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.
