4ms SMR

Spectral Multiband Resonator (26HP)

Based on:
SMR by 4ms.

interactive version

A slight redesign of the original 4ms SMR. I rerouted the board with wider tracer and a copper pour, and widened the switch footprints so that solder lugs fit (and added a custom FR-4 panel), but original panels and components will fit just as well.

Build notes

The slider and Lock button LEDs are being driven directly from 3.3V, so depending on the colour you choose they may be quite dim.
