UD3.1c

Yay release time :)

I've added a few more circuit improvements over the UD3.1a&b variants, but here's a list of all changes since the base version UD3 since the previous UD3.1 iterations didn't get a proper release:

• LED outputs are now open drain, allowing use of 24V indicators
• Voltage sense amplifiers moved to single 5V rail
• Updated gate drive structure to allow more wide range of N&P Fet combo packages
• Added protection resistors to Relay and LED pins, added protections resistors in series with mosfet gates
• Added buck regulator for VDrive, adjustable between 10V-24V
• Added more indicator LEDs for debug purposes
• Added supply voltages to more expansion headers, external gate header can now directly support 24V gate driver modules
• The Design can now be almost entirely built with the JLC assmebly service. Only the psoc needs to be hand soldered.
• 5V regulator changed to smd from the external regulator module, to further reduce the hand-assembly component count

WORD OF WARNING
The BOM and Pick&Place files might well have some wrong part numbers in there. I tried my best to double check everything but there might still be some wrong ones in there, so DOUBLE CHECK EVERYTHING BEFORE ORDERING 😄
The Orientation in the Pick&Place files is also wrong on some parts, so you will need to rotate them when ordering with assembly.
