Very nice package. As someone who has recently put together the same thing using a 4b and tiny85 for control/soft shutdown, I can appreciate the hard work that went into this.
Can I ask what you did for dc-dc conversion of std. automotive voltages and whether you have employed protection for DC input by way of discrete components (TVS, polyfuses, etc) or one of them fancy SOP packages that has transient suppression and load dump protection+fusing?
I personally went poly+TVS for simplicity but have only recently added that also to my LED controller.. 5 years and no failures with no protection there but a semi-commercialized product is a different story.
