Serial RFID - Wago Connectors

Hello

I hope you can help me with my question.

I use 4 RFID readers in series on the assembly below

I am new to electronics, and I was wondering if it was possible to connect all the green cables together, the blue ones together, the same for the power supply, then the masses, by means of 5-wire Wago type connectors (4 inputs and one exit). One connector by color.

I understand that's what the breadboard does, but I prefer to check with you before ordering the connectors.

thank you in advance for your help

Well, I suppose you could do that to get rid of the "solderless breadboard".

There are a few problems however.

One is that those boards require conversion of the 5 V UNO logic level to 3.3 V for the MFRC522 devices.

Why would you be using four RFID boards?

You cannot mount them further than perhaps 30 cm or so from the Arduino to work reliably.

Generally, you want to solder connections for reliability and durability.

That should work and would be more reliable than the plug board. I like the fact you have color coded things, makes it much easier to debug. I assume you are also going to wire the other wired directly and eliminate the plug board entirely.

In one of my past lifetimes, Wago wanted me to use their product. I found them unreliable nearly all the time, BUT, my purpose was to make permanent connections robust enough to take years of shaking for hours at a time, not temporary connections that would be replaced by a solder joint. I was told (but never shown) that motorcycle shops use them "all the time." (the cynic in me said: sure... every time one pops open, the shop charge 100 quid just for a look-see).
