Too Long; Didn't Read
I already own and use many arm single board computers, regular ones like <a href="https://hackernoon.com/tagged/raspberry-pi" target="_blank">Raspberry Pi</a>, Odroid, Orange Pi and some OpenWrt routers mainly ones using atheros chipset. I favor Raspberry Pi boards for their large community and superior <a href="https://hackernoon.com/tagged/linux" target="_blank">linux</a> and armbian support. However, I have a feeling that current Raspi boards are underpowered and lack useful on-board features like hw buttons or RTC.
