t3ddftw / BlueBus - History

[ADD] firmware: Production Updates
* Disable ADC for used ports
* Remove Prototype board mappings
* Remove system.c after merging it into main.c
* Remove calls to disable ADC on EEPROM ports, since this is handled en-mass

[ADD] hardware: BlueBus BOM Updates
* Add GitHub link to Silkscreen
* Update Embedded BOM

[ADD] hardware: BlueBus v5 updates
* Remove external crystals
* Add pull up resistors to MCLR -- Bug in existing boards causing unstable operation
* Rewire BC127 UART lines to MCU

[ADD] firmware: Production board updates
* Update pin configurations
* Add Prototype board configurations for pins in comments
* Remove external crystal configuration and use FRC instead
* Use PICKIT4
* Update Configuration to use GA606 device

[ADD] hardware: BlueBus Board rev. 5
* Add primary 8MHz oscillator
* Wire EEPROM signals to compatible pins
* Rewire all capacitors so they are not inline with the power rail (Mostly on MCU)
* Update pins style to common size instead of the long pin pads
* Update size and location of mounting holes
* Rewire VIN to make room for mounting holes

[ADD] hardware: Power Management Updates
* Wire 5v regulator FB pin to GND
* Update BS Cap to 0.01uf from 0.1uf per the datasheet
* Add 100kohm resistor to EN pin of 5v regulator
* Rewire VIN and 5v Regulator
* Update 0.1uF cap on VIN of 3.3v LDO to 1uF per the datasheet
* Update 0.1uF cap on VOUT of 3.3v LDO to 2.2uF per the datasheet (>1.0uF required)
* Rewire Power Signals so they make more sense

[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
