Introduction
This module is 5-12V power supply, when the power supply is less than 9V, 2A DC is required. The other power supply port is
3.5-4.2V, suitable for lithium battery power supply. The computer can debug USB-TTL. Suitable for portable. Two sets of antenna
SMA ports, GPS and GSM antennas are provided. Two sets of IPX ports are convenient to be embedded in the aluminum box to
lead out the antenna. 1 TTL serial port, GPS and GSM functions can be switched at will. It can realize GPS positioning, SMS,
data and other functions, standby at 80MA{average value}. Sleep data can be provided, and power consumption is about 10MA.
With voice and microphone interface. It belongs to 4 channels and is available worldwide.
SIM808_mini board uses high-performance industrial grade GSM/GPRS quad-band chip, and integrates GPS and
Bluetooth functions: SIM808, working frequency band: GSM850/EGSM900/DCS1800/PCS1900MHz. Can realize telephone
voice, SMS (short message, MMS), GPRS data transmission function (support transparent transmission mode, domain
name resolution and IP mode), also has DTMF decoding (can identify the other party's keys), GPS positioning, the
upgraded version also supports Bluetooth 3.0 . The hardware is upgraded on the basis of the design of the hardware
manual, using a low-ripple LDO power supply, and the SIM card uses a gold-plated deck for better sensitivity. Module application areas: remote communication equipment such as remote monitoring, remote smart meter reading,
smart home and vehicle equipment

Onboard resources
