Need hardware reference design for the use of nRF21540 with nRF54L15

Hi Support Team

Could you provide us the hardware reference design for the use of nRF21540 with nRF54L15? Many thanks.

Hi,

We don't have any reference designs combining the nRF21540 and nRF54L15 as of now. But there is no special requirements RF wise, the two reference design can just be combined.

One thing to keep in mind is the pin selection for the nRF21540, the clock line for SPI must be on dedicated clock pins on the nRF54L15, if the P2 pins is used there are also dedicated pins for all the SPI pins. See the pin assignment section of the datasheet for more info on the dedicated clock and peripheral pins on the nRF54L15:

Best regards,
