Hardware Introduction

2018-11-06

This document introduces the hardware involved in the development of an application payload with Payload SDK.

Payload Weight Requirements

Flight platform Weight
M200 series Less than 600g

Payload SDK Development Kit

You can get the Payload SDK development kit after becoming a Payload SDK enterprise user. The Payload SDK development kit allows you to explore the Payload SDK features and facilitates quick development.

The Payload SDK development kit contains the following components:

  • DJI SKYPORT Adapter x1
  • Payload SDK Development Board x1
  • Round Ribbon Cable 250mm x1
  • Flat Ribbon Cable 30mm x1
  • Ribbon Cable Connector x3

DJI SKYPORT Adapter

Introduction

The SKYPORT adapter is docked to a M200 series' gimbal port to connect user payloads and UAVs. For the connection of the SkyPort and the payload, see SKYPORT installation.

Payload SDK Development Board

The Payload SDK development board helps you explore the Payload SDK features to quickly familiarize yourself with the Payload SDK usage and prototype your application during the preliminary R&D phase. You can port the Payload SDK to your own payload platform later. The Payload SDK development board uses the MCU STM32F407IGH6.

Hardware description

Interface Number Interface Name Interface Description
J5 SKYPORT connector Connect to the SKYPORT adapter using the Round Ribbon Cable 250mm.
J7 External Test Port Transfers the UART/CAN signal from the SKYPORT adapter into a pinned connector to facilitate connection to other platforms.
