1.

Overview
The BCM20730 is a Bluetooth Human Interface Device (HID) Module base on Broadcom BCM20730 Bluetooth controller. It is integrated with PCB antenna, serial EEPROM, Crystal, and also components for the built-in switching regulators to reduce the external BOM cost. The BCM20730 Module has been designed to provide low power, low cost, and robust communications for applications operating in the globally available 2.4GHz unlicensed ISM band. It is fully compliant with Bluetooth Radio Specification 3.0.
