product detail
Product introduction:
This product is a serial port to radio frequency module with a frequency of 315MHZ. It uses a single-chip microcomputer to control the equivalent of 250,000 remote controls, which can simulate any address parameters and key values of the remote control. It is equivalent to a EV1527 million code chip with freely set parameters, which can meet 99% of the scenes!
Product parameters:
Product size: 2.5*1.7cm (without antenna) 3*1.7cm (high-power version)
Antenna length: 3.5cm
Voltage: 3.3V-5V
Support frequency: 315MHZ
Standby power consumption (rough calculation): 13.5ma (high-power version)
Transmission power consumption (rough calculation): 33.5ma (high-power version)
Launch distance: 15-200 meters in an open space, and an indoor area of 150 square meters is basically satisfied (depending on obstacles)
Control method: 5V TTL serial port control
Serial port baud rate: 9600bps (fixed value), no parity, 1 stop bit
Support decoding signal: the code chip model is: 2260, 2262, 1527, 2240 end of the chip
Oscillation resistance range: 1.8-5.6M
Interface Description:
VCC: Positive power supply (4.5-5.5V)
TXD: Serial transmission port
RXD: serial port receiving port
GND: negative pole of power supply
L: Common trigger port
A1-A8: Button ports, each port sends a signal once it touches the L port
Instructions for use:
XX: stands for customizable parameters
Address: equivalent to setting and selecting different remote controls
Key value: equivalent to setting different keys of the remote control
FD/DF frame header and frame tail: fixed values, just fill in directly
Transmission time: The selectable range is 01-FF, which is the duration of the transmission signal. The larger the value, the longer the transmission time.
Address: Choose different parameters to represent different remote controllers, as the address indicates the same remote controller
Key value: can be understood as different keys under the same remote control (same address)
Oscillation parameter: This parameter is the pulse width of signal transmission, we can fill in 60 by default
Application examples:
1. Example 1: Transmit different key signals of the same remote control, you can write as follows
｛FD0301010160DF}
{FD0301010260DF}
{FD0301010360DF}..............{FD030101FF60DF}
If you need a longer launch time, you can change 03 to 05 or 06, etc.
2. Example 1: Transmit the button 1 signal of the same remote controller, which can be written as follows
｛FD0301010160DF}
｛FD0301020160DF}
