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.
