3DR Iris Plus Quadcopter Electronic Speed Controller (ESC) and Power Distribution Board (PDB) Replacement

はじめに

This guide walks you through the steps of removing the Electronic Speed Controller (ESC) and Power Distribution Board (PDB) of the 3DR Iris Plus. This part is what communicates commands from the flight controller to the motors, and distributes power to the rest of the drone. As stated in the Troubleshooting Guide, if the drone is powered, but it is not responding, it is possible the ESC/PDB is damaged. This guide requires the use of a soldering iron and a set of screw drivers.
