Hey all!
I received my X4 yesterday and have given my initial thoughts on the board (and the PoE HAT/cooler) at https://bret.dk/intel-n100-radxa-x4-first-thoughts/
If you have any questions, or specific things you’d like me to take a look at, let me know and I’ll do my best

Would you be interested in trying Android x86? I’m curious as to the N100 temperature when running android.
It’s not something I really have experience with but if you can point me in the right direction of an image/installation then I can see if I can squeeze it in at some point!
Nice review, it seems like the bottom cooler isn’t ideal for working with hats in the end…
What have you tried to do with gpio ?
Just toggle on/off or PWM/Serial interfaces ?
If you haven’t, could you try sending UART/I2C frames over the gpio ?
Thanks again for the initial review !
Will look into it at some point this week hopefully. It’s a bit hectic at home at the moment!
I’ve not actually tried anything yet, I’ve had a quick look to see how I’d interact with it but I didn’t see it as a super critical part for my first review. I’ll get to it in followup pieces though and will take a look.
Okay good to know, thank you,
I’ll stay tuned for your next work then.
Have a good week!
