The Holybro PM02D power module provides precise current and voltage sensing for your flight controller. This digital module efficiently converts battery power into a stable 5.2V output for critical electronics while accurately monitoring power consumption.
The listing calls it essential for safe, reliable drone operation and for analysing flight time, and a key component for modern UAV builds.
The voltage and current monitor has an I2C-compatible interface, which means the readings arrive as digital data instead of analogue voltages.
Digital current and voltage sensing: precise measurement.
Stable 5.2V regulated output: up to 3A.
Real-time battery monitoring: tracks consumption in flight.
I2C-compatible interface: digital readings for modern flight controllers.
Compact and lightweight: 20g.
Wide input range: 2S to 12S.
A digital power module measures battery voltage and current with an onboard sensor and sends the values to the flight controller over a digital bus such as I2C. Unlike an analogue module, the readings are not affected by ground noise or by the scaling of an analogue-to-digital converter, so they are usually more accurate and need less calibration.
The onboard regulator also provides a clean 5.2V supply for the flight controller. Check that your flight controller and firmware support the I2C power monitor and select the correct battery monitor type in the parameters.
Do not use the regulator to power servos or other high-current devices unless the manual says it can, because a heavy load can pull the supply down and reset the flight controller. Keep the module cool and make sure that the solder joints and connectors are secure, because this part carries the full current of the aircraft.
