Additional hardware serial on WAN 1310?

Official Hardware MKR Family MKR WAN 1310

Hello,

I need an additional serial port on my MKR WAN 1310. According to this page ( https://docs.arduino.cc/tutorials/communication/SamdSercom ) I can create additional serial ports.

But I can't find much information about the MKR WAN 1310 specifically. It already has serial communication for the lora module, right? Is there an unused sercomX?

Have you looked at the schematics? Also the datasheet for the SAMD21 chip?

those would show you what's being used, and whether there's any suitable SERCOM pins free...

Serial1 on RX/TX pins?

I added Serial3 on D0/D1 now, it works. I hope it's not used for anything else I'm going to need later.
