Robot Smart car remote control module / four-button remote control module / wireless remote control

The main parameters of the receiving plate

• Operating Frequency: 3FifteenM
• Operating voltage: DC5V
• Working current: ≤3mA (5.0VDC)
• How it works: super-regenerative
• Modulation: ASK
• Encoding chips: SC2272 (PT2272, PT2294), chip compatible
• Sensitivity: better than -105dBm (50Ω)
• Output signal:Interlock (L) or lock (M) or self-locking (T), the seller before ordering instructions choose which
• Remote distance: 20 to 50 meters (open land)
  Receiver Module seven pins, respectively D3, D2, D1, D0, GND, VT, VCC, where VCC is the supply side of DC5V, GND is a ground terminal, VT terminal to decode the output of valid, as long as the transmitter of data code There output, VT can be synchronized output high; D3, D2, D1, D0 are four data output terminal 2262 decoder chip, can output high of about 5V signal when the drive current of about 2mA, the transmitter The four data code output correspondence. Receiver module can not weld antenna reception signal, in order to improve reception sensitivity, can be a length of about 23 cm of soft wire soldered directly to the antenna hole, referring to FIG RC oscillation resistor, and the transmitter receiver module shock resistance need to match in order to work, I shop receiver module using a 270K or 820K resistors can be 1.5M or 4.7M vibration resistance transmitter supporting the use respectively. The transmitter may use my shop fixed code four-button remote control or transmitter module Quad-band coding, such as supporting the other transmitters, it must provide the transmitter parameters.
