Introduction
1. Introduction
The EFR32 Wireless Gecko Radio Boards provide a development platform (together with the Wireless Starter Kit Mainboard) for the
Silicon Labs EFR32 Wireless Gecko System-in-Package modules and serve as reference designs for the matching networks of the RF
interfaces.
The BRD4207A Wireless Gecko Radio Board plugs into the Wireless Starter Kit Mainboard, which is included with the Wireless Gecko
Starter Kit and gives access to display, buttons, and additional features from Expansion Boards. With the supporting Simplicity Studio
suite of tools, developers can take advantage of graphical wireless application development for Z-Wave Long Range applications and
visual energy profiling and optimization. The board also serves as an RF reference design for applications targeting wireless operation
in the 863-876 MHz and 902-930 MHz bands with 14 dBm output power.
To develop and/or evaluate the ZGM130S, the BRD4207A Radio Board can be connected to the Wireless Starter Kit Mainboard to get
access to display, buttons, and additional features from Expansion Boards, and also to evaluate the performance of the RF interfaces.

3.3 Radio Board Block Description
3.3.1 SMA Connector
To be able to perform conducted measurements or mount external antenna for radiated measurements, range tests, etc., Silicon Labs
added an SMA connector to the radio board. The connector allows an external 50 Ohm cable or antenna to be connected during design
verification or testing.
3.3.2 Printed Antenna
The BRD4207A Radio Board includes a printed antenna tuned to have close to 50 Ohm impedance at the 863-930 MHz band.
For a detailed description of the antenna, see section 4.4 Printed Antenna.
3.3.3 Radio Board Connectors
Two dual-row, 0.05” pitch polarized connectors make up the BRD4207A Radio Board interface to the Wireless Starter Kit Mainboard.
For more information on the pin mapping between the ZGM130S037HGN2 and the connectors, refer to section 2.2 Radio Board Con-
nector Pin Associations.
