Hi! I have exactly this relay module: [HTB18wrzgZIrBKNjSZK9q6ygoVXar] but it is different from the conventional ones from what I see. I can't find where to connect the digital pin because there is no inscription in the module and searching on I can't find it. Could someone tell me? Sorry for the…

That is for an ESP01 module. Use a meter to trace the pins.

Thanks!
