connections (PWR, TX, RX and GND) to create a

wireless data connection. Additionally, the analog

sensor inputs can be used to interface a variety of

sensors such as temperature, audio, motion and

acceleration. The ability to go into deep sleep mode

and automatically scan and associate to an AP when

awake makes the RN-171 suitable for roaming

applications. The RN-171 also includes a built in

HTML client to automatically post serial uart data or

sensor data to a web server.

Designs that include the boost regulator will provide good supply to the flash even when the battery voltage drops close to 1.8V board containing RN-171 does not include the boost regulator, it SHOULD include a 2.7V undervoltage reset circuit to prevent the module from accessing flash when supply voltage falls below 2.7V. ...
