## Overview
BG77xA-GL is a 5G-ready ultra-compact LPWA module compliant with 3GPP E-UTRA Release 13/ 14 specification. The module supports LTE Cat M1 and LTE Cat NB1/ NB2 bands and integrated SIM (iSIM). Besides, it features ultra-low power consumption implemented by integrated RAM and flash, which help reduce current consumption to rather low levels in various modes, including PSM, e-I-DRX, etc. It is further integrated with a GNSS engine that supports GPS and GLONASS systems. BG77xA-GL comes in two variants: BG770A-GL and BG773A-GL.
BG77xA-GL boasts a comprehensive hardware-based security feature—Integrated Security Elements (ISE). With an ultra-compact SMT form factor of 14.9 mm × 12.9 mm × 1.9 mm and a high integration level, the module enables integrators and developers to design applications easily leveraging its low power consumption and compact structure design. The BG77xA-GL’s advanced LGA package allows for fully automated manufacturing required for large-scale applications.
A rich set of Internet protocols, industry-standard interfaces and abundant functionalities extend the applicability of the module to a wide range of M2M applications, such as wireless POS, smart metering, tracking, wearable devices, and many more.
