ISP140501 Beacon

Bluetooth Low Energy Wireless Beacon Detection


Features | Applications | Block Diagram | Main Specifications | Dev Zone


ISP140501 is an autonomous low-power device for wireless detection and transmission. Overall size of the device is 33 x 33 x 8.7 mm. It has been developed to explore the full range of development possibilities for beacons using Bluetooth Smart technology. They allow indoor positioning, letting your phone know that you are in range of a beacon. As the “beacon” name suggests, they transmit packets of data in regular intervals, and this data can be then picked up by devices like smartphones.
