## Errata
- revision 1.0:
- The reverse polarity protection diodes `D201` and `D202` are 180° wrong in the pick and place file, but not on the silkscreen, resulting in no operation when the power connector is connected the right way and destructive operation when the connector is connected the wrong way. Fix by flipping the two diodes 180° to their true orientation as indicated by the silkscreen (or bridge the pads, which would result into a loss of reverse polarity protection, but would still work).
- The "universal footprint" for the switch turns out to be not all that useful, you still need to get 1.27 mm lead spaced On-Off-On toggle switches, which are much harder to find. I am not sure if this can be fixed in the next revision because there is not much space for bigger footprints.
- Some of the TH-solder joints are close to SMD parts and could thus result in destructive action by inexperienced solderers, where possible they will be moved
- 1.5k for `R207` might be too much, maybe a value of 1k would be better suited to allow true 1 V/Oct tracking
Errors can always happen, gladly this time they were only very minor ones
