433 RX-TX Module

We’re The First 433-RX-TX Module Manufacturer In INDIA

For Product enquiry Kindly Contact Us.

RX433 is an ASK/OOK receiver super-heterodyne module, which is designed specifically for universal remote control and wireless security receiver operating at 433.92MHz under FCC Part 15 regulation or pass ETSI certification. The RX433 is based on a single-conversion, superheterodyne receiver architecture and incorporates an entire Phase-Locked Loop (PLL) for precise local oscillator generation. It can be used in OOK/HCS/ PWM modulation signal and demodulate to a digital signal.

RX433 is a high-performance module at a competitive cost and easy to design for your product. The RX433 module can be also a RoHS compliance product.

Type: ASK Transmitter Module

Model: TX433

DESCRIPTION:

TX433 is an ASK radio transmitter module. This module is a superior performance transmitter module for the ISM band. With the adoption of European brand RF wireless data transferring/ receiver chipsets, it has an advantage at strong transmission power, low voltage power supply, easily through the Fcc/CE authentication. It can do wireless signal input to the data signal output without any external circuit. Users only need to decode the data plus a simple circuit and then any wireless product development can be easily achieved.
