●Introduction
■The Thunderboard EFR32BG22 (OPN: SLTB010A) has been designed to inspire customers to make battery operated IoT devices with the Silicon Labs EFR32BG22 Wireless Gecko System-on-Chip. The highlights of the board include four different environmental sensors and stereo PDM microphones accessible to the EFR32BG22 wireless MCU. The peripherals have been grouped into power domains that can be turned on and off by the application code as needed.
■Programming the Thunderboard EFR32BG22 is easily done using a USB Micro-B cable and the on-board J-Link debugger. A USB virtual COM port provides a serial connection to the target application, and the Packet Trace Interface (PTI) offers invaluable debug information about transmitted and received packets in wireless links. Included on the board is an 8 Mbit serial flash that can be used for Over-The-Air (OTA) firmware upgrade, or as a general purpose non-volatile memory. The Thunderboard EFR32BG22 is supported in Simplicity Studio™, and a Board Support Package (BSP) is provided to give application developers a flying start.
■Energy profiling and advanced wireless network analysis and debugging tools are available through the provided Mini Simplicity Connector using an external Silicon Labs debugger.
■Connecting external hardware to the Thunderboard EFR32BG22 can be done using the 20 breakout pads which present peripherals from the EFR32BG22 Wireless Gecko such as I2C, SPI, UART and GPIOs. The breakout pads follow the same pinout as the expansion headers (EXP) on other Silicon Labs Starter Kits.
