RF

The 433MHz RF Transmitter and Receiver module provides a reliable and cost-effective solution for wireless communication in a wide range of DIY and professional projects. This paired set enables radio frequency (RF) communication between two devices, such as an Arduino, NULA or other microcontrollers, making it perfect for applications requiring remote control or data exchange without physical wiring. Its design ensures stable performance, while the ease of integration allows both beginners and experienced makers to quickly implement wireless functionalities.

Designed with versatility in mind, this RF module operates at a frequency of 433MHz, a widely accepted band for short-range wireless applications. It utilizes ASK (Amplitude Shift Keying) modulation, offering a balance between simplicity and effective data transmission. The module’s flexible voltage requirements for the transmitter (3V – 12V) allow for adjustable range, reaching up to 40 meters indoors and an impressive 100 meters outdoors, especially when paired with an external antenna. This makes it suitable for home automation, security systems, and various Internet of Things (IoT) devices.

Backed by documentation, tutorials and open-source software compatibility (e.g., Arduino RadioHead library), they provide an accessible path for both beginners and experienced developers to add wireless capability to projects.

Connecting the NRF24L01 can be tricky – you have to pay attention to the layout of the pins, adjust them to match those from the library and add a capacitor. This board solves all that, and it already comes with soldered headers, so just plug this board into your Dasduino and that’s it!

• Dimensions: 38 x 22 mm

443MHz RF is an accessible and affordable standard for RF communication between two devices (e.g. two Dasduino boards or between a remote controller and Dasduino with receiver) often used for remote control, wireless communication and data transmission. With this remote, commands are sent at 433MHz frequency and it’s able to send 4 different commands in total.

443MHz RF is an accessible and affordable standard for RF communication between two devices (e.g. two Dasduino boards or between a remote controller and Dasduino with receiver) often used for remote control, wireless communication and data transmission. This combination allows you to communicate with a remote control that has four buttons with one receiver.

This antenna is designed for 433MHz modules from our offer and improves their range even up to 300%. It works both as a receiver and as an emitter.
