Description
Module GPS / GLONASS NEO-7M-C on board with installed connectors goldpin. Used, supports 56 channels, works with a voltage from 3.3 V to 5.5 V, it communicates via interface UART (TX, RX) and the refresh frequency is up to 5 Hz. The module is equipped with straight 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 soldered straight 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 of 9600 bps. Thanks to the wide voltage range, it can work with devices 3.3 V, for example, STM32 and Raspberry Pi, and 5 Volts, for example, Arduino
- Built-in ceramic antenna- gives the sensitivity of -162 dB to increase this parameter, the external version can be attached via the u.FLconnector. Since most of the available antennas have SMA connector, in our offer, you will find a suitable adapter u.FL - SMA.
- The backupbattery - on the reverse side is a battery to retain data in the device when the supply voltage is disconnected.

The manufacturer provides a user manual describing the operation of the module. |
Connection and sample program
The system has 5goldpin leads - raster 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 ground 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 of the signal pulse-per-second of the GPS module. |
The module supports such software as: u-center and GoogleEarth.
