433mhz Wireless RF Transmitter & Receiver 5pcs Kit by QCCAN Arduino

Description

Product Overview

The 5‑piece 433 MHz ASK wireless RF transmitter and receiver kit from QCCAN is engineered for developers and hobbyists who need a dependable, low‑cost solution for remote‑control applications. Each module includes a highly integrated superheterodyne transceiver chip, a built‑in low‑noise amplifier, mixers, filters, and a frequency synthesizer, all packed into a compact PCB that measures just 4.37 x 2.05 x 0.55 inches and weighs under one ounce. The design supports a wide operating voltage range of 2.2 V to 5 V, making it compatible with most Arduino boards, ESP32, and other 5 V microcontroller platforms.

Performance‑focused specifications include a receiver sensitivity of –108 dBm, a dynamic range exceeding 60 dB, and a bandwidth of approximately ±150 kHz around the 433.92 MHz carrier frequency. The included antenna is optimized for short‑range communication, delivering reliable signal integrity even in electrically noisy environments. The kit also features ASK and OOK modulation support, allowing developers to choose the most efficient encoding method for their specific use case.

Beyond the core hardware, QCCAN provides comprehensive documentation, example Arduino sketches, and a library that abstracts the low‑level RF handling, enabling rapid prototyping. Whether you are building a wireless power switch, a smart‑home lighting controller, or a remote‑controlled curtain system, this kit offers the flexibility and robustness required for both experimental prototypes and small‑scale production runs.

Designed with durability in mind, the modules are built to withstand temperature variations from –20 °C to +85 °C, and the PCB layout minimizes electromagnetic interference, ensuring consistent operation over extended periods. The kit’s compact form factor also makes it ideal for integration into enclosures, wearable devices, or any space‑constrained project where size and weight are critical considerations.

Usage

This RF kit excels in a variety of real‑world scenarios. In smart‑home installations, it can be paired with relays to create wireless light switches that respond instantly to user commands from a handheld remote or a smartphone app. For DIY enthusiasts, the modules are perfect for building remote‑controlled audio players, motorized blinds, or even simple robot control systems that require reliable, low‑latency communication.

Because the transmitter and receiver operate on the unlicensed 433 MHz ISM band, they are suitable for indoor and outdoor applications where line‑of‑sight communication is required. The low power consumption of the ASK modulation means battery‑operated devices can achieve weeks of operation on a single coin cell, making the kit an excellent choice for portable or battery‑powered projects.

Educators and makers can also leverage the kit in classroom settings to demonstrate fundamental concepts of wireless communication, signal modulation, and RF circuit design. The clear documentation and example code simplify the learning curve, allowing students to focus on creative project development rather than low‑level hardware intricacies.

FAQ

What is the maximum range I can expect from this kit?

Under typical indoor conditions with line‑of‑sight, the modules can reliably communicate up to 30 meters. In open outdoor environments, the range may extend to 100 meters or more, depending on antenna orientation and environmental factors.

Can I use this kit with a microcontroller other than Arduino?

Yes. The transmitter and receiver operate on a 5 V logic level, making them compatible with ESP32, Raspberry Pi (via a level‑shifter), and many other 5 V‑compatible development boards.

Is the ASK modulation suitable for high‑speed data transmission?

ASK is optimized for simple on/off keying and works best for low‑bandwidth control signals such as switches or sensor data. For higher‑speed applications, consider using a different modulation scheme or a dedicated high‑speed transceiver.

Do you provide any example code for integrating the modules with Arduino?

QCCAN offers a downloadable Arduino library that includes example sketches for both transmitter and receiver operation, complete with comments and wiring diagrams to help you get started quickly.

What is the warranty policy for this product?

The kit comes with a one‑year warranty covering manufacturing defects. If you encounter any issues, contact QCCAN support for a replacement or repair, subject to the warranty terms.
