315/433Hhz wireless module serial interface

Specifications: 2.5 * 1.9cm (without antenna)

Antenna length: 3.5cm

Voltage: 4.5-5.5V

Launching distance: open distance of 15-50 meters, 150 square feet within the basic meet (specific to see the obstacles)

Control: 5V TTL serial control

Serial baud rate: 9600bps (fixed value, can not be modified)

Support the decoding signal: encoding chip model: 2260,2262,1527,2240 end of the chip

1, this module can simulate the 2262,2260,1527 signal encoding emission, support 99% can learn 2262,2260,1527 signal equipment. (Shock resistance range: 1.8-5.6M).

2, the launch signal more than 1 million, equivalent to 250,000 4-key Mahogany remote control.

3, a variety of signals independent of each other without interference, the module optional 315Mhz and 433Mhz frequency.

4, serial communication, can be connected directly through the microcontroller serial port or computer USB to TTL connection control.

5, with 8 fixed code trigger port, without connecting any equipment, direct analog remote control transmitter signal (low level trigger).

6, the data sent by: MCU or computer serial debugging assistant, send 16 hexadecimal format data, baud rate of 9600bps

7, the data format: FD XX XX XX XX DF a total of 7 bytes of data sequentially issued.

     This module combined with single-chip microcomputer control is equivalent to an integrated multiple remote control module, you can completely replace the remote control signal transmission, but it should be noted that can not directly simulate a remote control signal, all control devices need to learn this Module signal can be controlled by this module or using the decoding module of the shop for remote control decoding, decoding and then launch the code, but also need to have a certain electronic base (will use serial communication) to complete the application.

     When used in conjunction with the decoding module, pay attention to the needs of more than 1.5 meters away from the receiver module to launch the decoding test, the distance is too close will lead to receive anomalies, such as the need to close the test can try to shock parameters to 0x90 or more

 Receiving function:

1, support the encoding chip model: 2260,2262,1527,2240 end chip decoding

2, serial output remote control source code, can distinguish between coding addresses and keys,

3, automatically adapt to the shock resistance parameters, compatible resistance range: 1.8M-5.6M

4, the signal continuous output, continuous decoding

5, the fixed serial port communication baud rate 9600bps (can not be modified)

6, the serial port only has the output function

Note: In the decoding, the transmitter (or remote control) need to decode the module from more than 1.5 meters to receive the normal, such as the use of our launch module decoding test, pay attention to the two computers directly debugging operation, too close will lead to receive unusual.

application solution:

1, single-chip microcomputer decoding module to determine the realization of the remote control signal to perform various operations

Including: remote control car, model aircraft, remote control home appliances, remote control of a variety of DIY equipment and so on.

2, computer software + USB to TTL + decoding module ---- realize computer serial software control computer software operation

Including: remote control computer software operation (need to determine the computer serial software to receive data)

3, single-chip + RF transmitter module + decoding module ---- to achieve data communication between the microcontroller and control
