315Mhz RF Remote Transmitter – Arduino Compatible

This is a two-channel RF Transmitter unit that consists of, Atmega328 microcontroller, 2 Tactile switches with pull-down resistors, a programming port, and a 315Mhz RF transmitter module. It is an Arduino compatible open-source project that can be used for many RF transmitter applications. It is advisable to use 1 Foot hook-up wire as Antenna to enjoy a maximum range of the transmitter.

Arduino Pins: D3, D4 Tactile Switch and D12 data out for AM transmitter

Features

• Supply 5V DC @ 20mA
• 2 Tactile Switches with Pulldown Resistors
• PCB Dimensions 52.71 x 28.26mm

Applications

RF Remote ON/OFF AC or DC loads like, Fans, Lights, Home Appliances, Door control. This transmitter is compatible with 315Mhz RF Remote Receiver with On-Board Relay.

Arduino Code

Arduino Code is provided as a download The code works with single SW1, it toggles the Receiver Relay when the switch is pressed. A new Atmega328 chip requires Bootloader and Arduino firmware programming. Please, check the link below to learn more about programming the new Atmega328. Transmitter PCB has an onboard programming port.
