Silicon Laboratory Inc. EFR32FG1P133F256GM48-C0 | Demoboard BRD4251B

Description

The EFR32FG family of Wireless SoCs deliver a high performance,low energy wireless solution integrated into a small formfactor package.The EFR32 Flex Gecko Radio Boards provide a development platform (together with the Wireless Starter Kit Mainboard) for the SiliconLabs EFR32 Flex Gecko Wireless System on Chips and serve as reference designs for the matching networks of the RF interfaces.The BRD4251D Radio Board supports dual-band operation with its integrated sub-GHz ISM band and 2.4 GHz band transceivers. Thesub-GHz section is designed to the operate in the European ETSI 169.4-169.475 MHz band with an external whip antenna, the 2.4 GHzsection is designed to operate at the 2400-2483.5 MHz band with the on-board printed antenna. The matching networks are optimizedto 19.5 dBm output power.To develop and/or evaluate the EFR32 Flex Gecko the BRD4251D Radio Board can be connected to the Wireless Starter Kit Mainboardto get access to display, buttons and additional features from Expansion Boards and also to evaluate the performance of the RFinterfaces.
