Do not apply a voltage higher than 5V to the control pins (IN1, IN2).
Do not reverse the polarity when connecting power to the module.
Do not exceed the specified switching voltages and currents.
Connect power (5V and 0V) to the 1x4 pin header labeled VCC and GND respectively.
Control the relays using 3.3V or 5V logic signals from compatible microcontrollers.
Ensure correct jumper settings for desired trigger mode (high-level or low-level).
