EVQ3369-R-01A Evaluation Board

Hello,

I have a EVQ3369-R-01A evaluation board which uses the MPQ3369GR-AEC1-Z LED driver.

I am trying to interface with the MPQ3369 chip using an FPGA through the I2C interface.
On the evaluation board SDA line is not pulled up as R19 and R2 are not connected. I am assuming that I need to solder resistors here to pull-up the SDA line.

Can you tell me what resistor values I should use here?

Best,
Dante.

Hi @dsajjadi,

I have generally seen a 4.7k or 10k pull-up on the I2C lines.

Thank you
