ec500 i/o expander full kit


Available on backorder

SKU: ec500-io-kit Category:


This is a KIT — PCB, panel, and all necessary parts to build the ec500 i/o expander. It is a fairly intricate build, including many surface-mount components, so we don’t recommend this to DIY newcomers. You will not be able to use this by itself; you will also need an ec500 error.core. Build docs are in our github.

The ec500 i/o expander adds a number of new features to the error.core; it also depends on the error.core for power, so you will not be able to use it by itself. Among the features of the i/o expander are:

  • Two line-level inputs with adjustable gain and DC offset
  • An on-board microphone with adjustable gain and DC offset
  • A lighted pushbutton switch
  • An infrared receiver
  • Two triangle-core LFOs with switchable range
  • Three passive attenuators
  • A comparator that is configured to condition triggers from other inputs, but which also has Other Uses
  • A bunch of control voltage sources, some of which round-robin with suitable trigger input
  • A triggerable round-robin for the main R, G, & B busses from the error.core
  • Three AND logic gates
