DESIGN CONCERNS
This section provides design information, such as powering the evaluation board, sensor interface settings, ad hoc mode,
and restoring factory settings.
Powering the Module
You can power the RN-174 evaluation board from the RS-232 header, the UART interface, or the power connector. You
should only provide power on one of the three power connectors.
Figure 3 shows the jumper settings for the different power modes.

If powered from the RS-232 header (J3), apply 5 to 16 V DC power on pin 9 and ground to pin 5 of the RS-232
header.
If powered from the UART header (J8), apply 3.3 V DC power on pin 1 and ground on pin 2 of the UART
interface.
If powered from the power connector (J7), apply 4 to 16 V DC power, depending upon the jumper configuration
of the power select jumpers (J4).
