You can power Luci through the PWM OUTPUT pins or with the POWER connector on the bottom.

When powering via PWM OUTPUT connect your power source to the + and - pins on any of the 6 headers. This power source is typically a BEC on a drone's power distribution board or ESCs.

Voltage Requirements

Luci can accept a wide supply voltage range, from as little as 4.5V up to 5.5V.

It is important to note that the voltage supplied to the system through the POWER or PWM OUTPUT headers is the same voltage supplied to USB devices connected via the Edison's OTG port. If you intend to use external USB devices in this manner, it is suggested the power supply provide a voltage between 4.75V and 5.25V to properly follow the USB 2.0 power standard.

It is imperative that when supplying power to Luci through the PWM OUTPUT headers that the connector's polarity is correct. Improperly inserting the connector could irreversibly damage Luci.

The POWER connector on the bottom of Luci follows the Dronecode ANALOG POWER standard.

The CURRENT signal should carry an analog voltage from 0-3.3V for 0-60A as default. For high-power units the range should be 0-3.3V for 0-120A. The VOLTAGE signal should carry an analog voltage from 0-3.3V for 0-50A as default.

The VCC lines have to offer at least 2.5A continuous and should default to 5.3V. A lower voltage of 5V is still acceptable, but discouraged.
