M12 is a Dual-band GSM/GPRS wireless module in LCC type. It is pin-to-pin compatible with the M10 quadband module. M12 can be embedded in customer’s applications, offering good reliability and robustness.

Featuring an industry-standard interface and extremely low power consumption, M12 delivers GSM/GPRS 900/1800MHz performance for Data, SMS, Fax and Voice in a small form factor. M12 can fit into almost all M2M applications, including VTS, Smart Metering, Wireless POS, Security, etc.

M12 supports an  important remote upgrade technology which named QuecFOTA.  With the unique Quectel protocol, the new firmware of M12  will be perfectly updated by MCU via UART, and this can greatly solve the worries for M2M applications.

As a part of Quectel’s corporate policy of environmental protection, all products comply to the RoHS (Restriction of Hazardous Substances) directive of the European Union (EU Directive 2002/95/EG).
