Tiny 12V radio remote receiver (schematic and programming guide)

This product is extremely functional, but has been designed to fit in a very tiny box with absolutely no room for wires. You may need to modify it to make them fit, noting that running wires past the antenna may reduce its range.
That said, the design is good and the software in the ubiquitous little 8 pin microcontroller is very functional, allowing several remotes to be added with completely different functions assigned to each remote. This type of module is usually compatible with most of the generic remotes available on eBay. That makes it more versatile than the "kinetic" self-powering remote control systems, which tend to use proprietary codes. Although the common remotes do require a small battery, in most cases it should last for years and is cheap and easy to replace.
Here's how to program this unit and many others that use the same software.
To clear all codes press and hold the button for about 5 seconds until the LED starts flashing.
To program each mode, press the button between 1 and 7 times, observing the brief LED flash with each press. After the required mode has been selected the LED will light to show it's waiting to receive a signal from the chosen remote button.
Press the remotes button and the LED will go out, or if it's the two button toggle mode it will blink and then wait for the second button to be pressed (which doesn't need to be on the same remote.)
If desired you can pair several other remotes by repeating the procedure. They can all have different functions.
Modes:-
1 - Single button momentary action. Non latching.
2 - Single button toggle on/off.
3 - Two button on/off. Each button is assigned independently.
4 - Single button timer 5-second delay.
5 - Single button timer 10-second delay.
6 - Single button timer 15-second delay.
7 - Single button timer 20-second delay.
Further presses will blink the LED, but just give the last 20 second delay mode.
Some similar units have an adjustable link for setting the mode. It usually offers momentary, latching or two button toggle. The button may only be for learning a code.
These units are common on eBay, usually supplied with a remote switch or key fob with a frequency choice of 433MHz or 315MHz.
The RF chip may be a VI590R. Here's the datasheet:-
datasheet.lcsc.com/szlcsc/2012211239_VIBRATION-VI590R_C968713.pdf
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-
www.bigclive.com/coffee.htm
This also keeps the channel independent of NLcameras's advertising algorithms allowing it to be a bit more dangerous and naughty.

    If you are interested in the profesh edition of these thingies, including mesh / point to point network, chip ids, switching, flags and data transmission (rs232), take a look at IRIS Base. They come around 50 bucks a module. i used them and their "up to 1km range" is not exagerrated. and if it doesnt work just drop an additional one in the middle. (there are industrial prebuild versions available but heaploads more expensive)

    The best thing for the receiver side of these is you can add any antenna you want without risking a fine by the transmitterpolice people, dual-quad worked fine for me, you can use a dvb-t antenna calculator for it entering the proper mhz...

    I honestly dont care if there is a cr2032 or similar in the switch... if you dont press it it doesnt use energy. what i hate are remote control receiver powerplugs (or IR sensors) who are wasting away multiple watts of power if in "standby" or holding a cheapo relais, (bad cheapo design) 24x7, just because people are too lazy or stupid to use a (cord/pull) switch. (lost mobility due to sickness excluded)

    Probably just an ASK modulated signal. Chip too tiny to handle other stuff given it also handles digital input. A tiny SA602 has a mixer and an oscillator on the same chip, but analog inputs, to transmit anything you have to PWM or PPM the signal. I was hoping for some clues. Anyhow, I need to make something that would penetrate 3 floors to my power outlet to figure out which power line is on when we experience power outage and auxiliary power is on. Don't want to go higher than the FM media broadcasts and probably the HF bands would be for HAM operators. Got to find some middle ground. What's the range on these things? Could you go 30 meters without signal fading much?

    10:10 Looks like the relay is rated to switch mains voltage, so you definitely want that separation between the traces. I'm a bit concerned about the trace for the NC contact so close to the edge of the board, but I guess it's OK since the board is stuffed inside a plastic box.

    Great video Clive! I feel like these little radio remote receivers with relays in them are things that sometimes get left by the wayside in making your own smart home stuff. Yes, it's very easy to rig up an esp8266 which is always pulling the internet but these things use remarkably small amounts of power um and as you can see none of the switches on the table there are connected to any kind of power source and that's because the batteries in them last a very very long time.

      The Chinese units do often use less than ideal separation. For extra safety you could possibly add a sleeved 100K half watt resistor in series with the touch sensing wire. (Half watt for its higher voltage rating.)

    I've got an iVac shop vac that uses a 433MHz transmitter/receiver setup. I'm hoping to figure out how to use an ACS712 hall effect sensor module to sense when a tool is drawing current and provide an input to an ESP32 to signal the need to turn the iVac on/off. I just need to work out how to get the ESP32 to send the correct 433MHz signal to the iVac receiver. The transmitter and receiver use dip switches to configure channels like old school garage door openers did. Not sure how that impacts the signal for the 433MHz on/off. Are you aware of a way to 'capture' a 433MHz signal with an arduino to then play back somehow?

    The other data pin maybe a carrier detector, these also double up as am detectors, where the other maybe FM. I have used similar modules, where the second output is a carrier detector that can be used to gate the data signal, making it less susceptible to interference. The carrier detector can also be used to identify jamming signals, maybe from similar units. There are all sorts of questions about the RF receiver. What is the modulation used? what is the carrier frequency? What is the range of the switch to the receiver? It would be nice to scope the receiver signals and workout the modulation and packet length. Do you know if the codes used are open source? These units are clearly very hackable, maybe replacing the transmitter buttons with the output from a sensor or alarm.

    I was thinking... how about doing "smart home on the cheap". checking some automatic cheap ebay/alliexpress power/light addons. I love playing with photoresistors and movement sensors, and I think more people should use them because they really slightly lower power bills. And now we can buy automatic switches or wifi switches like for 2 bucks, and there are cheap and easy to install light/movement sensors that you can use with existing lights that, and people dont realize how cool and useful they are. No need switches, lights go on depending on time/lighting conditions and if someone is in room/corridor, when you are out and eg forgot to turn off something you just open app and turn off power to specific room in your home or specific contact. and all that using 2euro wifi switch.

Kind of like I bought a laser printer because I got tired of printing out my taxes once a year and having to replace the entire ink cartridges on an old inkjet printer annually. Only paid $50 USD for the printer, and the cartridges come to twin pack for 20 bucks USD and each cartridge is good for 5,500 pages... I'm on year three on the cartridge that came with the printer, still prints flawlessly with no lines or anything so whatever I guess haha. Love your stuff man, I think I've learn more about electricity and electronics from watching your videos than I did back at University.

    I've used similar modules on electric gates . 433mhz is not as secure as rolling code but on low level security scenarios it's cheaper to buy the receiver and a few remotes than buying the brand remotes for the gate. Also if you want lights on your piers they're ideal. You have permanent supply(and a pipe to the far side pier for the motor) at the gate but can't get switch wires to the house.

    i have the same unit that i use to turn my hp computer on remotely, using the 12 volt standby, if you want to use them to turn on a computer with a 5v standby, change the relay to 5v and bridge the polarity diode, though i think the relay should still work with 4v and the bridging might not be required, and tap into the on off button wires on the relay switch terminals, with the remote set to jog, with the computers power on button, for button a and the reset for button b on the remote, for the reset button you need a 2ch relay

    Thank you I just bought one of these modules and needed the instructions. Another use for the time delay is say running a fan or dust collection system for a few seconds to make sure the debris is completely collected. I say this because it really confused me on the dust collection system that I'm becoming acquainted with. Other than not getting the remote and module that were pictured I wanted on off and a relay and i did not get that. I got them a few weeks back. It's good to know that they are interchangeable if I were to want to pick up another one I could choose the remote I actually want to use with it. I really like the car keychain fob with the silver edge it's got some nice weight to it.

      Oh yeah forgot to mention my plan was to make a remote to control the inverter I have in the car. I got the extra wired remote panel which I reverse engineer shocker. it's got a switch, 2 LED's a 6 pin phone cord consisting of 2 grounds, 2 light signals and 2 switch contacts. So my plan was to switch the switch contacts and possibly draw power or use a coin cell with the the receiver. Power supplication need to be investigated.

    the "filter and fuse box" was a common accessory attached to car stereo receivers. supposed to remove noise from your audio system...although it usually doesn't. www.alibaba.com/product-detail/Automotive-filter-fuse-box-wire-harness_60358609956.html

    Please dont buy the 433MHz version, it interferes with 70Cm ham radio, and 70Cm ham radio may interfere with your remote

    Sometimes 432 and some change is close enough to 433, sometimes it's not. Do you have a sufficiently accurate frequency counter to tell if the kinetic switches are simply not close enough? I'm suspecting they're either a bit too high or a bit too low. Other likely possibility is the pulse width is insufficient or shaped wrongly. Compare the outputs of the kinetic and battery switches on your 2 channel O-scope. (I'm asking you to do so because I can't seem to find any of the kinetic switches where I am and I have a bug up my ass about Amazon and Ebay right now.) You do have a 2 channel O-scope, right?

    I'm guessing the kinetic buttons don't work because their signal duration isn't long enough for the receiver units to be recognized.

      I wouldn't use it for high current. It could switch an external relay.

    The long 4 button remote is the same as I got with some floor lamps I got recently, but the lamps have no accessible program button I've found, so I have 2 identical but unique remotes I must use both. It's a pretty nice feeling remote, we shall see how long that weird battery lasts. At least mine has part numbers on the transmitter ic that had some information online about it. If only it had an fcc approval marking on it, I'd try to get a few more of these, especially since my modified Sonoff RF can send out the codes as well with substantial range. That programmable receiver seems pretty awesome.

    I used to use radio frequency operated switches for the electrical sockets in my house. I had to stop using them because somebody kept turning my lights off. Maybe a neighbor with the same or similar type of switches. I don't know.

    That red button probably doesn't transmit on 433mHz. Maybe a separate frequency dedicated to emergency off buttons? That's what it looks like.

    It looks like you could snip the extra leg length off the remote board so it can slide back 1mm or so to make a bit more room for the wiring to be attached in the front. BTW: What keywords did you use to get this particular unit?

      Search for 12V 433mhz remote receiver and you should find some. Usually under $£€5

    2044 is probably just the usual year-week date code. If they're deriving a higher frequency from the 13.52... MHz, they'd be using a PLL (phase locked loop). Too bad they choose a generic box meant for something else. If the holes had lines up with the terminals, this could have been nicer. I'd consider making a special 3D printed box for this, perhaps with strain relief built in. IMO, the text describing the modes isn't obsolete. It is correct and lists the most important modes, and then you're just expected to remember the time delay modes yourself. The 220 ohm resistor is only dropping 220*0.003=0.66 V. Even with the LED and transistor active, that's only an additional 3 mA max. The regulator isn't close to dissipating even 100 mW. My guess is rather that the 220 ohm resistor is there for noise/spike suppression, including from the relay coil.

    Thirty-two times the crystal frequency plus the 860 kHz IF frequency used in many of these receiver chip results in a receive frequency of 433.54064 MHz -- right about LDP433 channel 20 (433.550 MHz)
