MCU decode super regeneration RF receiver Module

MCU decode super regeneration RF receiver Module
Product Detailed
RF receiver Module 1. Voltage: 5.0V 2. Current: 5.5mA 3. Sensitivity: -105dBm 4. 2Mhz bandwidth

Model No.: DL-R40BR

Description: MCU decode super regeneration RF receiver Module

Product Detail:

DL-R40BR rolling code receiving module adopts the most advanced RF integrated circuit and extremely reliable KEELOQ encrypted arithmetic, DL-R40BR is a rolling code receiving module with perfect performance. Its circuit is designed innovatively and stably. This module is widely applied in some condition that has high requirement at security. It has decoding IC, so it can work independently.

 

Application:

a. Wireless remote control system for garage gate;

b. Various anti-theft system control

c. Gate security system

d. Other wireless remote control

Size and Pin definition

 

Learning code instruction:

a. Learning ID: Press the Learn button then release, when the LED is on, that means it is now in the learning state. The LED will flash after learning is over. The LED will keep on till to next remote control learning operation. If remote control has learned the code already, the module will automatically exit learning state. The module will automatically exit learning state if no operation within 10 seconds.

b. Deleting ID: Keep pressing the learn button, after 5 seconds, the LED will be on and the module is at deleting state. When the LED is off, it means the deleting operation is over.

 

Notes for usage

a. Pls use soft lead wire or other hard metal (like telescopic antenna), It can not be either too long or too short, or it will affect the receiving distance. The antenna should be stretched as straight as possible if it is using soft lead wire, and as far as possible from the metal objects.

b. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)

Garantee: 13 months !

Lead time: 

   1. Samples: 3-5 working days after receive the payment;

   2. Order: 10-15 working days after receive the payment;

                                   

Shipment: 

We deliver by EMS, DHL, UPS, TNT, FedEx, Hongkong Post, Singapore Post and so on at the first reasonable time.

*EMS usually takes about 6-13 days, more or less. For far region or custom reason, it will take a little longer time, pls be patient;

*DHL, UPS, TNE, FedEx usually takes about 4-6 days, For far region or custom reason, it will take a little longer time, pls be patient;

*Hong kong post, Singapore post usually takes about 10-15 days, For far region or custom reason, it will take a little longer time, pls be patient;

*We usually show very low price, so the buyer can avoid paying the tax. However, the tax is determined by the custom of the destination, not by us, different countries have different tax rate, so if any tax, then the buyer should undertake it. If you have any special requrement, pls let us know before the order.

*We will not responsible for any loss due to the buyer's reason, including"refuse to sign the package" or "refuse to pay the tax" or "destination country post reason". We are in charge of delivering the goods in good condition, once the express carrier sign the airway bill, we will not be in charge of any responsibility.
