## Description

HiLetgo 315Mhz RF Transmitter and Receiver Module link kit for Arduino/ARM/MCU/Raspberry pi Receiver module parameters: 1.Product Model: MX-05V 2.Operating voltage: DC5V 3.Quiescent Current: 4MA 4.Receiving frequency: 315Mhz 5.Receiver sensitivity:-105DB 6.Size: 30 * 14 * 7mm 7.External antenna: 32CM single core wire, wound into a spiral Technical parameters of the transmitter head 1.Product Model: MX-FS-03V 2.Launch distance :20-200 meters (different voltage, different results) 3.Operating voltage :3.5-12V 4.Dimensions: 19 * 19mm 5.Operating mode: AM 6.Transfer rate: 4KB / S 7.Transmitting power: 10mW 8.Transmitting frequency:315Mhz 9.An external antenna: 25cm ordinary multi-core or single-core line 10.Pinout from left → right: (DATA; VCC; GND) Package Included: 1 x Receiver module 1 x Transmitter Module

Review: Works great for RF remote sniffing - I got this to decode signal from an rf remote and then send it out for automation purposes. Receiver (no antennas attached) is not great but it worked when the remote was right up to it. Transmitter works great.
Review: Missing components, Incorrectly assembled, does not work. - The transmitter functions well, but is missing one coil. The receiver does not work at all. The output state of the receiver is never stable, and doesn't respond to any signal from the transmitter. The receiver is also missing a resistor, and there is no glue on the coil, indicating this module was never tuned at the factory. Don't waste your time, try a different type of wireless module.

## Questions & Answers

**Q: Do I need to add my own antenna?**
A: Depends on range to the access point it is connecting to. I have mine installed on wall socket about 10 feet away and have no transmission issues.

**Q: The launch distance on this says 20-200 meters. Is it able to transmit and receive a signal that it less than 20 meters?**
A: yes i would think there is no reason to have a minimum distance.  I think they probably mean it will work up to 20 meters for sure and it might work up to 200 under certain conditions.

**Q: Is it possible to change the frequency of both the receiver and trasmitter?**
A: No.  See the can on the transmitter, where it says 315?  You would have to change to different frequency component.  If you want a 433MHz, then just buy that version.  The receiver might be somewhat adjustable, but no idea how much.

**Q: Do these have to be used for data? Or are these a direct 1 to 1 from signal to output? Could I use these just the wirelessly fire a relay?**
A: “Data” is simply encoded as on or off, and checked by the receiver at specified time intervals. It can definitely be used to fire a relay, or toggle one.

### ⭐ Missing components, Incorrectly assembled, does not work.

The transmitter functions well, but is missing one coil. The receiver does not work at all. The output state of the receiver is never stable, and doesn't respond to any signal from the transmitter. The receiver is also missing a resistor, and there is no glue on the coil, indicating this module was never tuned at the factory. Don't waste your time, try a different type of wireless module.

### ⭐ The transmitter generates RF, the receiver receives rubbish. Save your money, look elsewhere
*by B***B on July 27, 2024*

The transmitter does work, checked it with a frequency counter and it's pretty close to 315 MHz. The receiver however, occasionally responded to the transmitter but mostly just output digital rubbish. I tried tuning it as others have and could sort of peak the signal but the digital rubbish never went away. BTW, no info on transmitter voltage required, mine had no RF output below 7 VDC so forget running it on 5 Volts.
