1. Using 5 V control voltage from Arduino
For 5 V systems like Arduino connect Vcc to 5 V and set the JD-VCC jumper.
The inputs are low-active. The microcontroll must deliver a low level to activate the relais.
2. Using 3.3 V control voltage from Raspberry Pi
For 3.3 V systems like Raspberry Pi remove the JD-VCC jumper. Conect 5 V to the JD-VCC side of the jumper.
Connect 3.3 V to VCC.
