DC3V-5V 433MHZ RF Wireless Remote Control Switch Receiver Module with 2 Button Controller
Description:
100% brand new and high quality
Feature:
The power supply of the control panel is 3v-5v, which is especially suitable for the digital lithium battery power supply (the battery voltage of the mobile phone is generally 3.7v-4.2v).
The measured static working current is about 3.5mA when the DC4.2V is powered, and the working current when the relay is closed is about 70mA.
Benefits of relay output: provide isolated contact switch, which can control on / off of signal line, modification of mechanical button switch, etc., and on / off of 3V-5V power supply.
Relay: large brand relay, durable and non heating.
Crystal oscillator: more precise crystal oscillator transforms electric energy into more stable signal.
Work indicator: the work status is clear at a glance.
Learn button: operate the button shell to add or delete the remote control.
Antenna: it can be straightened for use. After stretching, the signal will be more stable and the effect will be better.
Decoding chip: high quality independent decoding chip, making response faster and error lower.
Application: access control digital products, model toys and other small power applications.
