Module parameters: Operating voltage: 3V~5V suitable for battery-powered environment Remote control distance: Up to 8 meters Module size: 15 x 30mm with LED status indicators Installation: 3mm screw holes Module interface: VCC supply positive 3.3~5V GND power supply negative electrode OUT output 5V low logic level signal OD power driver output pin; Remote control instructions: 1. Receiver module is powered default output is low OUT / OD low 2. Click (first) remote control button the receiver module output goes high and remains; while indicating LED lights (OUT: high) 3. Click (second) remote control button the receiver module output immediately goes low and remains; while indicator LED is off (OUT: LOW) 4. Whole receiver module kits work as follows: press the remote control buttons at the control receiver module "on" (output OUT from low to high); press the remote control button controls the receiver module "off "(output OUT from high to low) 5. Receiver module also provides another way to power drive circuit through the receiver module output of the "low" level the control MOS transistor of the "on" "off" to the effect of driving external power devices (MOS tube maximum drive capability 20V 1A)
