4.2.1 Expansion Header Pin-out
The pin-routing on the EFR32 is very flexible, so most peripherals can be routed to any pin. However, many pins are shared between
the Expansion Header and other functions on the Wireless STK Mainboard. Table 4.1 Expansion Header Pinout on page 6 includes
an overview of the mainboard features that share pins with the Expansion Header.
