Dear sir, i am making 4-channel relay board . but during making i have a problem with capacitor (like which type of capacitor is ? and how many volts ?). i want to know the capacitor detail used in 4-channel relay board .plz help me…

Nicos Karalis

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

Ravi Ravnang

Hi,please provide the Gerber file

usaid

Sir can i use 5v relay instead of 12v with the same

smit

there is no connection detail for vcc and gnd for any nodemacu or arduino connection

amin

which software you have used

Karthi

How to connect the board to arduino uno.
No details for VCC and gnd for any arduino boards
How to connect the relay board with 12 v connection and then with the arduino uno.
Pls help me out.

Sir,,what if we want to build,some like this,but used relay,,anyway i need the out put is lamp and bell,,but,just one switch may turn on first and the other is off..it seems like quiz..please made some like that.Thanks

Tyralee

sir can i ask, what is that SIP6, and CN?

Hasmukh Goswami

Sir please tell me I won’t to operate this pcb in 12v but after give supply then S1s2s3s4 which link I give GND ro +v

Hasmukh Goswami

Sir this circuit 24 hor going to work but I won’t to ask you there is possible to work
