1、 Brief introduction of unv-sim868 development board
Unv-sim868 development board adopts a module of simcom company, which has superior performance and small size. On board micro SIM card holder, reserved headphone mic interface. The antenna interface is ipex-mini interface, which is small and easy to connect various antennas. On board high efficiency DC-DC power supply module, support 5v-18v wide voltage power supply, reserve power enable port, convenient control power supply, reduce power consumption of development board. The main serial port has done level matching, supporting 3.3V 5V single chip microcomputer or other control systems.
GSM, GPRS, GPS + Beidou function.
2、 Module supported data
2、 Module support data 1: support GPS, BD, glo, LBS base station positioning, all-round positioning
2: Equipped with RTC backup battery, support hot start and warm start, greatly enhance the positioning speed
3: Positioning data support GPS independent serial port acquisition and configuration, more options, more convenient.
4: The positioning data also supports GSM serial port, which can be obtained and configured through at command, which is faster and easier.
5: Computer debugging video strong attack, so that parents faster grasp the 868 function
6: Add a variety of single-chip program, greatly help the rapid development of single-chip
3、 Module advantages
1. The interface is rich, the common interface is planned uniformly, and the earphone interface is also integrated, which is led out in the way of needle arrangement to save space

2. Our power supply has enable control pin, can control power switch, can realize remote unmanned control.
3. The main serial port and GPS serial port are integrated with level matching circuit, so the compatibility is very stable.
4. Two status indicators, module status is clear, simple and fast.
5. Antenna 50R impedance matching, in a good environment, GSM signal measured up to 31 full grid,
6. Exclusive firmware, support base station positioning, when the GPS signal is poor, it can also locate normally
7. The same quality, the same chip, our price is the lowest, cost-effective relatively high.

4、 Module description

1. RTC standby power supply: supply power to RTC after equipment power failure.
2. GPS power control pin: used to control whether the GPS part in the module has power, so as to save power.
3. GSM antenna interface: connected to GSM GPRS antenna, ipx-mini antenna interface.
4. DC-DC module: MSP series high reliability power chip is adopted, and the power enable pin is led out.
5. Main serial port and power pin: the serial port is compatible with 3.3V and 5V controllers, and supports 51 STM32 and other mainstream MCU.
6. Active GPS antenna: connected to GPS antenna. The antenna interface is ipx-mini.
7. Headphone microphone interface: it is used to weld the voice microphone interface to realize the function of mobile phone( We sell microphones and loudspeakers.
8. Micro SIM card holder: direct SIM card holder, when inserting the card, the slot of the SIM card is outward, supporting various mobile phone cards of China Mobile Unicom.
