- screws into a 2.5' drive bay
- controlls power on.off
- usb for virtual ethernet and disk
- access the cpus local serial terminal remotely
setup
after installing ubuntu with the usual usbboot thing:
echo 'dtoverlay=dwc2,dr_mode=peripheral' >> /boot/firmware/config.txt
systemctl stop serial-getty@ttyS0.service
systemctl mask serial-getty@ttyS0.service
systemctl stop systemd-resolved
systemctl disable systemd-resolved
rm /etc/resolv.conf
echo nameserver 8.8.8.8 > /etc/resolv.conf
apt install dnsmasq
systemctl stop dnsmasq
systemctl disable dnsmasqthen install starfeldt bmc and config as:
[power]
switch='gpio5'
[serial]
device='/dev/ttyS0'
[usb]or if you're not a devguard customer maybe look at pikvm.org for a free alternative

Questions
How big is the Lxbmc PCB?
It measures 100 × 69.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lxbmc use?
47 parts, built around the 0826-1X1T-GH-F and G3VM-61G1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lxbmc KiCad files?
From the devguardio/lxbmc repository on GitHub, at the commit this page was made from: the board is hardware/lxbmc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lxbmc design in my own project?
Its repository states no licence, so its author keeps all rights: ask devguardio before reusing the design.
