ready to send out for more proto boards
fix SPI vs I2C conflict, adjust copper, get board DRC clean
move serial number silk rectangle and traces so laser engraving is safe
change I2C pullups to 2.49k, saves a resistor value
forward annotate metadata to pcb
clean up copper a bit for new resistor
Add USB pull-up on PA8 The STM31F103 doesn't have any built-in USB pull up mechanism, so we need to burn a GPIO. Use PA8 as that was reasonably close on the board and available. Signed-off-by: Keith Packard <keithp@keithp.com>
add 'p1' to the silk for proto run
improve copper and silk
more tweaking
route complete, copper improved
route complete
work in progress, 9 rats remain
schematic presumed complete, work in progress on layout
eliminate shorts due to template upgrade sequencing
move pcb artwork to latest pcb-rnd template for layers, etc
increase size of polarity markings around LiPo connector
update layout to include new 11071 USB connector footprint
snapshot work in progress
forward-annotated new 4ucon micro USB connector to the pcb design
