It seems that hardware breakdowns inevitably place a 'raw materials' costing to ojects broken down, often (but less in this instance) - as a somewhat passive-agressive dig at the company: "They sell it for $50, but it's only got $10 worth of components in it!"<p>Outside of the obvious external costs (development, transport, overheads, import, profit, etc), PCB + Tooling costs are often wildly underestimated.<p>For reference, a PCB of this size requires a setup + stencil template, which would run ~ 400 - 500 USD.<p>Tooling for the plastic injection mold for this piece would run around 5000 USD, and each subsequent piece would probably cost around 10 - 50c USD.<p>Tooling + PCBA done right have significant upfront costs that often seem to be forgotten.
