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.


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)
