Description
VX-18-B is a Viaanix BLE Beacon. VX-18-B is a single-mode Bluetooth low energy product for the
Bluetooth Smart market. VX-18-B can be used where space is limited. VX-18-B enables ultra low-power
connectivity and basic data transfer for applications previously limited by the power consumption, size
constraints and complexity of other wireless standards. VX-18-B provides everything required to create a
Bluetooth low energy product with RF, baseband, MCU, qualified Bluetooth v4.1 specification stack, 3-
axis accelerometer, and customer application running on a single compact board.
Applications
● Fridge/Freezer temperature monitoring
● Usage through vibration
● Security door open/close
● Asset Tracking
