Second, the introduction of

This module provides power for 5--26V. When the power supply is less than 9V, 2A dc is required. The other power outlet is 3.5-4.2v, suitable for lithium battery power supply. Computer debugging USB- TTL can be. Suitable for portable. Two sets of antenna SMA port, give GPS and GSM antenna. Two sets of IPX ports, conveniently embedded in the aluminum box to lead out the antenna. 1 channel TTL serial port, GPS and GSM functions can be switched arbitrarily. Can achieve GPS positioning, SMS, data and other functions, standby in 80MAaverage. Can provide sleep data, power consumption in about 10MA. With voice and microphone interface. Belongs to 4 frequency and is available worldwide.

1 channel GPS antenna interface, SMA interface, can be connected to the active antenna (default), can also be connected to the passive antenna
1 channel GSM antenna interface, SMA interface
1 channel bluetooth antenna interface, SMA interface
All the way to voice interface, all the way to MAC interface
An efficient LDO power supply with an input voltage of 5-26v. Note that when the input voltage is less than 9V, please ensure that the power supply can provide 2A current. 3.5-4.2v input (suitable for lithium battery power supply)
