Alright, the schematics and PCB are done and I drew in parts that I already have hoarded over the years so there's gonna be a mix of parts with packages ranging from SOT-23 all the way to BGA which I'll be assembling by hand so we'll how this will pan out. 

The buck regulator for LEDs will be a particularly tricky one both in terms of assembly and making it work since its this wacky dual phase topology which is new for me so looking forward to exploring new avenues of power design..

Oh and controlling the voltage of the regulator using a digi-pot also is an intriguing topic in itself..

So yes, the LEDs will basically be connected in parallel from the high-current 2.5V-3V adjustible voltage bus. That should make the LED segment driving way easier.. or..will bring some issues with unintentional LED dimming during heavy current load..
