RF Transmitting Module - 433Mhz

RF Transmitting Module - 433Mhz - If you need a wireless connection when wifi and BlueTooth are not available, this module won't fail you. This has consisted of a transmitter and receiver, communicating at 433 MHz. One popular use of this module is for sending remote control commands. This is a module for one-way sending only. It can't be used for sending and receiving as they have different modules.



  • Frequency: 433Mhz
  • Modulation: ASK
  • Receiver Data Output: High - 1/2 Vcc, Low - 0.7v
  • Transmitter Input Voltage: 3-12V (high voltage = more transmitting power)

433 MHz RF Transmitter Module – Description

The RF Transmitter/Receiver (433 MHz) module is an excellent tool to create connections wirelessly in the absence of Bluetooth and Wi-Fi. It is an FS1000A transmitter RF Radio unit that integrates an RF transmitter and an RF receiver. Both these modules are proposed to bring paring at a frequency of 433 MHz. Hence, it is an efficient development to help those who desire to capture uninterrupted data communication between two modules.

Further, an RF transmitter integrated into the unit receives serial data and pushes it further wirelessly through an RF antenna that is associated with PIN4. When it comes to elaborating on the speed of the transmission of data, it can reach 1kbps to 10kbps. On the other side, there is an RF receiver to receive the transmitted data at the same frequency. This receiving end is critically implemented to capture transmitted data and present it in understandable code.

As far as the distance is concerned, the low-cost RF transmitter is capable of delivering signals up to 100 meters. However, there are several factors that can affect data transmission in terms of distance. The distance can get impacted vigorously by the antenna design, supply voltage, and working environment. Ultimately, the RF Transmitter Module is an ideal weapon to transmit data across short distances and battery power device development. Both the transmitter and receiver operate at a frequency of 433 MHz.

Pinout for the 433MHz RF Transmitter & Receiver Module
It is another crucial element you need to emphasize for better execution. The following is the system of the pinout of the module:

Basically, there are 4 types of pins found on the chip:
  • DATA: This pin is tasked to accept data to be transmitted.
  • VCC: This pin supplies power for the transmitter. It can bring any positive DC voltage between 3.5V and 12V.
  • GND: It is a Ground pin.
  • Antenna: This pin is dedicated to an external antenna.

Integrating Arduino with 433MHz RF Transmitter Module

Impeccably, the 433MHz RF Transmitter Module can also be used to share data/messages between two Arduino boards.You can connect the RF transmitter to an Arduino board and then it will send the “Hello World!” message. On the other side, there will be another Arduino board to receive the message.

Parts needed:

To execute the process, you will arrange for the following components:
  • 2 Arduino boards
  • A 433MHz RF Transmitter Module
  • Jumper Wires
  • Breadboard
