 ## Board configuration
 
+### UART selection
+
+By default the UART peripheral is used for the TX/RX pins, however the pinout
+is compatible with LEUART also. You can switch from UART to LEUART by compiling
+with `EFM32_USE_LEUART=1`.
+
+**Note**: LEUART is not working on the ICC-1 module.
+
 ### Clock selection
 There are several clock sources that are available for the different
 peripherals. You are advised to read [AN0004.1]
