https://devzone.nordicsemi.com/f/nordic-q-a/27772/twi-p0-30-scl-and-p0-31-sda-i2c-with-nrf52832Hi, I&#39;d just start developping with the nRF52832 and I would like to communicate with a sensor using the I2C protocol. Has I am a stranger with the nordic uC, I would like to know if I can choose any pin available on the nRF52832.

What&#39;s the limit ? 10kHz 100kHz 1Mb ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/109526?ContentTypeID=1Sat, 02 Dec 2017 00:03:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6e0b1412-90d2-47f7-80be-9efd83b558deRK<p>Yes you can choose any pin you want. Please check the documentation which recommends avoiding high speed communications on the pins next to the antenna pins and note that two pins are used by default for the NFC and need to be disabled and the chip reset before you can use them for other purposes. However, with those caveats aside, you can use any pin you like.</p><div style="clear:both;"></div>
