Satellite Positioning GPS Module For Arduino 51MCU STM32
Tax included.
Description:
Working voltage 3.3v-5.0v
Current: 40mA
Default baud rate: 9600 (can be modified via U-CENTER)
Output frequency: 1Hz (can be modified by U-CENTER)
Module features:
1, with USB Micro interface, the use of ordinary mobile phone data line can debug GPS module, no longer need to use USB-TTL and other tools.
2, set aside a TTL interface, you can easily use the USB-TTL or external MCU control to receive GPS information.
3, module board loaded ceramic antenna, the open place without GPS external antenna can be put on the search satellite.
4, set aside SMA antenna interface, can use the external antenna, the ability to search more satellite
Pin definition:
1, VCC: power supply (3.3V-5V)
2, GND: ground wire
3, TXD: module serial port to send pin (TTL level, can not be directly connected to the RS232 level, can be connected to the microcontroller RXD)
4, RXD: module serial port receive pin (TTL level, can not be directly connected to the RS232 level, can be connected to the microcontroller TXD)
5, PPS: clock pulse output pin.
GPS second pulse signal PPS one second, it is used to indicate the role of the whole second moment, and the time is usually marked with the rising edge of PPS seconds pulse. Because GPS can give UTC time, but received the user is there will be a delay, then in order to get the precise timing, the introduction of PPS signal rising edge to indicate the UTC whole seconds in time, the accuracy can be to a nanosecond, and no accumulated error.
