Can the ordinary IO ports of the RK board be used for the infrared input function?

Yes. For example, the RK3566 development board developed by Dingchang for human body infrared detection has GPIO ports that support the infrared input function. It has a SEN (human body induction) interface (GPIO), which supports the input and output of GPIO and the power output of the SEN (human body induction) infrared module with a power supply of 3.3V. The maximum output current is 500mA.

The human body induction interface can automatically sense the approach and departure of the human body, enabling the RK3566 development board of the unmanned vending machine or visual cabinet to provide an immediate response. That is, it makes the AI commodity recognition algorithm inside the 3566 main control start to work.

The following is the pin definition of this SEN (human body induction) interface (GPIO) provided by the editor of Dingchang for your reference.
