'''WARNING:''' do not directly connect signals with a voltage greater than 3.3V to the controller's GPIO! If you need to connect a device that produces a signal with a higher voltage, use matching circuits. In some cases, if the signal voltage is not more than 5 V, then it is possible to match the signals through a 20 kΩ resistor. | '''WARNING:''' do not directly connect signals with a voltage greater than 3.3V to the controller's GPIO!
