Radicom Research’s RB730 and 730SD (Shielded) are Bluetooth modules featuring Human Interface Device (HID) support. Based on Broadcom BCM20730 Bluetooth chipset, the modules integrate with PCB antennas, serial EEPROMs, crystals and components for built-in switching regulators to reduce external BOM costs.
The RB730 and RB730SD Bluetooth modules integrate the entire profiles, applications, and Bluetooth protocol stack. They are fully compliant with the Bluetooth SIG specifications for human interface devices. The RB730 and RB730SD are fully compliant with version 3.0 Bluetooth specification including enhanced power control (Unicast Connectionless Data), which is essential to mouse and keyboard applications of personal computers.
By integrating major components within today’s mice and keyboards, the RB730 and RB730SD can interface directly to optical mice, ball encoders and keyboard scan matrixes which help reduce BOM costs in manufacturing those PC peripherals.
The RB730 and RB730SD provide superior performance in the presence of interference from 802.11 (Wi-Fi) wireless devices and other 2.4GHz radios. The RB730 and RB730SD are built-in with internal EEPROM. OEM specific parameters and settings can be easily loaded into these modules.
The RB730 is a surface mount PCB module with on-board antenna built-in.
