ST STEVAL-BLUEPIRV1, User Manual, Page: 2 / 17

1 Overview
The STEVAL-BLUEPIRV1 evaluation board comes ready-to-use and working out-of-the-box. It provides all the
functionality expected from a wireless motion detector.
Some LEDs show the Bluetooth
®
Low Energy status and motion detection. Then, using the STBLESensor app,
you can visualize the battery status and signal strength as well as the motion indication.
The Bluetooth
®
Low Energy module is separable to allow the designer to use the analog part only.
The supply and output reading are available on a separate header and all the analog signals are placed on a
testing point.
The
STEVAL-BLUEPIRV1 features:
• BlueNRG-M2SA module for Bluetooth
®
Low Energy communication
• Connectivity with the STBLESensor app
• Analog signal conditioning based on the TSU102 operational amplifier
• Window comparator based on the TS883 open-drain comparator
• Power management based on the STLQ020 ultra-low quiescent LDO
• Powered by a single CR2032 coin cell battery
