This section gives a short introduction to the blocks of the BRD4100A Radio Board.

3.2 Radio Board Block Diagram

The block diagram of the EFR32BG Radio Board is shown in the figure below.

3.3 Radio Board Block Description

3.3.1 Wireless MCU

The BRD4100A EFR32 Blue Gecko Radio Board incorporates an EFR32BG1P232F256GM48 Wireless System on Chip featuring 32-bitCortex-M4 with FPU core, 256 kB of flash memory and 32 kB of RAM and a 2.4 GHz band transceiver with output power up to 10.5dBm. For additional information on the EFR32BG1P232F256GM48, refer to the EFR32BG1 Data Sheet.

3.3.2 LF Crystal Oscillator (LFXO)

The BRD4100A Radio Board has a 32.768 kHz crystal mounted.

3.3.3 HF Crystal Oscillator (HFXO)

The BRD4100A Radio Board has a 38.4 MHz crystal mounted.

3.3.4 Matching Network for 2.4 GHz

The BRD4100A Radio Board incorporates a 2.4 GHz matching network which connects the 2.4 GHz TRX pin of the EFR32BG1 to theone on-board printed Inverted-F antenna. The component values were optimized for the 2.4 GHz band RF performace and current consumptionwith 10.5 dBm output power.For detailed description of the matching network, see Chapter 4.2.1 Description of the 2.4 GHz RF Matching.

3.3.5 Inverted-F Antenna

The BRD4100A Radio Board includes a printed Inverted-F antenna (IFA) tuned to have close to 50 Ohm impedance at the 2.4 GHz

band.

For detailed description of the antenna see Chapter 4.5 Inverted-F Antenna.

3.3.6 UFL Connector

To be able to perform conducted measurements, Silicon Labs added an UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.

Note: By default the output of the matching network is connected to the printed Inverted-F antenna by a series component. It can be connected to the UFL connector as well through a series 0 Ohm resistor which is not mounted by default. For conducted measurements through the UFL connector the series component to the antenna should be removed and the 0 Ohm resistor should be mounted (see Chapter 4.2 Schematic of the RF Matching Network for further details).

3.3.7 Radio Board Connectors

Two dual-row, 0.05” pitch polarized connectors make up the EFR32BG Radio Board interface to the Wireless Starter Kit Mainboard. For more information on the pin mapping between the EFR32BG1P232F256GM48 and the Radio Board Connector, refer to Chapter 2.2 Radio Board Connector Pin Associations.

     【闸机】

　　闸机，是一种通道阻挡装置(通道管理设备)，用于管理人流并规范行人出入，主要应用于地铁闸机系统、收费检票闸机系统。其最基本最核心的功能是实现一次只通过一人，可用于各种收费、门禁场合的入口通道处。

　　中国最早应用闸机是80年代期间，用于地铁项目中。闸机作为“自动售检票系统AFC”中的“自动检票机”的主要设备，也是目前国人对闸机最早和最广泛的理解。90年代后期，闸机才渐渐出现在普通民用和商用场合，包括写字楼、商场超市、景区乃至高端小区等。

　　需要指出的是，闸机和检票机不是完全相同的概念。检票机包括自动检票机和便携式检票机，自动检票机是闸机结合票务系统的一种具体应用。闸机的范围更广，只要是用于管理人流出入且能满足一次只通行一人的设备都可以视为广义的闸机。

　　闸机的应用场合分室内外，室内外环境不一样，适用的闸机也不一样。

　　室内所有种类的闸机均适用。

　　室外使用是完全露天或有遮挡物，但都需考虑日晒、雨淋、沙尘、超高温、超低温、昼夜温差大等户外恶劣环境，室外闸机需要能抵挡这些 天气问题，适用的闸机包括专门针对室外使用设计的户外摆闸、户外翼闸、半自动三辊闸、半自动全高转闸。

　　户外闸机基本需求：防水防尘等级IP65、耐高温、耐低温、抗阳光干扰，户外摆闸、户外翼闸、半自动三辊闸、半自动全高转闸通过特殊定制都能实现。

　　户外闸机高级需求：人车共用、抗暴力撞闸。在某些场合，行人可能骑自行车、推婴儿车、坐轮椅等，户外翼闸、半自动三辊闸、半自动全高转闸这三者不能满足这个需求，人车共用户外摆闸可以满足，另外闸机会有被自行车撞击的现象，需具备抗暴力撞闸功能。
