Arduino uav telemetry and power distribution system

This system was designed to gather telemetry from onboard the drone and send it to a laptop base station. The system gathers data on internal and external temperature and humidity, and altitude. It also monitors the temperature of the speed controllers and both the high-current LiPo (brushless motor) battery and low-current Li-Ion (telemetry and controller receiver) battery.

An additional board provides power distribution for all the systems besides the high-current brushless motor power. It contains 12V rails for the FPV camera system and 5V rails for the control surface servos and telemetry board.
