1Introduction
In this document you can find the information on how to use the evaluation board (EVB) to develop and
test Quectel L80, L80-R, L86, and LC86L modules.
1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any terminal incorporating Quectel L80, L80-R, L86 and LC86L modules. Manufacturers of the
terminal should distribute the following safety information to users and operating personnel and include
these guidelines into all manuals supplied with the product. Otherwise, Quectel assumes no liability for
customers’ failure to comply with these precautions.
Ensure that the use of the product conforms to the national safety and
environmental regulations, and is allowed to be used in the country and in the
required environment.
Keep away from explosive and flammable materials. The use of electronic
products in extreme power supply conditions and locations with potentially
explosive atmospheres may cause fire and explosion hazards.
The product must be powered by a stable voltage source. Additionally, the wiring
must conform to security and fire prevention regulations.
Proper ESD handling procedures must be applied throughout the mounting,
handling and operation of any application that incorporates the module to avoid
ESD damages.

1. 1) The antenna connector is invalid for the L80-R module, as the module does not support an external
antenna.
2. 2) The L80-R does not support active antenna detection interface, so the D307 (AADET_N) is invalid for
this module as well. Additionally, D305 and D306 are not supported by any of the applicable modules.
3. 3) The L80 and L80-R modules do not support the FORCE_ON interface, so the FORCE_ON button is
invalid for those modules.
