it's not as expensive as it looks, if you don't count time. CNC alu and the display would be the biggest costs. other carrier board projects use 3d printing over CNC, but the display/bandwidth is kinda what makes this novel so a lower res wouldn't make sense

really hoping Byran's excellent writeup helps encourage others. SoMs have lowered the barrier to entry and birthed a ton of SBC/carrier communities, but most of their tribal knowledge is buried in discord servers
