UNV-SIM868 development board, superior performance, small size.MICRO SIM card seat on board, reserved microphone welding port for headset.The antenna interface is ipex-mini interface, which is small and convenient to connect various antennas.The on-board high-efficiency dc-dc power module supports 5v-18v wide voltage power supply, reserves power port to control power supply conveniently and reduce the power consumption of the development board.The main serial port has made level matching, supporting 3.3v 5V MCU or other control systems. GSM GPRS GPS+ beidou function.

Data supported by the module

1. support GPS, BD, GLO, LBS base station positioning, omnidirectional positioning
2. equipped with RTC reserve battery, support hot start and warm start, and the positioning speed is greatly enhanced
3. the positioning data supports GPS independent serial port access and configuration, with more options and more convenience.
4. The positioning data also supports GSM serial port. It is faster and easier to obtain and configure by AT command.
5. the computer debugging video strong attack, let dear friends grasp 868 function faster
6. added a variety of MCU programs, greatly facilitate the rapid development of MCU

 Module advantage

1. Rich interface, unified planning of common interface, and integrated headphone interface, leading to space saving by means of pin arrangement
2. Power supply has enabling control pin, which can control power switch and realize remote unmanned control.
3. The main serial port and GPS serial port are integrated level matching circuits with very stable compatibility.
4. 2 status indicator lights, clear module status, simple and fast.
5. Antenna 50R impedance matching, the measured GSM signal can reach 31 full capacitance in a good environment with high intensity.

Module Declaration

1. RTC reserve power supply: supply power to RTC after the power is off.
2. GPS power control pin: it is used to control whether there is power in the internal GPS part of the module to save power.
3. GSM antenna interface: it is connected to the GSM GPRS antenna, which is the ipx-mini antenna interface.
4. Dc-dc module: MSP series high-reliability power supply chip is adopted, and power supply enables the pin to be drawn out.
5. Main serial port and power pin: the serial port is compatible with 3.3v and 5V controllers and supports mainstream MCU such as 51 STM32.
6. Active GPS antenna: connect GPS antenna.The antenna interface is ipx-mini.
7. Microphone interface for headset: it can be used to weld the microphone interface to realize mobile phone function.We have a microphone and a speaker for sale.
8. MICRO SIM card seat: directly inserted SIM card seat, with the SIM card facing outwards when the card is inserted, supporting mobile unicom of various mobile phone CARDS
