Specifications

Electrical

Rating	Value
Input voltage	15 to 57 V
Continuous current	100 A
Burst current	150 A for 10 s

Outputs

Output	Voltage	Current
Autopilot power	5.3 V	2.5 A
Companion computer	9 V or 12 V, set by a switch	2.5 A

The 12 V setting needs a 6S or larger battery.

Current and voltage monitor

Part	Specification
Monitor	TI INA228 : 20-bit, I2C address 0x45
Shunt	0.3 mΩ, between V_IN and V_OUT
Current range	136 A on the ±40.96 mV input range, 546 A on the ±163.84 mV input range

The monitor measures the battery voltage at V_IN and the current through the shunt. The ±40.96 mV input range resolves smaller currents. Battery monitoring selects the range in PX4.
