NEO-6M GPS Module

  The NEO-6M/7M GPS module features high sensitivity, low power consumption, compact size, and high tracking sensitivity, significantly expanding its coverage for positioning. It is capable of high-precision location tracking even in environments where regular GPS modules struggle, such as narrow urban skies or dense jungle areas. The module's high sensitivity, low static drift, low power consumption, and lightweight design make it ideal for applications in automotive, handheld devices like PDAs, vehicle monitoring, smartphones, cameras, and other mobile positioning systems, making it an excellent choice for GPS product applications.

Hardware Connection

NEO-6M Module    Development Board
VCC              5V
GND              GND
TX               D3 (or any other available digital pin, if using SoftwareSerial)
RX               D4 (or any other available digital pin, but can remain disconnected unless you need to send commands to the GPS module)

Usage Method

Install Library

1. You need to install the TinyGPS library or any other compatible GPS parsing library to decode GPS data. You can search for and install the TinyGPS library using the Library Manager in the Arduino IDE.

Enter the code:

  Since GPS signals are only available outdoors, the following code includes a 2.8-inch LCD screen for display purposes. For wiring details, refer to the ColorEasyDuino Module Migration Manual.
