Hi all,
First post here, I have bought a Arduino Uno R4 WiFi but I want to add an expansion board I think you call it that plugs into the main board and then the expasion board allows you to use screw terminals for my connections to my CNC.
I have found several that say they fit the Uno R3 but not my actual board, will the R3 version work with mine or is it specific to the boards?

Hi Lee,
Welcome to the play ground.
It all depends on if the number of pins on both boards, the pin functions the pin spacing match. I have downed both the boards specs on. It’s a hasle doing it on a mobile, switching between them so I’ll post them here where they can be set to show side by side.
Now lets have a look at them and find out how likely it is both the boards will fit the connector board.
Edit after review.
Looks like your good to go on pin function and pin placement. I think the pin spacing will be good too, but am not 100 points sure. Possibly you need to add a external on/off switch on the R4, but that does not interfere with the connection board.
Hi Eddie, thank you very much for taking the time to help me out, as you can probably tell this is all new to me, Iam keen to learn but electronics and programing are not my strong points.
Hi Lee,
For someone who does not feel comfy with electronics ‘n’ programming, you surely are taking on a challenge.
I take my hat off for people who take the route of their weakness to come out stronger no matter if the goal will be reached. I also have that one question jumping on the tip of my tongue.
Why?
Edit to rephrase the question.
What machine are you going to connect to this arduino contraption. Are there not more out of the box solutions available?
Pleaseplease elaborate more on what you are doing. I’m intriged.
I am making my home built CNC machine and I think I’d like to use GSender software and it seems people use Arduino to run it, I already have external drivers for the stepper motors so I don’t think I need to use a CNC shield board, but could be completely wrong.
That looks badass! Love the “watch your head” red color you have going.
As it is wholy possible to go the arduino route, gsender can run a multitude of controler boards that are a lot less electronicy/programmy to get going including sienci’s 32bit SLB unit that hounts me in my dreams.
If you get stuck going the path you have choosen. You can always come here for support. But know that getting stuck on this controller part, is by no means a game stopper. And that is always nice to know.
Please keep us informed on your progress. Custom build cnc machines, and their creators, are awesome.
