https://devzone.nordicsemi.com/f/nordic-q-a/66707/nrf24l01-connectionHello, My sck frequency will be 5Mhz. Accordingly, nrf24l01 + mcu and SPI parameters as Rpull = 10kohm and Cload = 50pF How should I connect pins and which pins ( (ce,csn,sck,mosi,miso,irq)) do I need to connect according to the SPI time parameteren-USTelligent Community 13Thu, 08 Oct 2020 14:54:29 GMThttps://devzone.nordicsemi.com/thread/273832?ContentTypeID=1Thu, 08 Oct 2020 14:54:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fa7b4d30-e9ee-417d-9331-64033d79673fKenneth<p>The marking looks good, but to be sure you would likely need to ship it here for analysis.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/273652?ContentTypeID=1Thu, 08 Oct 2020 08:12:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:66b82ad8-73da-4a31-a655-5125aa49b25dazmi42<p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/7230.NRF2.jpeg" /><img class="align-right" style="float:right;" alt="Do you think my nrf is original? the person I bought says it's original.

This is not something you really need to consider if you plan to use 5MHz, just connect the pins as shown in the reference layout to your MCU (do not add the load and pull-up resistor shown in figure 26).</p><div style="clear:both;"></div>
