EFR32FG Flex Gecko 2.4GHz/434MHz Dual-Band Radio Board

The Silicon Lab EF32 Flex Gecko SLWRB4251B Radio Board supports dual-band thanks to the integrated sub-GHz ISM band and the 2.4 GHz band transceivers. The sub-GHz section is designed to work in the European ETSI 433.05-434.79 MHz band with an external whip antenna. The 2.4 GHz section operates in the 2400-2483.5 MHz band with the on-board printed Inverted-F antenna.
The matching networks are optimised for +10 dBm output power.
The radio board can be attached to the Wireless Starter Kit Mainboard BRD4001A to offer a development platform for the EFR32 Flex Gecko Wireless System-on-Chips. Alternatively, the starter kit is available in our offer.
