The LED is the learning indicator of the RF remote control, clearing the data indicator of the RF remote control, the control mode setting indicator, and the decoding valid indicator of the receiving module; S1 is the button, as the control mode setting, the setting button of the RF remote control learning. Application example: When the QA011 chip receives the data of the remote control that has been learned, the LED light flashes, the PB1 pin will output a high level to control the conduction of the MOSFET. Crystal oscillator can be provided by QIACHIP Function description and mode setting Clear code reset function: After pressing the learning button of the module for 8 times, the MOSFET that controls the negative electrode is turned off, and the indicator light flashes 6 times. After clearing all stored RF remote control key values, the indicator light of the module goes out. Momentary mode: press the learning button of the module once, and the LED indicator flashes once. When the LED indicator is on, press the remote control button to be matched, and the LED indicator of the module flashes continuously for 3 times, indicating that the pairing is completed. Then, press and hold the matched remote control button, the MOSFET controlling the negative pole on the module will be turned on, release the remote control button, and the MOSFET controlling the negative pole on the module will be turned off. Toggle mode: press the learning button of the module twice, and the LED indicator flashes twice. After the LED indicator is on, press the remote control button to be matched, and the LED indicator of the module flashes continuously for 3 times, indicating that the matching is successful. Then, press the matched remote control button to turn on the MOSFET controlling the negative pole on the module. Press the same matched remote control button again to turn off the MOSFET controlling the negative pole on the module. Latching mode: long press the module learning button for 3 times, and the LED indicator flashes for 3 times. When the LED indicator light is on, press the key (A) of the remote control to match. After the LED indicator light flashes for 3 times, it will continue to be on, and then press the key (B) of the remote control to match. The LED indicator flashes for 3 times and then goes out, indicating that the matching is successful. Then, press the remote control button (A), the MOSFET controlling the negative pole on the module will be turned on, and then press the remote control button (A), the MOSFET state will not change. Press the remote control button (B), the MOSFET controlling the negative pole on the module will be turned off, and then press the remote control button (B), the MOSFET state will not change. Closing function with 5S delay: press the module learning button 4 times, and the LED indicator flashes 4 times. After the LED indicator is on, press the remote control button for matching, and the module LED indicator flashes continuously for 3 times, indicating that the matching is successful. Then, press the matched remote control button, and the MOSFET controlling the negative pole on the module will be turned on. After a delay of 5 seconds, the MOSFET controlling the negative pole on the module will be turned off. Closing function with 10S delay: press the module learning button 5 times, and the LED indicator flashes 5 times. After the LED indicator is on, press the remote control button for matching, and the module LED indicator flashes continuously for 3 times, indicating that the matching is successful. Then, press the matched remote control button, and the MOSFET controlling the negative pole on the module will be turned on. After a delay of 10 seconds, the MOSFET controlling the negative pole on the module will be turned off. Closing function with 15S delay: press the module learning button 6 times, and the LED indicator flashes 6 times. After the LED indicator is on, press the remote control button for matching, and the module LED indicator flashes continuously for 3 times, indicating that the matching is successful. Then, press the matched remote control button, and the MOSFET controlling the negative pole on the module will be turned on. After a delay of 15 seconds, the MOSFET controlling the negative pole on the module will be turned off. Closing function with 20S delay: press the module learning button 7 times, and the LED indicator flashes 7 times. After the LED indicator is on, press the remote control button for matching, and the module LED indicator flashes continuously for 3 times, indicating that the matching is successful. Then, press the matched remote control button, and the MOSFET controlling the negative pole on the module will be turned on. After a delay of 20 seconds, the MOSFET controlling the negative pole on the module will be turned off.   Package Precautions:       RF devices are voltage sensitive devices. If the power supply is unstable or the ripple is large, add a filter to the power input to ensure that the power supply voltage does not exceed the maximum operating voltage of the product.       This device is an electrostatic sensitive device, anti-static measures must be used in transportation and use. When patching, make sure that the temperature does not exceed 245 degrees        It is recommended not to use a rubber-covered spring antenna in application to ensure a better product yield. The product description is subject to change without notice.   Antenna General application For general applications, antennas can be directly adapted to market specifications as follows: 433M antenna Wire length at welded end is 10mm; The total length of antenna wire straightening is 170mm; Winding turns are 9 turns.
