As shown, the primary interface to the TigoAir 2 SOM is through its footprint and from an internal\external antenna or from the footprint RF pad, for wireless communication. The footprint interface provides power, serial communication, analog inputs and output and other connectivity options. All information presented in this document is confidential and for internal use only. Copyright 2019, CoreTigo Ltd. Page 6 of 26 TigoAir 2 SOM 2 System Overview 2.1 SoC The TigoAir 2 SOM SOM uses Silabs EFR32FG13P232F512GM48-D SoC for stack, IOLW radio communication, external interfaces and application development. The EFR32FG13P232F512GM48-D is 32bit ARM Cortex-M4 Core MCU, 512KB Flash, 64KB RAM, analog IOs, serial communication interfaces and GPIOs. For software development, CoreTigo supplies an SDK package that includes: IOLW stack, MCU peripherals usage example, and an example application. Additional information can be found in EFR32FG13P232F512GM48-D datasheet 2.2 Antenna The TigoAir 2 SOM supports three options for antenna selection, by different assembly options:

1. On-board U.FL[4] connector for external antenna 2. On-board ceramic chip antenna: Johansons 2450AT18D0100[2]

3. RF PAD to host board via the footprint All information presented in this document is confidential and for internal use only. Copyright 2019, CoreTigo Ltd. Page 7 of 26 TigoAir 2 SOM 2.3 TigoAir 2 SOM Interface TigoAir 2 SOM interfaces are through its footprint on the bottom side of the board. It contains a total of 45 pads:

- Power 9 pads (2 VDD, 7 GND)

- Signal 35 pads (Communication buses, digital IOs, analog inputs, programming, and debug)

- RF 1 pad (RF transmission to the host board) The SoC pin-out configuration allows for operation of most pins as GPIOs/Analog inputs/Analog outputs when they are not used with any specific functionality (example: PB13 that is connected to pad 16 can be used as defined - USART1 RX function, or alternatively it can be set to be GPIO).
