[IMP] hardware: BlueBus Rev A * Remove TPA6017A2 in favor of PCM5102A Line Level DAC which will fix quality issues * Completely new layout of board and schematic * Update Silkscreen to use vector fonts of consistent sizes * Resize board to 45mm x 70mm from 55mm x 90mm * Update design of transient filter to prevent voltage drops at boot * Add DSP Output SMB connector * Add circuit for mono microphone input * Add 1.5A Littleblock Fuse to prevent over-current * Miter board corners for rounded look

[FIX] hardware: BlueBus v7 * Update Silkscreen for Speaker outputs * Rewire Speaker negative outputs to support single ended operation without overheating * Place 10uF cap for TPA6017A2 near input of 5v so all VDDs can benefit from it * Connect TPA6017A2 N/C pin to GND * Move TPA6017A2 gain resistor * Rewire transient filter for BC127 on the 3.3v rail per application note * Update placement of several passives for alignment * Update passive names to move from bottom right to left, to top right to left * Update Silkscreen with GitHub address

[FIX] firmware_application: Minor Fixes * Fix IO Mappings for EEPROM * Pull up BT Reset pin on boot to ensure no ambiguity * Resize Application Space to start at 0x1000 * Update code to set RPOR Modes via MSB/LSB

Backlink to CADLAB.io has been added.

[IMP] firmware_bootloader: Allow BC127 management * Add code to manage (including FW upgrades) the BC127 module via the system UART * Decrease Bootloader timeout to 5 seconds * Decrease bootloader memory footprint to 1kB * Fix issue causing lag starting the application post firmware write

[FIX] firmware_application: Minor updates * Add ISRs for NVMError and GeneralError traps * Move application code to 0x1800 to allow for larger bootloader * Single partition mode set explicitly

[FIX] firmware_bootloader: Fixes for firmware writing * Enlarge bootloader to 0x1000 bytes * Call application code via void pointer, rather than ASM * Add logic to erase FLASH memory prior to writing it out * Add logic to write out the RESET vector after clearing out the 0x00 page

[FIX] firmware_bootloader: Fixes to allow flash writing * Fix protocol decoding issues * Fix issues sending legitimate messages to the host * Fix issues writing data to flash * Document codebase

[IMP] firmware_bootloader: Add RX Queue timeout * Add 1 second timeout to RX queue to prevent bytes from becoming stuck

[IMP] hardware: Silkscreen / Power rail update * Adjust silkscreen text for PICKIT to locate it below the pins, rather than under * Remove 45 degree angles from 3.3v rail to PIC24 * Remove skew from the VIN wiring near the 100uF cap
