Key Features - Quectel EC21 Series Hardware Design

NOTES
1)
1. GNSS function is optional.
2)
2. EC21 series module (EC21-E, EC21-A, EC21-V, EC21-AUT, EC21-AU, EC21-AUV, EC21-AUTL,
EC21-J, EC21-CT and EC21-KL) includes Data-only and Telematics versions. Data-only version
does not support voice function, while Telematics version supports it.
3)
3. B2 band on EC21-AU module does not support Rx-diversity.
4. Y = supported (including LTE and WCDMA). N = Not supported.
With a compact profile of 32.0mm × 29.0mm × 2.4mm, EC21 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.
EC21 is an SMD type module which can be embedded into applications through its 144-pin pads,
including 80 LCC signal pads and 64 other pads.
