How to use:
VIN connected to the positive of power supply , GND connected to the negative of power supply;
P connected to the positive of Motor power supply, P- connected to the negative of Motor  power supply;
M M- are connected to both ends of the motor
 
After power, D1 flashes 3 times, D2 off, M output positive, M- output negative, motor forward; after a time delay T1, D2 on, M output negative, M- output positive, motor reversal; after a time delay T2, D2 off, M output positive, M- output negativ, motor forward;and so on.
 
T1: indicates motor Forward delay time, default 0.1-5000 seconds adjustable (step 0.1 seconds)
 
T2: indicates motor Reverse delay time, default 0.1-5000 seconds adjustable (step 0.1 seconds)
 
By "Time multiple selection" setting,The maximum delay of up to 40,000 seconds
 
How to Set Up:
After power, D1 3 blinks, Enter the "work mode"
D2 on Reversal,D2 Off Forward
Press and hold the Key for 2 seconds,D1 on,enter the "setup mode"
D2 off, It's forward "setup mode"
In forward "setup mode", the continuous trigger KEY twice ,D1 off,entry "Standby timer mode"
In the "Standby timer mode" ,trigger KEY start timing(entry "Timing Mode")
D1 flashing said it is timing("Timing Mode")
Trigger KEY again to stop the clock(exit "Timing Mode")
D1 flashing time is forward time(T1) 
 
Press and hold the Key for 2 seconds,D2 on,enter the Reverse "setup mode"
In Reverse "setup mode", the continuous trigger key twice ,D1 off,entry "Standby timer mode"
In the "Standby timer mode" ,trigger KEY start timing(entry "Timing Mode")
D1 flashing said it is timing("Timing Mode")
Trigger KEY again to stop the clock(exit "Timing Mode")
D1 flashing time is Reverse time(T2) 
So far, forward time(T1) and reverse time(T2) is set up
Re-power in "work mode"

Size(without antenna): 74x24x16mm
Weight(without antenna):18g
Module features
 
Long-distance wireless transmission (up to 500 meters in open area , 10kbps baud rate in the air )
 
Operating frequency range ( 433 - 458.5MHz , up to 255 communication channels)
Maximum 100mW ( 20dBm ) transmit power ( 10 levels of power can be set )
Built-in MCU, use serial port to communicate with external devices
 
Send 31 bytes at a time
 
The module can support one-to-one, one-to-many transparent transmission communication through ID setting Changing the baud rate of a different serial port will synchronously change the rate at which data is sent over the air. ( 10kbps-100kbps)
 
Set the ''critical three minutes''. The module can send and receive data normally within three minutes of power-on. You can send the AT command '' AT ENABLE=1 '' to make the module enter the AT command state for parameter setting. There is only this reserved word in these three minutes. After more than three minutes, you will not be able to enter the AT command mode, you can only send and receive data, '' AT ENABLE=1'' will also be sent out as data, there are no reserved words at this time.
