Peripherals
6. Peripherals
The starter kit has a set of peripherals that showcase some of the features of the EFR32.
Be aware that most EFR32 I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when
using the breakout pads for your application.
6.1 Push Buttons and LEDs
The kit has two user push buttons marked PB0 and PB1. They are connected directly to the EFR32, and are debounced by RC filters
with a time constant of 1 ms. The buttons are connected to pins PF6 and PF7.
The kit also features two yellow LEDs marked LED0 and LED1, that are controlled by GPIO pins on the EFR32. The LEDs are connec-
ted to pins PF4 and PF5 in an active-high configuration.
