Peter Jakobs / RGBWW Controller - History

some power supply improvements

added a snubber network to PH (140MHz) plus a 10nF cap on the +3V3 line
Added low impedance floodfills for +3V3 and PH where applicable
switched the location of the RST and PRG switches since it seems easier to have the RST on the outside

added enable function

I added a pin header to short the TPS5410's ENABLE pin to GND, thus switching off the DC/DC converter, effectively turning the controller completely off.
The controller should function normally, when this is left open. Including a switch that connects those two pins is a way of switching the controller off without disconnecting the 12V supply. Whatever it'll be good for.

added BOM

BOM

updated silk screen

some minor changes, mostly cleaned up silk screen

another reduction in size

replaced most of the power supply parts, shaved off another 3mm

new, smaller board

new design, integrated DCDC converter, new, smaller MOSFETs, smaller overal board, additional PRG button, mostly optimized for SMD manufacturing but still hand solderable
