Connect USB pull-up to GPIO PI0_20
This lets the CPU control when to connect to the USB bus, which is
necessary for the boot loader

Replace the regulator with a 3.0V LD2980. Reduce igniter shut-off gap
Switching to a 3.0V regulator and reducing the igniter shut-off gap
both serve to let the board run on significantly lower battery
voltage, down from 3.9V to 3.4V.
The LD2980 doesn't have a bypass pin, so the 470pF cap was
removed.

Move pyro firing pins away from the I2C lines
The I2C pins are open-drain, making them unable to fire igniters. Move
the igniters to PIO0_2 and PIO0_3.

Rotate ballast cap around so GND faces the mounting hole
This should reduce the chances of a mounting screw shorting out the
ballast cap and crow-baring the board.
