One last update regarding extra part details:
Extra PCB kits (Main PCB, extra daughterboard, and interconnect cable) will be available at 60USD per kit.
Obviously, base kit will include one set of the listed parts.
Extra plates (and corresponding gaskets) will be available in the following variants:
- Aluminum, black (+45USD)
- Polycarbonate, smoky black (+40USD)
- FR4, black (+35USD)
The stock plate included in base kit is aluminum as a very balanced option between sound and feel.
