Product Description

1.1. Overview

The document contains L76, L76-L, L76-L(L) modules. You can choose the dedicated module based on
your requirement.
The modules support multiple global positioning and navigation systems: BeiDou, GPS, Galileo,
GLONASS and QZSS. These modules also support SBAS (including WAAS, EGNOS, MSAS and
GAGAN) and AGNSS functions. The default constellation configuration is GPS + GLONASS.
Key features:
⚫
All the modules are single-band, multi-constellation GNSS devices and feature high-performance
and high reliability positioning engines. The modules facilitate a fast and precise GNSS positioning
capability.
⚫
All the modules support serial UART communication interfaces. I2C is only supported by L76-L
module.
⚫
Embedded with many advanced power saving modes including GLP, AlwaysLocate™, Standby and
Backup, the modules feature low-power consumption in different scenes.
⚫
All the modules are featured with EASY™ technology, one kind of AGNSS. Capable of collecting and
processing all internal aiding information like GPS time, ephemeris, last position, etc., the modules
deliver a very short Time to First Fix (TTFF) in either hot or warm start.
⚫
The embedded flash memory provides the capacity for storing user-specific configurations and future
firmware updates.
⚫
L76 and L76-L, the standard I/O voltage variants, have 2.7–2.9 V I/O voltage; L76-L(L), the low I/O
voltage variant has a 1.7–1.9 V I/O voltage.
⚫
The three module variants are of a SMD form factor measuring 10.1 mm x 9.7 mm x 2.5 mm and can
be embedded in your application using the 18 LCC pins.
⚫
The three modules are EU ROHS Directive compliant.
