LA66 LoRaWAN Module
1.1 What is LA66 LoRaWAN Module
Dragino LA66 is a small wireless LoRaWAN module that offers a very
compelling mix of long-range, low power consumption, and secure data
transmission. It is designed to facilitate developers to quickly deploy
industrial-level LoRaWAN and IoT solutions. It helps users to turn the idea
into a practical application and make the Internet of Things a reality. It is
easy to create and connect your things everywhere.
LA66 is a ready-to-use module that includes the LoRaWAN v1.0.3
protocol. The LoRaWAN stack used in LA66 is used in more than 1 million
LoRaWAN End Devices deployed world widely. This mature LoRaWAN stack greatly
reduces the risk to make stable LoRaWAN Sensors to support different LoRaWAN
servers and different countries’ standards. External MCU can use AT command to
call LA66 and start to transmit data via the LoRaWAN protocol.
Each LA66 module includes a world-unique OTAA key for LoRaWAN
registration.
Besides the support of the LoRaWAN protocol, LA66 also supports open-source
peer-to-peer LoRa Protocol for the none-LoRaWAN application.
LA66 is equipped with TCXO crystal which ensures the module can achieve
stable performance in extreme temperatures.

FCC Statement
FCC Caution:
Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
IMPORTANT NOTE:
Note: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not nstalled and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
