1.3.4MA the Silent current ultra-low power consumption.

2.Long-range,on the open environment ,transmission distance can reach 200 meters straight line

3.3-5V wide voltage

4.Support for serial pass through mode to replace the serial cable (half duplex)

5.Support IO level to follow, also means that any form of transmission digital level models.

6.Support IO level latch mode

7.You can set the frequency and set the address, and dozens of instructions, automatic filter

8.Small size (13.5 × 28.2mm).

Through to the 3.3 V voltage, and then will drag down pins 5 (has been for low), module is AT instructions mode, push the exit command mode. Instructions as described below:

1. AT

Send this command, will return to OK characters.

Example: hair AT return OK

2. AT + V

Module to return to version information.

Example: hair AT + V to return to HC-11 _V0. 0

3. AT + Bxxxx

The potter rate set to XXXX. This value is 0960 0192 00384 00576 2400480 00115 200.

Ex 1: hair AT + B4800 return OK-4800

Example 2: hair AT + B115200 return OK-115200

4. AT + Cxxx

Setting communication channel. From 001 to 127 can be chosen.

Example: hair AT + C058 return OK-058
