Best Wireless Modules For Arduino for Remote Controlled Robots and Application
While things, like coding of Arduino, are better done with wires, a lot of others, like controlling robots need wireless connectivity.
Now, the Arduino board, like many other microcontrollers, doesn’t have anything for the wireless connection. The only way for you is to attach a wireless module. This post will introduce you to some of the best wireless modules for Arduino that you can consider for wireless connectivity. Have a look.
NRF24L01 Wireless Module for Arduino
The NRF24L01 is a simple yet interactive Wireless module for the Arduino boards. The module usually comes in a set of two identical pieces that offer transceiver properties. You can use one of them as the receiver and the other as a transmitter according to your need. The modules have a set of eight digital pins for connectivity on one of its ends and can work with any version or type of Arduino boards. You can also prefer it for a clone of Arduino and even a Raspberry Pi boards.
The thing offers an excellent speed of around 2Mbps in a short-range and works perfectly with 2.4Ghz frequency. It is also highly compatible with transceivers of other models. You can easily pair it with nRF24E or nRF240 module.
The best part is the power of the module. It can work with as low as 14mA of RX/TX current. As for the input, it will need 1.9- 3.6V, which means you can power it directly from Arduino or attach it to an AAA battery set. In each case, the onboard power manager chips will ensure that the extra shock stays stored on the boards or dispatched slowly. It will not harm your microcontroller in any way.
NRF24L01+PA+LNA RF Module for Arduino
If you are looking for a radio frequency transmitter that can work on a long-range without interruption or power drops, then the Centlo NRF24L01 is a great choice. The transmitter works on 2.-2.5 GHz frequency and has an inbuilt amplifier to boost the signal strength. It can offer you a range of 1100 meters without any signal drops.
The best part, the module won’t drain your batteries for extending the range. In fact, it can work on as low as 3.6-5V even at the max distance. The eight pinned modules are also excellent in noise prevention and compatibility. The modules can go perfectly with multiple types of receiver or transceiver that’s fits your needs.
Its two-layer PCB structure further adds to its benefits, making it look premium and adding strength. There is also a cool looking antenna in the package that completes the look of this module.
HC-05 Bluetooth Module for Arduino
When it comes to short-range wireless modules, nothing beats the classic HC-05 Bluetooth modules. The compact size devices come with a high inbuilt IC and coils that provide excellent control without and signal drops. It can work at 9600 refresh rates, which means minimal latency in the command.
Another good thing about the module is that it is both a master and a slave. It means you can use it as a standalone module or as an additive to your wireless module. HC05 also offer both transmitter and receiver properties making it perfect for a wide range of application. The only problem you will face is with its power supply. The module uses around 4.5-6V of power to work properly. You can pair it with a 3.3V source, but that will decrease its reliability. Other than the voltage, this module is best in every possible way.
REES52 Infrared Wireless Remote Control Module for Arduino
The Wi-Fi and Bluetooth modules are good for a limited number of buttons, but if you want to use, say, 20 or more buttons, then the REES52 IR module is your best shot. The wireless module is a short-range transmission and recovering device that works using the infrared red light, like your television remotes. The module comes in a set that includes an IR receiver, a remote, some jumper cables, and a testing LED.
The remote has a set of 20 buttons and can work up to 8 meters with ease. Paired with the 38KHZ receiver, the thing can help you to control a wide range of robots and appliances. You can also use it for home automation using Arduino.
The best part is that you can use the set at up to 60 degrees. It is also very efficient and will never consume too much electricity. The remote uses a 160mAH button cell while the receiver can work with onboard power. Just make sure that you don’t use it outdoors. The natural infrared red light can affect its performance.
433Mhz RF Module for Arduino
If you are looking for a wireless module set that can work on any microcontroller, then consider getting an E_14012408. It is one of the best wireless module for Arduino that can offer a wide range of 50-100 meters with ease. The two-board set works with a frequency of 433MHz and pair it with an external antenna to provide this range.
It can offer you a transmission rate of 4kb/s, which may seem low, but is enough for most Arduino-based applications and robots. However, you may need to attach an antenna or, more specifically, a copper wire coil for getting a seamless connection from the module.
Other than that, you will also need an external power source. The device can work with 3V, but as the range increases, the power consumption may spike to up to 12V.
RF Module for Arduino
The RF set is the best possible wireless pair for hobbyists. The kit comes with two parts, the receiver and the transmitter, both in the same color and quality. They arrive in anti-static packaging and have an inbuilt power manager to ensure smooth functionality.
They digital module are also plug and go type and won’t need any coder or special accessory to run. You can easily attach them to your microcontroller with some jumper wires.
What makes the module so special is that it offers excellent control and is superheterodyne type. It also has amazing anti-jamming, making it ideal for industrial applications. Its low power requirement of 3-5v and connectivity range of 200-300 meters are further worth considering.
Esp8266 Serial Esp-01 Wi-Fi Wireless Transceiver
With a top-notch onboard processor and sturdy design, the ESP8266 stands as one of the best wireless module for Arduino boards. The compact devices come with eight digital pin-type structure that is easy to connect with not just Arduino but many other microprocessors and microcontroller with ease.
The high integrity module is highly preferable for DIY projects due to its compatibility and range of applications. You can use it both as a host or as a receiver. The devices also have an onboard storage, making it excellent for controlling sensors with minimal delays.
The best thing is that the device has minimal external circuitry. You can forget about damages and use it even without any shielding or special preparation. What more reason would you need to buy this device?
433Mhz HC-12 SI4463 Wireless Serial Port Module
Want to step up from the standard Wi-Fi module to something equally good or probably better? Well, the HC-12 transceiver is the best wireless module for Arduino to fit the profile.
