POLY555 Bare PCB
This is the PCB for the POLY555 Synth.
By default, it is only the PCB and has no electronics or other components that would otherwise be included with the full POLY555 DIY Synthesizer Electronics Kit.
This is for advanced users comfortable with electronics, soldering, and sourcing BOMs!
Most of the components are "jelly bean". The exceptions are the specifically sized SPST tactile switches (the buttons under the keys), speaker, and plexiglass. Because they can be annoying to manually source, there's an also an option to include those items with the PCB.

(To save cost, trees, and frustration from outdated information, printed instructions are not included. The online guide will always be up to date!)
Added bonus!: all bare POLY555 PCBs now ship with an attached APC board, for free! Snapping them apart is both fun and very easy to do.
