Changes

• Make the led’s sequential

  • HW implemenation covered in Lights Research MSXV

  • Software solution is another possibility

• Add reverse polarity protection with pnp (shouldn’t need the clamp part)

• Potentially upgrade current mirror to Wilson/Full wilson Chapter 11: The Current Mirror [Analog Devices Wiki]

• Maybe add in some thermal vias (probably not necessary thermal performance was fine)

• Potentially add some test points for ease of validation/debugging
