# Digital Power Module (PM) Setup

{% hint style="danger" %}
Pixhawk 5X & 6X uses l2C digital protocol power sensing, so you will need to a digital power module. Digital power module will have a "D" at the end, such as PM02D. 
{% endhint %}

### PX4 Setup

{% hint style="info" %}
In master FW or 1.15 Stable, PX4 will auto detect the version below so you would not need to manually set this.
{% endhint %}

Low voltage (6S) Digital Power Module

* Enable Parameter `SENS_EN_INA226` (this is enabled by default)

High Voltage (12S/14S) Digital Power Module:

* Enable Parameter `SENS_EN_INA228` 

### Ardupilot Setup

{% hint style="info" %}
High voltage version (12/14S) are only support in Ardupilot 4.4 & later. These parameter below should be set by default. 
{% endhint %}

* `BATT_MONITOR` = 21
* `BATT_I2C_BUS` = 1
* `BATT_I2C_ADDR`
  * \= 0 Auto detect (Default in Ardupilot 4.4 & later)
  * \= 65 (For Low voltage (6S) Digital Power Module)
  * \= 69 (For High Voltage (12S/14S) Digital Power Module)

{% hint style="info" %}
In Ardupilot 4.4 and later, the BATT\_I2C\_ADDR for Pixhawk 6X is default to be 0. This will perform a auto detection of I2C address, therefore you do not need to change BATT\_I2C\_ADDR
{% endhint %}

### [PM02D](https://holybro.com/collections/power-modules-pdbs/products/pm02d-power-module)

This is the standard power module for Pixhawk 5X & 6X. It has XT60 pre-soldered and a low profile design, available in High Voltage (HV) and Low Voltage version (LV).

### PM08

This Power Module has two 5.2V power output port with independent circuits, BEC IC and circuitry that can provide redundant power to the flight controller.

* Support 2S - 14S Battery
* 200A Cont. Current Rating&#x20;
* Aluminum Case for Heat dissipation
