Hi forum.  
I'm trying to read the content of a [Grove NFC Module](https://wiki.seeedstudio.com/Grove_NFC/) from a PI4 Using Node-RED (And a [Grove Hat](https://wiki.seeedstudio.com/Grove_Base_Hat_for_Raspberry_Pi/))

The device is talking Serial, and I was expecting to read it using the serial node, but this is not working.  
The node I found are for I2C.

I found [this github](https://github.com/techniq/node-pn532) that is explaining on how to use it via nodejs: how do I translate this to node-red?

thanks in advance for your help
