Product Description Mini Size Super-Heterodyne Decoding 4CH Receiver Module Working Voltage: DC3V-5V ( the best DC5V) Size: 30*13*5mm Working Frequency: 315/433.92MHZ Optional Working Current: 3mA (5.0V DC) Modulation Mode: ASK Sensitivity: -105dBm (50) Remote Distance: 10-100 meters (open space) Output Data : 4CH High Level Signal TTL Encoding Type: Learning Button to add Transmitter Working Mode: Momentary Toggle Latched adjustable Pin No. Pin Name Instruction 1 VT Output Status Indication 2 D Data Output 3 C Data Output 4 B Data Output 5 A Data Output 6 5V Power+ 7 GND Power- Momentary .Toggle .Latched Adjusted by the Dot on the Receiver . Momentary------------Press the Transmitter button A, the receiver relay A is ON, release button A; the receiver relay A is OFF, the same as B/C/D Toggle---------------Press transmitter button A for 1 time , the receiver relay A is ON, press button A again, the receiver relay A is OFF, the same as B/C/D. Latched------------------ Press transmitter button A, the receiver relay A is ON, the relay B/C/D is OFF. Press transmitter button B, the receiver relay B is ON, the relay A/C/D is OFF. Press transmitter button C, the receiver relay C is ON, the relay A/B/D is OFF Press transmitter button D, the receiver relay D is ON, the relay A/B/C is OFF. It also mean .Latched only can keep 1CH ON .and it will often have 1CH is ON. Notes When drive the MCU directly ,the I/O port cant connect the pull-up or pull-down resistors because the drive current of RXB12s data output pin is weak.Also the inner pull-up or pull-down resistors of MCU should be disabled. 20-key mini-device project remote control / small infrared remote control / 8 m launch / send C codeModel:
