https://devzone.nordicsemi.com/f/nordic-q-a/69155/low-frequency-i-o-signal-usageHi, We are using nRF52840 in our design. the pin p0.10 is marked as LOW-FREQUENCY I/O (up to 10Khz) according to your recommended usage. Our software is design to generate a digital output of 8Mhz at p0.10, it works very well for now. Can you please explainen-USTelligent Community 13Sun, 06 Dec 2020 16:55:42 GMThttps://devzone.nordicsemi.com/thread/283426?ContentTypeID=1Sun, 06 Dec 2020 16:55:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:424ee0de-1871-4f15-8bb6-69be89a09752Dmitry<p>Hi,</p> <p>P0.10 is located near RF antenna pin, using it for high-frequency IO may affect radio performance, see <a href="https://devzone.nordicsemi.com/f/nordic-q-a/36367/using-gpios-marked-as-standard-drive-low-frequency-for-spi-on-nrf52840">this discussion</a>.</p><div style="clear:both;"></div>
