  • There is no current sensing on VCC out of the powerpath switcher, which means that when we are powering the rocket off of the battery we have no idea what the current draw on the 12V line from the CAN bus is.
  • There is significant interference between the 24->13V regulator (likely the inductor?) and its current sensing voltage. The current sense voltage at idle is about 12 mV and we're seeing 500 mV spikes on the pin highly regularly at 8.2 kHz.
