Wireless Starter Kit Mainboards (BRD4001A) Development and evaluation of the BGM113 Bluetooth module is possible by attaching the BRD4301A board to the Wireless Starter Kit (WSTK) Mainboard. This gives access to the WSTK display, buttons and additional features offered by using the available Ex- pansion Boards. silabs.com Smart. Connected. Energy-friendly. Rev. 1.00 BRD4301A Reference Manual BRD4301A Radio Board Description 1. BRD4301A Radio Board Description The BRD4301A Radio Board contains the BGM113 Blue Gecko Bluetooth Module soldered onto a carrier board with two connectors. The connectors on the carrier board are used for attaching the BRD4301A on to a Silicon Labs Wireless Starter Kit Main-board BRD4001A and together these two boards and the software in the BGM113 Module make up the Blue Gecko Bluetooth Module Wire- less Starter Kit. The BGM113 Bluetooth 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 BGM113 Module is ideal for applications requiring Bluetooth connectivity such as used in connected home, health and fitness, wearables and point-of-sale terminal applications. The BGM113 includes an energy friendly ARM Cortex M4 MCU. A major benefit offered by the BGM113 is that no RF or Bluetooth protocol expertise is required. The BGM113 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 BGM113 Module Block Diagram The BGM113 Module block diagram is illustrated in the figure below.
