QIACHIP 433MHz Wireless Remote Control Switch Mini Receiver Built-in Learning Code 1527 Decoding 4 Channel Output with 656 FT Long-Distance 4-Button Transmitter White

I really like these things for my little hobby projects. The remote control is nice-looking, has a nice feel and works great. As an extra, as well as using the the nice controller, I also purchased and use the bare-board transmitters. Using the bare boards, my Arduino 'presses' buttons 1 through 4 acting as the remote controller. I also use the Arduino to take the output from the receiver to do things. I was robbing transmitters and receivers from toy cars but that's pretty messy. Those boards are big and frequencies unpredictable (within their general range), so I've had the wrong project triggered by the wrong transmitter. The Qiachips can apparantly control large numbers of individual projects with no overlap.

The remote buttons A, B, C, D do not correspond to control digital outputs D0, D1, D2 and D3. They are reversed such that A=D3, B=D2, C=D1 and D=D0

way easier and more reliable than using just a reciever, the dedicated gpio pins for the buttons definetly make sure it works correctly. would use this instead of just a remote and reciever anyday

Got this to add some RF remote capabilities to my arduino project. Was easy and straight forward setup, and range seems to be adequate even without the supplied antenna attached (which appears to require soldering). I didn't have a soldering kit, so went through without the antenna, and the range seems to still be enough for my purposes. Tested at least 20-30 feet, through a thin aluminum case, through 2 wooden walls, might have even pointed the remote in opposite direction as well, but don't remember. EDIT 2023: Moved the project into a vehicle, and range became horrible, even with antenna soldered to chip! The range is now barely 5-10 feet, and remote must be pointed directly at the device getting closer to the 10 foot range. Not sure what the issue is, reaching out to qiachip support through email, otherwise, may need another solution for my project. The only issue, which was kind of a big one to be honest, is that the remote did not come with a battery, and is some off size battery (at least to me) I think the size was like A22 or A23 or something like that. Obviously can just order a battery online or whatever, but I was trying to make sure if what I was attempting to do with my arduino project was even possible in case I needed to change directions, so I tried to get a battery local. At 10:00 at night, Walmart was my best option, I thought. Online it showed 3 locations near me had this size in stock. All 3 of them did not. By close to 11pm, there was 1 more Walmart I could have checked, but would not have made it by closing (close at 11pm here). Finally went to a 24 hour walgreens about 20 minutes drive away from me, and they thankfully had the correct battery size. That being said, can not really knock the product for this issue, but apparently it's not a typical battery size, and most places around me seemed to not have them in stock, so definitely would have been nice to receive a battery with this

The unit worked perfectly as advertised. I was pleasantly surprised by the remote. It came with the 12vdc battery and was easy to hold and use. The price is right too. I used the unit to drive a voice module. I used a 2N2222 transistor to convert the high output to low which is necessary to control the voice module. Worked great. The best part is NO relays. I gladly give this a five star.

i put this at 2 stars to get attention. the lights they say come on for programming don't match the instructions momentary and toggle return same confirmation. latching does NOT stay on and then get turned of manually. makes one think defective. then once programmed for toggle / latching one might presume the light was stay on when active but that's not the case. THEN, they have the buttons programmed in reverse. Button A → D3 (not D0),Button B → D2 (not D1) Button C → D1 (not D2) . Button D → D0 (not D3). Either they have a bad batch and it all works just doesn't match very well written instructions and/or its odd that such obvious confusion not notice in all the higher reviews. I bought two and both behave this way. So in summary, they do work. I asked alexa to help and after troubleshooting the suggestion was defective and i asked gemini and it said to test the pins and it all works.

Pins D0-3 didn’t work at all. Luckily the RT did. I guess it’s just hit or miss on the quality and I got unlucky. And yes I paired the remote and put in the proper mode.

This is the way to get digital programmable remote with extended range for 9 bucks. Remote will work with lots of stuff like SONOFF R3 switch. You can also get 2 for 15 bucks from another seller. I did not need 2 that's why this is good deal for me.

La portata e la selettività sono ottime. Il ricevitore va' abbinato ad un circuito di decodifica.

Kompaktes und zuverlässig arbeitendes 433-MHz-Empfangsmodul. Lässt sich problemlos mit Arduino nutzen, gute Reichweite und stabile Signalübertragung. Ideal für DIY- und Smart-Home-Projekte. Für den Preis absolut empfehlenswert.

Module sans fil fiable et facile à intégrer, parfait pour les projets Arduino. La portée et la stabilité de connexion sont excellentes pour ce type de produit. Super facile à intégrer

Utilizzato per controllare a distanza un motore stepper ed un servo tramite un clone di Arduino. Si integra perfettamente nel codice perchè non ha bisogno di alcuna libreria, bisogna semplicemente inviare l’output desiderato quando si riceve l’input proveniente dal pin digitale collegato allo specifico canale del ricevitore. Per quanto riguarda la portata è ottima, prende attraverso i muri di casa a svariati metri di distanza, in campo libero ho testato fino a 30 metri circa e riceve alla perfezione, credo posso ricevere da ben più lontano. La prima volta che si accende bisogna impostare la modalitá di ricezione desiderata premendo il pulsante presente sul modulo altrimenti non funziona nulla (bisogna farlo solo la prima volta poi funziona sempre appena viene acceso) io ho impostato la prima modalità. Il telecomando è di buona fattura e ha le pile incluse quindi è un ottimo prodotto dopotutto per 10€.
