Feature:
Support GPS, BD, GLO, LBS base station positioning, all-round positioning.
Equipped with RTC backup battery, support hot start and warm start, the positioning speed is greatly enhanced.
Positioning data supports GPS independent serial port acquisition and configuration, more options, more convenient.
The positioning data also supports the GSM serial port, which is obtained and configured through AT commands, which is faster and simpler.
Adding various kinds of single-chip programs, greatly helping the rapid development of single-chip.
Advantage:
Rich interfaces, common planning of common interfaces, and integrated headphone jack, leading to save space with a pin
The power supply has an enable control pin, which can control the power switch, and can realize remote unmanned control.
Both the main serial port and the GPS serial port integrate level matching circuits, and the compatibility is very stable.
With 2 status indicators, the module status is clear and easy.
Antenna 50R impedance matching, GSM signal measured up to 31 full grid under strong environment
Support base station positioning, normal positioning when GPS signal is poor
With the same quality and the same chip, we have the lowest price and high cost performance.
Package includes:
1 x SIM868 development board module
1 x SMA head GPS Beidou dual-mode antenna
1 x IPEX to SMA cable
1 x GSM / LTE antenna
RTC backup power supply: the device is powered to the RTC after power off.
GPS power control pin: It is used to control whether the GPS part inside the module has electricity to achieve the purpose of power saving.
GSM antenna interface: connect to GSMGPRS antenna, which is IPX-MINI type antenna interface.
DC-DC module: MSP series high-reliability power chip is used, and the power enable pin is led out.
Main serial port and power pins: The serial port is compatible with 3.3V and 5V controllers and supports mainstream MCUs such as 51STM32.
Active GPS antenna: The antenna interface of the GPS antenna is IPX-MINI.
MICROS SIM card holder: In-line SIM card holder, when the card is inserted, the SIM card slot faces outward
