High-quality bare PCB & faceplate for DIYers

This is a bare PCB and faceplate for folks who want to make their own Helium from scratch. You'll need to source all of the components and do all of the assembly yourself. If just you want a complete kit to put together, check out the DIY kit instead. Refer to the self-sourcing build guide for complete instructions.

While you can order boards from any fab, these boards are made according to our extremely high standards: they're made to IPC 6012 Class 2 specifications with 2µ" ENIG plating, high TG substrate, high quality LPI soldermasks, and high resolution DLP silkscreen.
