      If you are reffering to C1, then a simple ceramic capacitor will do it’s job.

  • Can you explain why the capacitors? I found no relay module on the market that uses a capacitor.What is the need for it?

      The capacitors are used for noise filtering of the power supply. If you use a filtered power supply you may omit them.
