433/315 MHz Receiver - Learning Decoder Module - PT2272-ASK-OOK-TYJM01A-K-PT2262-EV1527-SC5211-HS2240
Decoding remote receiver module compatible with most learning code and fixed code chips on the market, including EV1527, PT2262, HX2262, SC2260, SC5211, HS2240, etc.
Features:
- Intelligent identification chip type, support EV1527, PT2262 learning code / fixed code IC remote control mixed use
- Compatible with most learning codes and fixed code chips on the market, including EV1527, PT2262, HX2262, SC2260, SC5211, HS2240, etc.
- Intelligently adapts to the oscillation resistance of the transmitting end, without considering the oscillation resistance of the transmitting end, and has strong versatility and is more convenient to use.
- Good local oscillator radiation suppression ability, multiple modules can work together and will not interfere with each other, does not affect the receiving distance
- TYJM01A-K supports four modes of operation: Latch, L4, T4, M4, and H4.
- Learning and mode conversion through the learning button trigger
- Supports 4 outputs, the module comes with learning indicator and VT data valid indication, the operation is more intuitive and convenient
- Decoder chip built-in EEPROM, support up to 32 sets of remote control memory
- Wide operating voltage range: 2V ~ 5.5V
- Module size: 18.8X14.8X5mm, small size, easy installation
Technical data:
- In the pulse data string of each frame learning code (eg, EV1527) or fixed code (eg, PT2262),
- It consists of two parts: the address code and the data code. In general, in the same remote control, the address code of each key is the same, and the data code for each key is different;
- In the TYJM01A-K module, after learning, the module only memorizes the address code of the remote control button and does not memorize the data code of the button;
- The module can intelligently identify the learning code or fixed code, and extract the address code from the received data to be compared with the address code stored in the EEPROM. If the same, the corresponding output mode is correspondingly output according to the received data code.
Pinout
VT - Learn button input and decode valid output, output low when decoding is valid, otherwise high impedance input state
D3 - Data output D3 channel
D2 - Data output D2 channel
D1 - Data output D1 channel
DO - Data output DO channel
VCC - Positive power supply
GND - Negative power supply
Instructions
L4 - Press the launch button, the corresponding output will output a high level and keep it until the next remote data
Changes when changing, by identifying the VT pulse recognition valid signal;
Example: Press the data code of the button is 0111, the D3 output is low and the D2/D1/D0 output is high
T4 - The four channels output independently and do not affect each other. Each time the button is pressed, the corresponding output is output. Flip once, with VT pulse output;
Example: The data code of the A button is 0010. Each time the A button is pressed, the status of the D1 channel is toggled once.
M4 - Press the transmit button, the corresponding output terminal outputs a high level, and resumes to a low level after stopping the transmission. VT pulse output
H4 - Press the transmit button, the corresponding channel output high, all other
channels are all low, and keep until the next change in the remote control data changes, by the judgment VT pulse recognition valid letter No.;
For example: the data code of the button is 1000, then the D3 channel is high and the others are low;
If there are multiple digits in the data code, it is determined according to the highest bit of the output high level. The code is 0111. According to the above principle, the D2 channel output is high and all other are low level.
The Default Setting is Jog Mode (M4)
