Intelligent power monitor and fuel gauge.
- Supports 2-6S batteries (6-26V) and currents of up to 100A when actively cooled.
- CANbus interface using DroneCAN (UAVCAN v0) protocol.
- Compatible with PX4 and Ardupilot
- Bright RGB LED indicates battery state of charge and device status.
- Multiple modules on the same bus can monitor multiple power sources.
- Open Source firmware.
Note: Unlike the Power Module this device requires independent 5V power.

The smaller the shunt resistor value the lower the heat dissipation requirements which increases the maximum current limit. However shunt resistor value is inversely proportional to current-measuring resolution so a `High Current` variant has 10 times less current-measuring resolution than the `Low Current` variant. For reference the theoretical resolution for the `High Current` variant is 50mA and for the `Low Current` variant it is 5mA.
