Rev. 0.1 UG121: BRD4300A User s Guide BRD4300A Radio Board Description 1. BRD4300A Radio Board Description The BRD4300A Radio Board contains the BGM111 Blue Gecko Bluetooth Smart Module soldered onto a carrier board with two con- nectors. The connectors on the carrier board are used for attaching the BRD4300A on to a Silicon Labs Wireless Starter Kit Mainboard BRD4001A and together these two boards and the software in the BGM111 Module make up the Blue Gecko Bluetooth Smart Module Wireless Starter Kit. The BGM111 Bluetooth Smart module and the software are designed to help developers accelerate time to market with end-product design projects. This versatile plug-and-play Bluetooth solution also reduces development costs and minimizes compliance risks. The BGM111 Module is ideal for applications requiring Bluetooth Smart connectivity such as used in connected home, health and fitness, wearables and point-of-sale terminal applications. The BGM111 includes an energy friendly ARM Cortex M4 MCU. A major benefit offered by the BGM111 is that no RF or Bluetooth protocol expertise is required. The BGM111 can be used as a periph- eral along with an external host MCU or applications may be embedded into the built-in MCU using the Bluegiga BGScript scripting language. Complete standalone solutions may thus be created with minimal need for external components. 1.1 BGM111 Module Block Diagram The BGM111 Module block diagram is illustrated in the figure below.
