Appendix A: Bluetooth Evaluation Board

The Roving Networks Bluetooth Evaluation

board has several interfaces for configuration

and programming. These are listed below in the

table. The board is powered by and external

5VDC power plug or through pin 9 in the DB9

connector.

The Bluetooth radio same command set and

configuration parameters are consistent across all

Roving Networks Bluetooth modules, serial

adapters and USB dongles so applications can be

developed using the evaluation board and run on

embedded Bluetooth module such as the RN-41

or RN-24.

Power Terminals

Inputs on P1 power connector can be 4.5VDC to 11.0VDC. There is internal regulation down to 3.3VDC for all

circuitry. Worst case power draw for the board is 100ma when the Bluetooth radio/modem connection is established

and transmitting. Power can be as low as 1ma to 25ma average when the Bluetooth radio/modem is not connected

depending on parameter settings.
