RF 433 MHz Transmitter & Receiver Module (Only RF)



This hybrid RF Module (Transceiver) module provides a complete RF transmitter and receiver module solution which can be used to transmit data at up to 3 KHz from any standard CMOS/TTL source.
The transmitter module is very simple to operate and offers low current consumption (typical. 11mA). Data can be supplied directly from a microprocessor or encoding device, thus keeping the component count down and ensuring a low hardware cost.

The RX – ASK is an ASK Hybrid receiver module. It is an effective low-cost solution for using 433 Mhz. The TX-ASK is an ASK hybrid transmitter module. TX-ASK is designed by the saw resonator, with an effective low cost, small size and simple to use for designing.

Please note that this device will not support direct UART communication when connected to PC or microcontrollers as there is a lot of noise always available on these frequencies.
