The 433Mhz RF Transmitter and Receiver by Satkit is a module designed to make wireless communication easier in electronic projects, especially those compatible with Arduino platforms. This device operates at the standard 433Mhz frequency, using ASK modulation to transmit and receive signals efficiently.
Main features:
- Frequency: 433Mhz, ideal for short- and medium-range radio frequency applications.
- Modulation: ASK, which allows clear and stable data transmission.
- Receiver data output: High level at 1/2 Vcc and low level at 0.7V, making integration with microcontrollers easier.
- Transmitter input voltage: Between 3 and 12V, with a higher voltage increasing transmission power.
Common uses:
- Arduino projects that require simple and affordable wireless communication.
- Remote control and automation systems.
- Data transmission between electronic devices without cables.
Compatibility: This module is compatible with most Arduino boards and other microcontrollers that support digital input and output signals. Its easy integration makes it ideal for developers and electronics hobbyists.

Customer Questions & Answers
What maximum transmission distance can be expected under normal conditions and which factors affect this range?
Under ideal conditions and with a suitable antenna, the range can be 30-50 m indoors and up to 100 m outdoors in open areas. Obstacles such as walls, interference from other equipment and antenna quality significantly affect the real range. Transmission power also depends on the input voltage at the transmitter.
What does the product physically include and what are the approximate dimensions and weight of each module?
The set includes an RF transmitter and receiver with pins for standard connection. Typical dimensions: transmitter 19 x 19 mm, receiver 30 x 14 mm. Approximate individual weight: 2-3 g. Antennas are not usually included in the box; it is recommended to use 17 cm wires as an antenna for the 433 MHz frequency.
Are there any interference limitations or common issues, and how can they be minimised when designing an application with these modules?
The main limitation is interference from other devices operating at 433 MHz, as well as possible noise from nearby sources. To minimise problems, it is recommended to use power supply filters, a well-tuned antenna and to keep a reasonable distance from interference sources. Implementing software encoding helps reduce transmission errors.
What is the 433Mhz RF transmitter and receiver used for?
It is used to transmit and receive wireless signals in electronic projects, especially with Arduino, making cable-free communication easier.
Is it compatible with Arduino?
Yes, this module is compatible with most Arduino boards and microcontrollers that accept digital signals.
What is the transmitter voltage range?
The transmitter works with an input voltage between 3 and 12 volts, with a higher voltage increasing transmission power.
