Hi.
oki, in case i'll add some explanation.. I'll be busy for this week but you can simply use the serial gw example from MySensors for getting started, this should work. I didn't need to create a special board in arduino for this board, so if you're using it, you'll need to install&use the mattairtech SAMD21 board definition for the pin mapping.

Sure, there is already the KiCAD file including everything to play around with on your own; added a picture of the schematic here for a quick glance without downloading.
Hey vivek101
how did you connect the NRF24L01 to your home assistant server? Normaly, you connect the nRF to an microcontroller and flash it with a gateway sketch. Then you connect the uC to your server...

Hi,
I finally received the boards from the manufacturer(big thanks to @Seeed-Fusion). I manage to assemble one board by soldering the components and such and...it WORKS(including OTA)! I will post the instructions on openhardware.io project page.
