I used ChatGPT to write an RX and TX sketch and they worked for a while and then quit. There must be some extra fine tuning involved because the sketch worked once. I can not recommend this product.

Not tested yet,,as they need soldering the antenna,, they seems work fine

I deleted my previous review; it just took some work to overcome those complaints. I settled on the RCSwitch.h library and modified some code to write a sniffer to read from my remotes. Once it worked, it was awesome!The codes that come in are integers, so use a binary converter to convert those into what were 19 bit binary codes for me, then add 5 zeros to the front (the receiver only likes 24 bit so far as I can tell, nothing else worked) and then do yourSwitchName.send(). Also be sure to know your interrupts, it's not pin based (well, it is) but interrupt based as far as initializing it: int0 is pin 2 and so on. Also, some of the code I found out there was manually powering the unit with VCC HIGH or LOW and GND LOW ... but I took that out so ended up with about 30 lines of code for a working sniffer.With the antenna soldered on, it's getting about 30 feet of range in a room with no obstructions. Have not tested it in other locations, but I will now that it's working.Happy tinkering!!

These are much better quality than similar RF modules on amazon. Worked right out of the box and I'm impressed by the range. Getting very consistent results from several rooms away (in an office with metal studded walls).

I built a controller and remote controlled car on breadboards with PIC18 series PDIP packaged microcontrollers with the chips placed straight into the breadboard with control code I wrote myself. Since I had no radio modules at home to try out it was controlled by a long wire with UART running at 9600 baud with 3-byte commands transmitted every 20ms.I was practically able to drop these in place of the wired connection. Just raw uart pin from the controller mcu straight into the transmitter, raw reciever pin into the uart input on the robot's mcu. The only code I needed to change was the baud rate. After looking at the transmission on the receiving end under my oscilloscope I decided that 9600 wasn't going to work. 2400 was what I tried next, knowing that I was being both conservative on meeting deadlines in my code and on making the signal clear. For my application this left headroom on both ends and worked great. I tested various baud rates under the oscilloscope. At 4800 baud you may be able to get it to work with a resilient protocol but it's a bit fuzzy. 3600 seems to be the highest speed that's gives a consistently usable signal.Overall I appreciate how simple it is to use this module even outside of a hardware ecosystem like arduino.If you are on arduino you won't necessarily need to mess around with some library on github- just try hooking it straight up to uart.To clear up any pin related confusion, as I didn't find any datasheet for all this:Transmitter: Just leave the Enable pin disconnected as suggested by this store page.Receiver: Both data out pins are the same. Solder both antenna pins to the antenna. For some reason the store page suggests that one of those pins is ground; it is not. It's another antenna pin.(Both): Another review suggested that 5v power doesn't work, but it did for me.Also if it matters to you this probably isn't RoHS/lead free, you can tell by how shiny the solder is.
