t3ddftw / BlueBus - History

[ADD] hardware: BT_UART I/O Change
* Re-wire BT_UART for FTDI cable compatability

[ADD] hardware: Minor board changes
* Add mounting holes
* Fix uneven pitch of crystal caps
* Replace wide through-hole pins with standard sized ones
* Update name of TPA6017A2 IC
* Update trace widths for 5v rail to .55mm

[IMP] hardware: Remove EAGLE board revision from VCS

[ADD] hardware: BlueBus v4 Board Changes
* Remove BC127 LEDs
* Enlarge all IC pads to make SMD assembly easier
* Rewire 3.3v Rail into a star topology to do away with potential issues from dasiy chaining
* Rewire portions of the 5V rail
* Rewire MIC_IN Signals to make use of stereo audio
* Tighten up similar signals for better board routing
* Enlarge all vias to 0.51mm
* Elarge 5v rail to 0.55mm
* Tent all vias for a nicer silkscreen
* Update silkscreen positioning
* Remove wires from under TPA6013 since it contains a thermal pad

[ADD] hardware: Update Schematic and Board
* Remove local libraries that can be found by EAGLE automatically
* Rewire VIN side of the board
* Update D4 to be a 30V 2A Diode, instead of a 100V 250mA diode

[IMP] hardware: Add Diode to 5V USB Input
* Add diode to prevent voltage oopsies in case someone plugs > 5VDC to the rail

[IMP] hardware: Minor updates to design
* Increase trace size to 0.22mm minimum
* Increase all power traces to .5mm minimum
* Add silkscreen goodies and name parts directly on PCB
* Ensure all nets are named aptly

[IMP] hardware: Finalize Schematic & Rev 1 board
* Finish Schematic
* Finalize board layout for rev 1 board
