GPIO Addressable LED Indicators
This pcb can read 8 digital inputs and display their high/low state on one of 8 addressable LEDs as a fast indicator.
This is useful when a bunch of LEDs are needed for a project and it would be inconvenient to breadboard separate LEDs.
An ATTiny804 is used to control 8 SK6812 mini LEDs, based on 8 digital input states on a header.
The board operates at 5v
The 8 inputs have a FET level shifter and a separate VCC power pin so they can run at 3.3v or 5v, based on the VCC pin voltage.
There is a config jumper and a button to switch between modes, so the LEDs can show green/red or green/off when the corresponding input is high/low, or whatever a sketch is set up to display as inputs change.
