RF Transceiver Module, NRF Wireless Module

1.What are RF transmitters and receivers?

• An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4. The transmission occurs at the rate of 1Kbps – 10Kbps. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.

2.Can I buy a RF transmitter and receiver kit?

• Yes you can buy a RF transmitter and receiver kit from authorized sellers like Robocraze. RF kit like FM Radio kit is available and contains hex3653, DIY fm receiver, frequency: 76- 108 mhz.

3.Which are the best Arduino compatible RF modules?

• RF transmitter and receiver pair is one of the best RF modules that are highly compatible with Arduino. The RF transmitter is pretty basic and is easy to integrate with your Arduino board along with the receiver. The receiver has the sensitivity of -105db while the entire logic circuitry works on 5V.

4.What is a NRF module?

• The nRF24L01 is a wireless transceiver module, meaning each module can both send as well as receive data. They operate in the frequency of 2.4GHz, which falls under the ISM band and hence it is legal to use in almost all countries for engineering applications.

5.Which are the most popular NRF modules?

• NRF24l01 transceiver module is the most popular and one of the best NRF device available in the market. 

6.What is the use of NRF24L01?

• The nRF24L01 is used on a wide variety of applications that require wireless control. They are transceivers which means that each module can transmit and receive data. These modules are very cheap and you can use them with any microcontrollers like Arduino, Raspberry Pi and other MCU.

7.What is the range of NRF24L01?

• In an open space and lower baud rate, the NRF24L01 has range upto 100 meters. It uses the 2.4 GHz band and it can operate with baud rates from 250 kbps up to 2 Mbps.
