2. GENERAL PRODUCT DESCRIPTION

Overview

The ME910G1 module is a CATM/ NBIoT communication product which allows integrators

to plan on availability for even the longest lifecycle applications, highly recommended for

new designs specified for worldwide coverage.

The ME910G1-WWV product is fully voice capable, the digital audio interface make it

suitable for applications such as voice enabled alarm panels, mHealth patient monitors

and specialty phones such as those for the elderly or sensory-impaired.

The ME910G1 operates with 1.8 V GPIOs, minimizing power consumption and making it

even more ideal for application with battery powered and wearable device.
