Product Information
Wireless remote control kit receiving module transmitting board remote controller
Model Number: M2021017
Remote Control Parameters
Working voltage: DC12V, modulation mode: ask, working current: 10ma12v, transmission frequency: 315 / 433MHz (sound meter frequency stabilization), radiation power: 10mw12v, encoder type: fixed code
Decoding Receiving Board Parameters
Working voltage: DC5V, working temperature: – 10 ℃ – + 70 ℃, static current: 4.5mA, coding mode: pad coding (fixed code), modulation mode: (ook), size: 41 * 23mm, receiving sensitivity: – 105dbm, working frequency: 315MHz
Working mode: m inching transient output, which is equivalent to the state of self reset switch. It is output at high level by receiving information, and it is low level when there is no signal; L latch is low when powered on, the received signal outputs high level and locks high, and the received signal outputs low and locks low again; T is low when self-locking is powered on, receives the signal, outputs high level and locks high, and sets other outputs low at the same time
Interface Description
Vt output status prompt, D3 data output pin, D2 data output pin, D1 data output pin, D0 data output pin, 5V power supply positive pole, GND power supply negative pole, ANT connected to antenna terminal
Signal Transmitting And Receiving
The keys A, B, C and D on the remote controller correspond to D0, D1, D2 and D3 of the receiving module respectively. Press and hold the transmitting signal, and the corresponding data will output high level. The first to eighth pins of the transmitting module ic2260 and the receiving module ic2272 are address coding pins. Each pin has three states: high, low and suspended. Connected to h means 1, l means 0, and not connected means *. As long as the code on the remote control module is the same as that of the receiving module, it can communicate, but it is not allowed to communicate.
VCC voltage shall be consistent with the working voltage of the module, and power filtering shall be done well; The antenna has a great impact on the receiving effect of the module. It is best to connect the antenna with 1 / 4 wavelength. Generally, 50 ohm single core wire is adopted. The length of the antenna is about 23cm for 315M and about 17cm for 433M; The antenna position also affects the receiving effect of the module. During installation, the antenna shall be as straight as possible and away from the shield, high voltage and interference source; When in use, the receiving frequency and decoding method shall match the transmission.
Working mode: M4 (inching: output when pressing and holding, and stop when releasing) L4 (interlock: four channels can only have one output at the same time) T4 (self-locking: four channels output independently of each other, and do not affect each other. Click output and then click to stop output)
