Power Board:

  • Vbat control (unlabeled between 12v and 6v) must be wired to pin 1 of its optorelay (immediately below the left main power connector)
  • Radio power control must be manually wired to a 2-pin KK connector (along with 5V) in the proto area
  • Optorelay for 6v control must be double up, and its associated resistor (vertical and to the left) halved to ~300 ohms

Arduino Shield:

  • Radio power control and VBat control must be manually wired (see tables above)
  • 12v control line transistor can be bypassed
  • motor driver is wired to serial uart 2
  • gumstix is wired to serial uart 1
  • tmp102 temp sensor resides on i2c bus
  • sbus wired to uart3
  • wiznet wired to default uart (shared with usb)
