Andrew Tridgell ed58758ce6 hwdef: don't use DEFAULTGPIO in bootloaders 
setting up a DEFAULTGPIO pulldown in bootloaders is a bad idea as it
overrides any hardware pullups that have been put in place as part of
a "hold in bootloader" mechanism. See discussion in #27360 for ELRS

note that this only impacts one board that I can see, the
BlitzF745AIO, due to the MCU vs DEFAULTGPIO interaction

Voltage Ratings

ThePeach FCC-K1 can be double-redundant on the power supply if two power sources are supplied. The two power rails are: POWER and USB.

:::note The output power rails FMU PWM OUT and I/O PWM OUT do not power the flight controller board (and are not powered by it). You must supply power to one of POWER or USB or the board will be unpowered. :::

Normal Operation Maximum Ratings

Under these conditions all power sources will be used in this order to power the system:

  1. POWER input (5V to 5.5V)
  2. USB input (4.75V to 5.25V)

Absolute Maximum Ratings

Under these conditions, all power sources cause permanent damage to the flight controller.

  1. POWER input (5.5V Over)
  2. USB input (5.5V Over)
