From what I can tell, the xeno board looks larger, so I think my main question is if there are any electronics incompatibilities such as with a xeno’s neopixel blade? Soldering isn’t an issue, been doing that since [sobs in feeling old].
Short answer is that I have no idea, but it’s likely that they use fairly standard switches, leds and wiring, which would make a proffieboard work just fine.
Yeah I have a AusSaber and the internals are the same chassis. My incendius comes with both proffie and xenopixel. In fact you can buy the proffie kit from Vire Sabers for 115 and you don’t need to solder it.
