Whisker.io Engine™, Long Range Wireless
D6 Labs Whisker Engine
General Description
The Whisker.io Engine™ is a long-range, ultra-low power intelligent
RF module designed for battery powered IoT applications. Using the
new LoRa technology from Semtech, the module is capable of
communicating over very long distances: up to
16 kilometers
with
proper antenna elevation. The module can operate for up to 5 years
from a pair of common AA batteries. All data communications are
encrypted using 128-bit AES.
The module is available in surface and through-hole packages and is
FCC certified.
