What can it control?
This is the model RX480E
The name is: Four-channel output high-level wireless receiving module with decoding
There are two versions, one is single-chip and the other is dual-chip.
There are also customized versions with or without antennas and with or without pins for everyone to choose.
At the same time, this series also has a single-channel module: RX480E-1A.
Why was RX480E developed? And why is it four-channel?
RX480E is a receiving module with decoding function, which is to solve:
The need for DIY lover to develop RF remote control functions
and these DIYer do not understand or are not familiar with the encoding and decoding format of the remote control,
and will not use receiving modules without decoding functions;
The reason why it is 4-channel is that
in the original security and anti-theft industry, many remote controls have 4 buttons and
there is a need for 4-channel channel control, so 4-channel was developed,
allowing developers to choose from 1-4 channels.
We applied for a patent for 480E, so we continue to use this name.
What is decoding?
Sometimes it is not clear what code is decoded?
Is it encrypted?
In fact.
Decoding is to read the data code of the transmitted signal.
We use the decoder as a tool
The 4 channels on the back of RX480E correspond to the 4 LEDs on the decoder
Press the learning button twice
Learn the Toggle(self-locking) mode
Press the remote control button to turn on
Press the remote control button again to turn off
Select the remote control code EV1527
Press the A key
The binary number is 1000, which is 8 in decimal
1 is in the first position, so the D3 pin outputs a high level
The first LED lights up
The RX480E module outputs the high level of the corresponding channel
according to the position of 1 in these data codes.
This process is equivalent to decoding.
The one that does not decode is our RX18211A module.
Its output pin is DATA.
The output is data.
That is, what the signal of your remote control sends.
I receive and output
There is no step of processing RF signals in the middle.
So if you want to add RF remote control function to your device.
The module with decoding will be simpler and easier to implement than the module without decoding.
How to check the quality after receiving the goods
Now many merchants have begun to imitate our RX480E module
Please try to buy it on a regular platform
Recognize the QIACHIP brand
So
After purchasing the product and receiving the goods
How to confirm the quality of the module
If you have a remote control and RX480E set
You just need to power on the RX480E
The simplest quality test can be carried out
Press the learning button
Press the remote control button
Perform inching mode pairing
When the remote control is pressed
The module indicator lights up
It means that the module can be used
And the module matches the remote control
If you have a combination of a transmitter module TX118SA and RX480E.
You only need to connect the power supply to TX118SA.
Then connect a button.
The TX118SA module is equivalent to a remote control.
Press the learning button of RX480E
Press the button of TX118SA
Perform momentary mode pairing
When the button is pressed
The indicator light of the module lights up
Indicates that both modules are good
Note
If you press the learning button of RX480E
The light flashes quickly and then goes out
It proves that there is signal interference in your environment.
You need to change to an environment without interference for testing
Finally, the transmitter directly selects the remote control or module we match
If you match it yourself
Please choose the 433Mhz EV 1527 encoding
Transmitter remote control or transmitter module
Otherwise, it may not be matched
What can it control?
Many people have bought this module.
But it is still not clear what it can control.
Here we explain the principle.
For each channel of the module, the output voltage is determined by the power supply voltage.
The low level voltage is 0.
The high level voltage is 3-5V.
The output current is 10-20mA.
Then this voltage and current can drive electronic components with a working voltage of 3V-5V and a working current of 10-20ma.
For example.
LED.
The input signal of the chip.
For example, the pin input signal of the Arduino board.
If you need to control the relay.
You need to add a current amplifier chip.
For example, Darlington tube, triode.
Finally, if you have any questions or ideas about the module.
You can comment.
I will also select some good videos or posts and post them in the comment area.
For your reference.
Continuously optimize this module.
Make this module more convenient for everyone to use.
