1、The module supports for NMEA standard protocol output, built‑in FLASH, and can save setting information when power off without external for EEPROM. The module has its own signal indicator, which indicates whether the GPS is receiving information. 2、This module not only has a ceramic antenna onboard, it can be used for satellite search and positioning in open areas without an external antenna 3、At the same time, the module is also welded with an for SMA head, which can be used for an external antenna to make the satellite search and positioning ability stronger. 4、When using, we can squeeze the GPS module through the micro usb interface of the module, use the mobile phone data cable to debug the GPS module 5、And also use the USB to serial port module or an external microcontroller to control the reception of GPS information through the serial port reserved by the module. Item Type: GPS Module Material: Synthetic cardboard Purpose: This is a GPS module, which takes NEO-7M as the core and can be used for satellite positioning. Suitable for car navigation, handheld positioning, wearable devices, DIY experiments Working Voltage: DC3.3-5V Current: 40mA The Default Baud Rate: 9600 (can be modified through U-CENTER) Output Frequency: 1Hz (can be modified through U-CENTER) The Highest Positioning Accuracy: Approx. 2.5meter / 8.2ftNote: Pay special attention to if you connect an external antenna, you need to remove the C2 capacitor on the module and place it on the internal antenna and external antenna at the same time, which will cause conflict and affect positioning. Because there is no satellite signal indoors, the module can only be used outdoors and cannot be used for positioning indoors. The positioning accuracy of the module is up to 2.5 meters. 1 x GPS Module 1 x Connection Line
