https://devzone.nordicsemi.com/f/nordic-q-a/108874/nrf52833-pin-configurationHello Devzone, I&#39;m using a nRF52833DK right now, and it uses 73 pins for SOC. If I want to go to 40 pins, I&#39;m having trouble figuring out which pins are for peripherals like spi and i2c. We can choose the nrf52833DK board directly in build configurationsen-USTelligent Community 13Mon, 04 Mar 2024 12:46:48 GMThttps://devzone.nordicsemi.com/thread/472017?ContentTypeID=1Mon, 04 Mar 2024 12:46:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e507c0c3-82ba-4026-bcb0-630db24fe0a9Simonr<p>Hi</p> <p><span>If SPIM0, SPIM1, or SPIM2 is used with 8 Mbps data rate, the recommended GPIOs for the clock signal (SCK) are P1.09, P0.04, and P0.31. These should all be available on the QFN 40 package of nRF52833. This is stated in the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52833%2Fpin.html">nRF52833 PS pin assignments</a> section for reference.</span></p> <p><span>Best regards,</span></p> <p><span>Simon</span></p><div style="clear:both;"></div>
