LoNet-迷你 GSM/GPRS/GPS 突破

We have an updated product: LoNet 808 - Mini GSM/GPRS + GPS Breakout

For customers who had ordered the old version will get the new one for replace.

LoNet is a GSM and GPS two-in-one function module. It is based on the latest GSM/GPS module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation.

It features ultra-low power consumption in sleep mode and integrated with charging circuit for Li-Ion batteries, that make it get a super long standby time and convenient for projects that use rechargeable Li-Ion battery. It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver charnels. Besides, it also supports A-GPS that available for indoor localization.

The module is controlled by AT command via UART and supports 3.3V and 5V logical level. It comes with a mini GPS and GSM antenna, but not includes Li-Po battery. In addition, to use this module, you still need an unlock SIM-Card supporting GPRS service.
