add pull-downs on large mosfet gates, tons of silkscreen tidying including labelling of signals in connectors and power routing indicators
UART voltage selector- add trace to select 5v by default, user must cut trace to select 3.3v
ensure all connectors include a 3.5mm footprint, remove 0.1" footprint from high current connector, minor routing updates
add solder pads for JTAG- not enough room to route a proper connector
