Quectel M66
Ultra-small Quad-band
GSM/GPRS Module
Build a Smarter World
M66 is an ultra-small quad-band GSM/GRPS module using LCC castellaon packaging on the market. Based on the latest 2G
chipset, it has the opmal performance in SMS & Data transmission and audio service even in harsh environment. The ultra-
compact 15.8mm × 17.7mm × 2.3mm prole makes it a perfect plaorm for size sensive applicaons.
M66 adopts surface mount technology, making it an ideal soluon for durable and rugged designs. The low prole and small
size of LCC package makes sure M66 can be easily embedded into size-constrained applicaons, and provides reliable
connecvity with applicaons. This kind of package is ideally suited for large-scale manufacturing which has strict require-
ments for cost and eciency.
The compact form factor, low power consumpon and extended temperature make M66 a best choice for M2M applicaons
such as wearable devices, automove, industrial PDA, personal tracking, wireless POS, smart metering, telemacs, and more.
