of

external resistors.

To avoid destroying the output driver of any of the parts,

never use both external and internal resistors – use one or

the other.
