# Holybro PM02D Power Module

The Holybro PM02D digital power module provides regulated power to flight controller and power distribution board, and sends information to the autopilot about battery voltage and current supplied to the flight controller and the motors.
There are two versions: high voltage (12S/14S) and low voltage (6S).

The power module is connected using the I2C protocol.
It is designed for flight controllers based on the Pixhawk FMUv5X and FMUv6X open standard, including the [Pixhawk 5X](../flight_controller/pixhawk5x.md).

::: info
The PM is **NOT** compatible with flight controllers that require an analog power module, including: [Pixhawk 4](../flight_controller/pixhawk4.md), [Durandal](../flight_controller/durandal.md), [Pix32 v5](../flight_controller/holybro_pix32_v5.md), etc.

## PX4 Configuration

Low voltage (6S) Digital Power Module
- Enable parameter [SENS_EN_INA226](../advanced_config/parameter_reference.md#SENS_EN_INA226)

High Voltage (12S/14S) Digital Power Module:
- Enable parameter [SENS_EN_INA228](../advanced_config/parameter_reference.md#SENS_EN_INA228)

Note that the current divider and voltage divider should not be set in the [Battery Configuration](../config/battery.md) (the default values are accurate within 5%).
