Building the Arduino Receiver Electronics for Yellow Plane

Building the Arduino Receiver Electronics for Yellow Plane

Building the Arduino Receiver. The whole board and micro weighs in at 22 grams. The supply will be a 3C Lipolly

The Xbee need around 220mA and the Arduino draws 100 mA driving all 6 servo PWM signals, and not the motors. All up say 750mA in a 750mAh 3C

The Xbee Vin (max 16V) and Arduino VIN (max 20V) hare both powered from the supply battery 11.1 V directly as the both have internal regulators.  This helps isolate any noise from the Arduino and ore servos from being superimposed on the Xbee supply rail.

All six PWM outputs are connected to the servo pins, analogue inputs are also routed to pins. The Xbee’s RSSI signal is connected to D2 (pin 5) I have a separate BEC for the servos and all the 0V’s are tied together
