Description
Module GPS/GLONASS NEO-7M-C on board with installed connectors goldpin. When used, supports 50 channels, works with a voltage from 3.3 V to 5.5 V, communicates via interface UART (TX, RX) and the refresh frequency is up to 5 Hz. The module is equipped with corner goldpins.

Attention! The module is not a product of the company u-Blox, it is a version of Wavesharecompatible with u-Blox NEO-7M. |
The system has solderedcorner goldpin connectors and a ceramic antenna.
Key features
- GLONASS system- the Russian, satellite navigation system, covering the entire globe.
- Simple connection- equipment communicates via simple UART interface i.e. RX and TX pins with default speed 9600 bps. Thanks to the wide voltage range, it can work with devices of 3.3 V, for example, STM32 and Raspberry Pi, and of 5 Volts, for example, Arduino
- Built-in ceramic antenna- gives the sensitivity of 162 dB, in order to increase this parameter, you can attach the external version via the u.FL. connector.Since most of the available antennas has SMA connector, in our assortment can be found a suitable adapter u.FL - SMA.
- The battery backup - on the back side is a battery to retain data in the device when the supply voltage is disconnected.

The manufacturer provides a user manual describing the use of the module. |
Connection and sample program
The system has a 5goldpin leads - pitch 2.54 mm. A description of their functions is in the table below.
| Pin | Description |
|---|---|
| VCC | Supply voltage 3.3 V or 5 V. |
| GND | The mass of the system. |
| TXD | The transmitter of the serial interface which should be connected to the receiver of microcontroller (RX). |
| RXD | The receiver of the serial interface that should be connected to the microcontroller's transmitter (TX). |
| PPS | An optional output signal pulse-per-second of GPS module. |
The module supports such programs as: u-center and GoogleEarth.
