Description:

The IO port outputs a 3V level, which can drive small LEDs. If you need to drive relays and other devices, please add an amplifier circuit.
The antenna is very important for the wireless module. If the antenna is not connected or the antenna is wrong, it will affect the use effect. The module generally uses 3 types of antennas.
Type 1: Uses single/multi-stranded cables or whip antennas. 315MHz corresponds to 230mm long, 433.92MHz corresponds to 170mm long, with a diameter of 0.5mm to 5mm. When using this antenna, please be careful to spread it out and keep it away from the metal body as much as possible.
Type 2: use spring antenna.
The third type: PCB antenna, we recommend our FTP14 (433MHz) and FTP13 (315MHz), small size and long distance.
Flip mode, each time you press the remote, the corresponding pin state will flip, high and low level cycles.
Auto-lock mode, which is equivalent to the function of 2272L4, keeps the state of the last trigger, and can be pressed in combination with multiple keys
Jog mode, equivalent to the function of 2272M4, output the corresponding output level, when there is no trigger, D0-D3 will turn low.
Latching mode, D0-D3, only one pin can be high at a time, and the other pins are low. Buttons in this mode cannot be pressed in combination
Serial output mode, fixed 9600bps serial port output from the D0 pin to decode the corresponding three bytes, civilized code output 2, such as LC:1234569C \ r \ n,. So the three valid bytes of this string are 0x12,0x34,0x56, and "LC:" is a fixed frame header, 0X9c is a three byte checksum, AND the last \r\n is a newline character exhaust. You can see this string through the serial port wizard. No code matching required in this mode.
