Product Information
315m 433M wireless 315MHz four channels with decoding learning receiving module
Model Number:M2021015:315M 433M
The wireless receiving module is a general-purpose remote control module integrated with a high-sensitivity wireless receiving chip and a low-power MCU. The module has the advantages of small volume, simple use, wide voltage input, low power consumption and long receiving distance. It can be widely used in various low-cost receiving and decoding circuits. The user has simple use and 4-channel control output
Features
1. High receiving sensitivity and long communication distance 2. Power consumption receiving current 6mA 3. ISM frequency band works without applying for frequency points. The carrier frequency is 433mhzp frequency band, and other frequencies can be customized 4. Long transmission distance and 3km can be achieved with remote control 5. A variety of antenna matching schemes can be configured according to the application site to achieve the best effect
Clear and check the code: (clear the code before switching the mode) the power band 1a of 5v2a does not move
1. Clearing function – after pressing the learning button key 8 times, the LED indicator goes out and releases to start clearing all remote control code data in the memory. When the LED indicator flashes 7 times, it means that the clearing function is completed. 2. Code matching function – press the learning button (inching mode) key, and the LED indicator lights up, it means that the microprocessor enters the learning code matching state, Press the matching wireless remote control button, and the LED indicator flashes for 3 times and then goes out, indicating that the code matching is successful (pressing the learning button once is the inching mode: pressing it twice is the self-locking mode; pressing it three times is the interlocking mode; pressing it four times: 1 and 2 inching, 3 and 4 self-locking; pressing it five times: 1 and 2 inching, 3 and 4 interlocking; pressing it six times: 1 and 2 self-locking, 3 and 4 interlocking; pressing it seven times: 1, 2 interlocking, 3 and 4 interlocking) the wireless remote control switch can store 16 different remote controllers and set different working modes (this paragraph is one key code matching, and the program will automatically allocate data bits)
3. Code matching test – after successful code matching, when pressing the key on the remote controller, the corresponding d0, D1, D2 and D3 output is high level
Wiring and testing
1. Correctly regulate the wiring according to the required control functions, and check whether the wiring is correct again after the wiring is completed. Do not operate the wiring and tentative wiring with power on. If there are adverse consequences caused by non-standard operation, we will not be responsible. 2. After confirming that the wiring is correct, turn on the power. 3. Press the key of the code matched remote controller, and the remote control switch controls the control object used against it. If the control object is under normal control, it means that the wiring test is successful and can be used normally

Tip
1. Do not operate with power on, turn off the power supply for operation, and turn on the power for use after the test is confirmed to be correct. 2. When the voltage of the remote controller is insufficient, please replace the battery in time (when the battery voltage of the remote controller is insufficient, the remote control distance becomes closer) 3. When using wireless electronic products, pay attention to avoid metal masks. Large electronic equipment and electromagnetic fields have strong interference sources, Avoid the short distance between the remote control and the receiver or failure to work normally. 4. Do not use this electronic product abnormally
