vr6syncro / RGBWW Controller - History

updated Gerber Files and Pictures

exported Gerber Files, shot a few new pictures of the board.
Unlike the Beta Boards, this version does not have pads for an R/C snubber as I don't think it will be necessary. Also, there's a larger GND area covering the top layer input side of the circuit and the 3V3 area around C1 has been expanded..
The TXD and RXD pins have switched places, it was easier to route them like that and also, their location now crosses over with the usual USB/UART converters (straight cable run).
On the disable jumper location, the pins have also switched places, disable is now on the top, pointing away from C3

yet more minor changes on the input side

removed the snubber pads
created a lower impedance GND path
swiched RXD and TXD for some more elegant routing and better fit with the usual USB/UART connectors (straight cable now switches RX/TX)
minor silkscreen corrections for better legibility

more board improvements

- floodfills for VCC, PH and top layer +3V3 nods
- RC snubber for PH node
- additional 10nF cap close to the ESPs 3.3V
- cleaned up the GND layer a bit

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
