Module No.:YC093
Packing list:
1 pcs 12 V RF  decoder   modules ;
The receiving module using high sensitive superheterodyne receiver circuit, microcontroller decoding, four output channel. Perfect solved the problem of the channel interfere with each other, have hold a key not to put, the other button is still normal and effective operation, which is very suitable for production of wireless intelligent remote control car need more button press, at the same time operating situation. To store various fixed code, learning code remote control. Control mode has the lock, interlock, self-locking three, can be set up.  

Technical parameters:

Working voltage: DC12V (voltage regulator and filter)

Standby current: 6 ma

Working frequency: 315 MHZ

Working principle: the superheterodyne

Modulation mode: baton/ASK

Acuity: - 110 DBM

Decoding formats: microcontroller decoding, kao fixed code, learning code

Output signals: TTL level signal output, four road

PCB size: 40 * 13 * 8 mm

working mode :

solder as shown in:

Momentary - all dissolder 1 and 2 

latch - solder 2

Toogle  -solder 1 

Learning methods: hold down the key learning about 1 second, indicator, press any key indicator lights flashing remote control at this time, said learning success; Can learn more different coding of remote control.

clearing methods: keep pressing  about 20 seconds


Pin definition:

VT :  decoding effective instruction output pin

ABCD:  four control signal output pin

GND:  negative,

ANT:  antenna

 connection diagram : 

Use notice:

1, antenna with soft wire or other hard metal (e.g., telescopic antenna), length of about 28 cm (315 MHZ) or 24 cm (433 MHZ), straight to use as much as possible. Keep away from metal objects.

2, power supply voltage stability and low ripple coefficient, need to multistage filtering (such as increasing magnetic beads, inductance, capacitance, etc.).

3, if used with single chip MCU clock frequency under 4 MHZ and crystal as far as possible away from the RF receive module, or crystal higher harmonic will affect the communication distance.

4, pay attention to the coding and decoding IC IC rate consistent size and format is consistent (namely oscillation resistance to match, the suite of the default of 4.7 M / 820 k), otherwise it will affect the distance and cannot communicate.
