RF Wireless Module Pair (433MHZ)

DC 5V 433Mhz RF Wireless Transmitter Module and Receiver Kit

The TX-ASK is an effective low-cost solution for using the 433 MHz frequency. This ASK hybrid transmitter module is designed with a saw resonator, making it small, cost-effective, and easy to use for designing. However, it’s important to note that this 433mhz rf transmitter and receiver kit does not support direct UART communication when connected to PCs or microcontrollers due to the high levels of noise on these frequencies.

The RF module comprises a 433mhz rf transmitter and receiver. The transmitter receives serial data and wirelessly transmits it through RF via its antenna connected at pin4. The transmission rate can be set to 1kbps or 10kbps. The transmitted data is received by an RF receiver operating at the same frequency as the transmitter. This 433 MHz RF transmitter and receiver pair is cost-effective and can transmit signals up to 100 meters (although the antenna design, working environment, and supply voltage will significantly impact the effective distance). It's ideal for short-distance battery-powered device development.
