LinkIt MT2502A Module -Scale for IoT solution
Description of product
LinkIt MT2502A Module is a low-cost and low-power consumption IoT SiP module. The module is an operating deisgned for Wearables and Internet of Things(IoT)devices that can connect to other smart devices or directly to cloud applications and services. It integrates voice-band,audio-band,base-band analog front-end and full-featured power management unit. With its embedded support for GPRS/GSM, this highly integrated SoC design avoids the need for multiple chips, meaning smaller devices and reduced costs for device creators, as well as eliminating the need for compatibility tests. This module is complemented by Wi-Fi and GNSS chips, offering high performance and low power consumption to devices with more sophisticated communication or location acquisition requirements.With LinkIt MT2502A Module, it’s easier and cheaper for device manufacturers to produce desirable, functional wearable products.Features:
