RB8762 Designer’s Guide_draft v04 3 Introduction Thank you for choosing Radicom RB8762 Module. We are committed to providing you quality service and technical support. The RB8762 modules are designed to meet OEM’s needs of embedding low power, wireless data connectivity to their products. The RB8762 family offers a quick and simple solution for wireless Bluetooth communications. The Radicom RB8762 module is designed to meet the emerging market for Bluetooth 4.2 applications. These embedded Bluetooth 4.2 modules integrate entire profiles, applications, and Bluetooth protocol stack, so no external processor is needed. The module contains an internal S-Flash so custom parameters and settings can be easily loaded into these modules. The RB8762 can be factory configured for other Bluetooth cost-effective and power-efficient wireless consumer products such as watches, medical sensors, mice, TV remote controls and fitness trainers. Contact Radicom for help to add the BLE Data Protocol functionality to your 4.0 Bluetooth device or for help in determining which Bluetooth Module is the best fit for your particular Bluetooth application. The RB8762 family modules can be powered with standard 3V3 low power. In lowest mode it consumes only uA level power and will wake up in few hundred microseconds. The RB8762 family provides superior performance in the presence of interference from 802.11 (WiFi) wireless devices and other 2.4GHz radios. The RB8762 modules support quick connections and data transfers allowing an application to establish a Bluetooth connection within a few milliseconds for short communication bursts before quickly disconnecting the Bluetooth connection to save power. It takes much less time to make a connection than conventional Bluetooth wireless technology and consumes approximately only 1/20th of the power of Bluetooth Basic Rate. The RB8762 is available in surface mount (SMD) or through-hole (Dip) hardware designs. The RB8762 module is the surface mount model. The RB8762 can also mounted on a conversion board to create the RB8762HM model for serial through-hole designs.
RB8762 Designer’s Guide_draft v04 4RB8762EVK and BLE Functionality Radicom provides RB8762EVK Development Kits to provide a quick platform for testing and evaluating the RB8762 and RB8762HM Bluetooth modules. The kit includes two RB8762 modules mounted on the RB8762HM Dip Module. Each RB8762HM is installed into a RB8762MB evaluation board. One of the RB8762HM is configured to operate in BLE Data Protocol Master mode. The other RB8762HM is configured to operate in BLE Data Protocol Slave mode. The RB8762MB boards have an RS232 Serial Port Connector that allows the user to immediately connect to any standard serial port to evaluate the Bluetooth modules. The RB8762 modules are defaulted to use the BLE Data Protocol. For BLE Data Protocol operation, you need one Radicom Master and one Radicom Slave module. The Slave Model RB8762-S advertises or broadcasts the Bluetooth signal. The Master Model RB8762-M will scan for Bluetooth signals and then request a Bluetooth connection. The RB8762-S Slave can then accept the connection for BLE Data transfers. The RB8762-S Slave can also operate with remote devices that also support the BLE Data Protocol.

Always use RoHS compliant Parts and materials. • Suggestions for Layout: 1. Do not place Power circuit, X’tal, Inductor, etc near RF area. 2. The bigger Antenna clearance area, the better. The Antenna itself needs to stay away from any circuit or component at least 3mm. Antenna clearance area means Top and Bottom both required to be cleared. 3. Do not use metal materials on design where near Antenna area. For example, battery snaps, USB connector, iron case, etc. These guidelines are for design reference; real performance still depends on actual design.
