 # WS2812B light signal - CPU Board
-
-Board to run [colorchord2](https://github.com/cnlohr/colorchord) on a string of WS2812B LEDs with live line-in audio.

-## Errata (Rev 01)
-
-* Opamp inverting / non-inverting inputs are swapped
-	* Workaround: Lift pads 2 and 3, and 5 and 6, and connect them crossed using magnet wire.
-* Opamp is not rail-to-rail and does not allow to use the ADC in full range
-	* Workaround: Only use limited range -640 to 520.
-* LED footprint is wrong.
-	* Workaround: Flip 180 degrees and solder shifted onto the right pads, then use magnet wire to connect the remaining two pads.
-* Serial boot loader non-functional (uses incompatible UART I/Os).
-	* Workaround: Program via JTAG / SWD.
