With a compact profile of 29.0mm × 32.0mm × 2.4mm, EC25 can meet almost all requirements for M2M
applications such as automotive, metering, tracking system, security, router, wireless POS, mobile
computing device, PDA phone, tablet PC, etc.
EC25 is an SMD type module which can be embedded into applications through its 144-pin pads,
including 80 LCC signal pads and 64 LGA pads.
