+
+      The nRF54L15 PDK does not have the Arduino-compatible header.
+      The connection layout may differ depending on the revision of your PDK.
+      GPIO assignments are recommended by the Nordic Semiconductor. 
+
+      The nRF54L15 PDK operates on a lower voltage level (1.8V). 
+      The Semtech Shield is compatible with this voltage and can be safely provided to the pin marked as 3.3V.
+      Due to the lower voltage, the Semtech radio cannot achieve the full transmit power, and it will reach a plateau at 15 dBm gain even when a higher value is configured.
+      The specification of the Semtech module describes that it is possible to provide a separate, higher voltage source for radio while maintaining the lower voltage for communication. 
+      However, the recommended shield does not support this configuration.

+         .. tab:: PDK revision v0.2.1
+
+            The v0.2.1 PDK revision does not require any hardware modification, but the buttons are reused to connect the Semtech SX126X shield.
+            Pressing the buttons while working with the Semtech module can lead to malfunctions and undefined behavior.
+            This issue is caused by the limitation of the v0.2.1 PDK revision. 
+            It is possible to assign different pins for the radio shield, but you might need to disable some of the PDK's functions, or modify connections by cutting or soldering PDK bridges.

+            To use the suggested pins, disable **UART0** (not used by Sidewalk samples) through the `Board Configurator`_ tool in the nRF Connect for Desktop.
+            This step is required for the shield to work as some pins are connected to **UART0** by default.
