Introduction
M35/M35F is the world’s quad-band GSM / GPRS module, the size is only 19.9 x 23.6 x 2.65mm.
With ultra-small size, ultra-low power and wide operating temperature range, the M35 is ideal for M2M applications for automotive, industrial and PDA, personal tracking, wireless POS, smart metering and other M2M applications Perfect GSM / GPRS SMS, data transmission and voice services.
The M35/M35F is available in LCC packages and enables rapid production of modules via standard SMT equipment, providing customers with highly reliable connectivity, especially for automated, large-scale, low-cost, modern production methods.
With the built-in remote remote upgrade technology (QuecFOTATM), M35 can achieve remote upgrade and maintenance.
