+ *
+ * Important:
+ * On the nRF54L15 Development Kit pins P0.00...P0.03 are
+ * connected to the debugger chip and by default connect UART0 of the
+ * debugger chip to the nRF54L15. The UART0 function (VCOM0) of the debugger
+ * chip must be disabled to allow the pins to be used as FEM control signals
+ * and FEM I2C interface. The "Board Configurator" tool (v0.3.7) being part of
+ * "nRF Connect for Desktop" bundle can be used for this purpose.
+ *
+ * On the nRF54L15 Development Kit pin P0.04 is connected also to "Button 3".
+ * Please do not press this button while the firmware nRF2240-EK containing
+ * the code with this shield is running.
