4 Channel EV1527 433MHz RF Relay Board Kit Wireless RC Transmitter and Receiver Board Remote Control Relay Board
Product Description
The remote control and receiving module already contain 1527/2267 encoding chip and decoding MCU. The remote control outputs 1527 internal codes, that is, all remote controls can be used independently, and the codes issued are different. After receiving the signal from the receiving module, your MCU motherboard can drive 4 relay modules to implement wireless remote control appliances, which is very suitable for smart home projects. Before use, solder the spring antenna to the ANT pad of the receiving module, and then power on, so that the remote control and the receiving module are coded. Press and hold the learning button on the board for 2 seconds, the learning indicator on the board flashes once, it indicates that the learning mode has been entered; release the learning button, press any one of the remote control keys to flash 4 times to indicate that the learning is successful, and exit the learning mode. Output method: -By default (T2 and T1 are floating) is direct mode. When the button of the remote control is pressed, the corresponding pin of the receiving module will output a high level and will not output a low level until the key is released. -The back of the board (T2 ground, T1 floating) is self-locking mode. When the button of the remote control is pressed, the signal state of the corresponding pin of the receiving module is reversed, that is, the original output low level becomes high level, and vice versa Of course. -The back of the board (T2 floating, T1 ground) is in interlock mode. When the button of the remote control is pressed, the corresponding pins of the receiving module will output a high level, and the other pins will output a low level, and this output will be maintained. Status until another key is pressed.
