This pair consists of an RF transmitter and receiver. These can be interfaced with Encoder and Decoder ICs. For better accuracy, antenna should be used at transmitter and receiver ends.


  • Frequency: 433 MHz.
  • Modulation: ASK
  • Receiver data output: High - 1/2 Vcc, Low - 0.7v
  • Transmitor input voltage: 3-12V (high voltage = more transmitting power)
  • Receiver Input Voltage : 3.3-6V (high voltage = more receiving power)
  • Transmitting range (work at 5V): 40m indoor, and 100m in open air

Do this module support UART?
Fahad | Nov 15,2012 at 01:01 PM
Sazzad7 | Feb 24,2013 at 05:18 PM
Does this module support baud rate(USART) of 9600 or higher?
Fahad | Feb 25,2013 at 12:50 AM
No, it isn't.
Sazzad7 | Feb 25,2013 at 01:26 AM
may i know the maximum baud rate ?
A.R | Feb 25,2013 at 11:58 AM
The maximum baud rate is 4800bps.

How can I use it as a remote controller? I want to control two motors with this.
A.R | Apr 18,2013 at 11:01 AM
You can get some idea from this tutorial. we have controlled relays by RF module.You can do the same with motors.Though in this tutorial we've used Piduino,it is compatible with any microcontroller.
Anikpro | Apr 18,2013 at 01:54 PM
Hmm I have do a lot of work to use it.
can you bring 2.4 GHz 6 channel radios and receiver? I need one for RC some RC application.
A.R | Apr 18,2013 at 02:58 PM
Hope you have already got our mail about your enquiry.
Anikpro | Apr 18,2013 at 04:02 PM
Yes, but I'm not interested about that Way because bringing a single one is very costly. If you bring some of them, it will be cheaper. So please bring them as a regular product of your site.
A.R | Apr 20,2013 at 10:59 AM
Ok.We'll think about it.
Sanjid | Apr 29,2013 at 02:07 AM
What is the transmission range of this kit? How far(meter) it can transmit data?
Fahad | Apr 29,2013 at 03:42 PM
40m indoor, and 100m in open air.
Bd275 | May 4,2013 at 10:53 AM
Are you have A434 transmitter and receiver and HT12E&D?
A.R | May 5,2013 at 09:37 AM
No.We don't have these transmitters and receivers.
Fkfaisal | May 7,2013 at 04:52 PM
can u bring this for us.
A.R | May 8,2013 at 06:05 PM
We'll think over it.If you wanna buy this from seedstudio through us,please fill up this form.
Dweep08 | Jun 5,2013 at 01:00 AM
i've purchased the item but datasheet is missing. I need it immediately, it'll be great if email me the datasheet.
A.R | Jun 5,2013 at 09:40 AM
We purchased this product from seeedstudio.They didn't provide us any datasheet.Only the wikipage is available,of which we have given the link in the product description.
Dweep08 | Jun 7,2013 at 01:38 AM
hurrr mia >:o
Fahad Mirza | Jun 7,2013 at 02:30 PM
Mind your language, or we are gonna ban you.
Rahul.iub | Aug 19,2013 at 11:04 AM
please provide a arduino example code for this RF module..... I tried many example but none of them works...
Mrinmoy | Oct 1,2013 at 08:00 PM
when it will be available
Risajal | Dec 10,2013 at 01:07 PM
How can I pare this to module? What is the basic communication method? Please explain.
A.R | Dec 10,2013 at 06:35 PM
You may need encoder and decoder IC depending on which module you want to interface.Please go through the wiki page of the product for clearer idea.
Astable | Dec 24,2013 at 11:43 PM
1.I need much time will be needed to be is out of stock.
2.I want to use this in a rc system with encoder and decoder ic.but in my project diagram tx has 6 and RX has 8 pin.vcc and ground are double.anyway is it possible to use this as a rc system with HT12E & D.
3.I want to control several loads from far.have you any suggestion plz?
A.R | Dec 29,2013 at 10:31 AM
1) These are from China so,at least one month will be needed.
2) Yes,these are compatible with HT12E and HT12D.
3) We will suggest you to check the transmission range first because we don't know by 'far' you mean how far.
Astable | Dec 29,2013 at 09:58 AM response!¡!!!!....I thought this site as a
active one.
A.R | Dec 29,2013 at 10:26 AM
Of course it is! And we have holidays like others too.
Astable | Dec 29,2013 at 10:49 AM
haha...holidays...anyway...I want to purchase many parts but I think you would not be able to deliver before 5 January....anyway...100m range is enough ... I will wait...thank you for response....have a nice holidays.
A.R | Dec 29,2013 at 02:54 PM
We are open now! If you want this pair,that will not be possible by 5th January. But if you want any other in stock products,please place your order without any hesitation.
Astable | Dec 29,2013 at 03:03 PM
I will take it from kushtia so I was thinking about the transportation I prefer S.A. paribahan...anyway...I will place my order soon
Anjan.Bkb | Jan 29,2014 at 09:06 PM
is there any datasheets or something like to interface the module
A.R | Feb 3,2014 at 11:20 AM
There is no datasheet. Only the wiki page where all the details are given.
Icmtech | Feb 17,2014 at 07:54 PM
Is there any available module for 125 MHz??
A.R | Feb 18,2014 at 05:48 PM
no. sorry.
Nafiz | Feb 19,2014 at 01:18 AM
need the wiki link.please reply.
A.R | Feb 19,2014 at 09:39 AM
We had the wiki link here earlier but later we found out that the current lot of this product does not match with the previous ones. The previous ones were 433 MHz and so was stated in the wiki page too. But the current lot we got is 315MHz. This is why why removed the wiki link for this time being. Sorry for this inconvenience.
Atifmahbub | Jul 11,2014 at 10:51 AM
need this one. when it will be available?
Mdrazu | Aug 8,2014 at 10:47 PM
How can i know more about this >>>>>>>>>>>>> Data sheet where?

Is Encoder and Decoder IC for This RF Module is Available Now?
I Couldn't Find Here. If not will it be Available in October or in 1st half of November?
I'll Purchase This RF Module in October and Also Need Encoder and Decoder IC Compatible with This.
If You Could Give any information about The Model No.of Those ICs and My Queries. Thanks in Advance.
Asifcuet | Sep 14,2014 at 01:36 AM
Is HT 12 E and HT 12 D is Compatible with this?
A.R | Sep 14,2014 at 11:16 AM
Asifcuet | Sep 14,2014 at 07:01 PM
Please Answer to my Previous Question.
Will Any Encoder and Decoder IC
be Available in Techshop Soon?
A.R | Sep 15,2014 at 09:52 AM
Oh sorry. I though that you had already found. We have HT12D and E.
Asifcuet | Sep 16,2014 at 11:28 AM
Thanks a Lot... I lIke Whole Onnorokom Group Very Much...

Azim_rashed | Dec 1,2015 at 09:26 PM
I need antenna for this product. Have any antenna in stoke? I have made antenna bit it's not working. what can i do to work with RF?
A.R | Dec 2,2015 at 09:38 AM
No. We don't.Soldering a copper wire will serve the purpose pretty well.
Mahdihasan | Jan 24,2016 at 12:39 AM
how can I use this as audio transmitter and receiver? please give me a diyagram.
A.R | Jan 24,2016 at 12:17 PM
Sorry, our job is to sell parts. Any type of circuit design, coding etc. must be done by the customers themselves according to our policy.

how many channel this module has?
Ikram076 | Aug 2,2017 at 05:39 PM
Can I use this for, say, controlling a car via remote and Arduino?
A.R | Aug 3,2017 at 09:56 AM
You can.
Ikram076 | Aug 7,2017 at 11:57 PM
Do I have to use encoder/ decoder? Tell me everything I need except the motors and wheels and Arduino please. Thanks.
A.R | Aug 8,2017 at 09:47 AM
Yes encoder,decoder needed. We have another with encoder and decoder. Here is also a bangla tutorial on this product
Once you see this, you will have an idea about your needed parts.
Alpha01a | Nov 24,2017 at 05:19 PM
Can I make walkie talkie with these?
