Another sensor which will be onboard the quadcopter is the voltage and current monitor from Attopilot. This device can measure up to 180A and will help to give accurate feedback about the state of the battery to the ground station while in flight. The currentĀ  is measured by a shunt resistor while the voltage is measured by voltage division. The two analog levels are the fed into the IMU board via two A/DĀ ports.
