Key Benefits
M66 is currently the smallest Quad-band GSM/GRPS module
using LCC castellation packaging on the market. Based on the
latest 2G chipset, it has the optimal performance in SMS &
Data transmission and audio service even in harsh environ-
ment. Its ultra-compact 15.8 × 17.7 × 2.3mm profile makes
M66 a perfect platform for size sensitive applications.
M66 adopts surface mounted technology, making it the ideal
solution for durable and rugged designs. And its low profile
and small size of LCC package ensure M66 easily embedded
into the low-volume applications and provide the reliable con-
nectivity with the applications. This kind of package is ideally
suited for large-scale manufacturing which has the strict re-
quirements for cost and efficiency.
Its compact form factor, low power consumption and extended
temperature make M66 the best choice for applications such
as wearable devices, automotive, industrial PDA, personal
tracking, wireless POS, smart metering, telematics and other
M2M applications.
