If you are wandering to navigate the distance with a drone then this GPS Module is needed for you. GPS drones are equipped with a GPS module that allows them to know their location relative to a network of orbiting satellites. Connecting to signals from these satellites allows the drone to perform functions such as position hold, autonomous flight, return to home, and waypoint navigation.

This is a complete GPS module that is based on the NEO 6M GPS. This unit uses the latest technology to give the best possible positioning information and includes a larger built-in 25 x 25mm active GPS antenna with a UART TTL socket.

The RF Nano Integrated NRF24L01 Wireless Module with Soldering is a compact wireless communication module that incorporates the NRF24L01 transceiver chip. It is characterized by its compact size and integration capabilities, making it suitable for applications where space is limited.

The Nano Board has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega32P provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).

This hybrid 433Mhz RSI Wireless Transmitter Receiver Module provides a complete RF TRANSMITER  and receiver  module solution which can be used to transmit data at up to 3KHz from any standard CMOS/TTL source.
