Key Features - Quectel EG91 Series Hardware Design

With a compact profile of 29.0mm ×25.0mm ×2.3mm, EG91 can meet almost all requirements for M2M
applications such as automotive, smart metering, tracking system, security, router, wireless POS, mobile
computing device, PDA phone, tablet PC, etc.
EG91 is an SMD type module which can be embedded into applications through its 106 LGA pads.
EG91 is integrated with internet service protocols like TCP, UDP and PPP. Extended AT commands have
been developed for customers to use these internet service protocols easily.
