R4 WIFI physical pin layout

Official Hardware UNO Family UNO R4 WiFi

Hi everyone,

I'm currently designing a PCB that will sit beneath an Arduino R4 WiFi using male pin headers to connect the two. I need the exact physical layout measurements of the Arduino R4 WIFI, including the distances between the pins and their arrangement on the board. Unfortunately, I wasn't been able to find information in the datasheet that includes these specific measurements.

Does anyone know where I can find a physical layout diagram for the Arduino R4 WIFI? Alternatively, if you’ve already designed a similar PCB (using EasyEDA), I’d appreciate any tips or resources you could share!

Thanks in advance for your help!

Welcome to the forum

Which PCB design program are you using ?

The footprint of the R4 WiFi is the same as the classic Nano

3

Thanks, I'm using EasyEDA.

It almost certainly has a footprint for the classic Nano

5

Yes it does

6

Are you sure?
It seems like they have totally different dimensions

Sorry !

What I meant to say was that the Uno R4 has the same pinout at the classic Uno and I am sure that EasyEDA will have a footprint for that

Thanks for the clarification!

I have another question:
I’m planning to place male pin headers on my PCB. Are there specific types of pin headers I should consider?
For example, should I pay attention to factors like pin-to-pin spacing, resistance, or capacitance?

Thanks in advance!

That's not possible since the female headers are on TOP

What do you mean by that?
The female headers sit on the top of the Arduino UNO R4.
But I can flip the PCB so it'll be like a sandwich.

What do you mean by that?

Depends what you consider to be top and bottom. The side of the R4 with the headers is normally considered to be the TOP.

But I can flip the PCB so it'll be like a sandwich.

That could be tricky since you will now have components facing components and determining clearances could be difficult.
