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. read more : RF 433 MHZ TRANSMITTER AND RECEIVER (WITH DEMO) Video Tutorial: Applications: Remote Controls Automation System Wireless Security System Sensor Reporting Car Security System Remote Keyless Entry

What is the maximum transmission range of the 433MHz RF module?
Up to 100 meters in open line-of-sight conditions; actual range varies with antenna, power supply, and environment.
Can this RF module be used with Arduino or Raspberry Pi?
Yes, compatible with Arduino, ESP32, ESP8266, and Raspberry Pi via digital I/O pins.
Does the module support direct UART communication with a PC?
No, due to high noise levels at 433MHz, direct UART-PC communication is not supported.
What is the operating voltage of the RF transmitter and receiver?
Both modules operate on 5V DC and are not 3.3V tolerant on input pins.
