Power Module

Overview

• It is best to power your BH with a power module to reduce the chances of a brownout.

• This page explains how to set up Power module to measure battery voltage and current consumption.

• BH has two power sources, all of them can be used simultaneously as they are protected by ideal diodes.

  <1> Connect 5V 1A power adapter to the Raspberry Pi’s microUSB port. Raspberry Pi will provide power to the BH.

  <2> Use BECs that provide voltage in a range of 4.8-5.3V.

Connecting the PM to BH

Power Module Configuration in Mission Planner

• A power module can be used to provide a stable power supply to the system, and to accurately measure the battery voltage/current in order to trigger a return to launch on low battery. The bellow explains how to set up and configure power modules using Mission Planner.

• Mission Planner Setup

  Battery measurement is primarily set up in the Mission Planner‘s INITIAL SETUP

  Optional Hardware

  Battery Monitor screen.

• Enable Low Battery Alert
