What is IR2IO?

It's a very simple 4-channel switch, controllable by any infrared remote control. You don't need to know anything about the protocol or frequency of your remote control - the IR2IO board works with any common IR-remote control. This is the easiest way to control your hardware by an infrared remote control.

Implementing an infrared protocol on your controller project is not so easy (you have to know some information about your remote control like frequency and type of protocol and finally you have to find a library for this which runs on your microcontroller). Most projects only need to react on some few specific buttons of your infrared remote control - save your time and nerves and concentrate on the main parts of your project. You can now control your hardware with any IR-remote control in just few seconds.

To cover a wide range of use cases - the IR2IO has a very wide input voltage range: Any supply voltage from 3,3V to 24V can be used.

How does it work?

The IR2IO Board has an broadband IR-Receiver. It can works with all infrared signals with a base frequency between 20kHz and 60kHz. This covers all common used infrared frequencies used in IR-remote controls. To couple a button on your IR-remote control with one of the 4 outputs of the IR2IO, just press and hold the to the output corresponding button on the IR2IO board and then press the button on your remote control which you want to couple with this output. Thats all! Now the Output is coupled with this button on your remote control - anytime you press the button on your controler - the output will get active as long as you press and hold the button.

Configurable

IR2IO supports 3 modes: - Normal mode: This is the default mode - the output is active as long as you press the button on your remote control. - Inverting Mode: The outputs are switching against ground. This is the best way to switch loads like an relais. But if you measure the voltage at the output - you will measure a high level if the switch is inactive and a low level if the switch is active. If you want you can change this by activating the invert-mode. This is needed if you want connect directly e.g. a motorcontroler which reacts on high-levels. - Toggle Mode: If you activate this mode, the output will stay active also after releasing the button on your remote control. Only when you press the button a second time, the output will get inactive.

For more details, how to enable/disable this modes, see video or manual.

Technical Data

*Onboard LEDs will only work with Voltage ≥ 5V. Nevertheless full functionality is given with 3,3 V supply, except LEDs.
