https://devzone.nordicsemi.com/f/nordic-q-a/54301/i2c-bus-capacitance-to-define-external-pull-upHi, I would like to know the I2C bus capacitance for the nrf52840. Do someone have the information please ? My slave components are compliant for 400Khz and VDD is 3.3V. I put 2k2 pull up on SDA and SCL lines. Thank in advance for your help, Besten-USTelligent Community 13Wed, 13 Nov 2019 08:24:07 GMThttps://devzone.nordicsemi.com/thread/219820?ContentTypeID=1Wed, 13 Nov 2019 08:24:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6c526365-6f6a-4587-b331-0cb03e4d4208ketiljo<p>The pin (GPIO) capacitance is ~4 pF</p><div style="clear:both;"></div>
