• Avoiding damage to the device due to improper operation, please refer to the User's Manual before connecting the onboard computer or a third party onboard computer to DJI's drones.
• The interface in the illustration of this document is the interface of the drones. TheNOTEof the interface in the onboard computer, please refer to Manifold 2 User's Manual, for the interface of the third-party onboard computer, please refer to the manual of the purchased.
• Some hardware interfaces that were not described in this document are temporarily unavailable.

Figure 1 display the method of device connection.

Using M210 V2 Series

M210 V2 series include M210 V2 and M210 RTK V2. For details, please refer to User's Manual.

NOTE

• The pin identification shown in the figure is the tail of the drone from top to bottom. The details for the onboard computer or third-party hardware platform, please refer to the User's Manual of the purchased.
• If the onboard computer (such as Manifold 2) and the third-party onboard computer triggers the power-off protection mechanism (power-off) of the M210 V2 series due to the higher current (peak current reaches 24V/5A) Or restart frequently), please disconnect the power output interface (XT30), check and adjust the current connection of the onboard computer and the third-party onboard computer, and then reconnect the power output interface.
• It is recommended to use Onboard Computer Mounting Bracket to make the safety and reliability of the onboard computer.

Connected To Manifold 2

When connecting the onboard computer Manifold 2 to the M210 V2 series, please use the USB to TTL cable (FT232BL) and the double-headed USB cable as shows in Figure 2.

• Use USB cable
  Manifold 2 communicates with the drone through dual-head USB cable.
• Use the serial cable
  • Method 1: Use the serial cable in Manifold 2 to connect the expansion interface at the rear of the drone and the UART1 interface in Manifold 2 (the device number in Manifold 2 is ttyTHS2);
  • Method 2: Use a USB-to-serial cable to connect the expansion interface at the rear of the aircraft to the USB interface of Manifold 2 (the device number in Manifold 2 is ttyUSBn, n is 0, 1, 2, ...).
• Power Output
  • In order to avoid interference with the normal operation of the drone, please ensure that the voltage of the onboard computer is between 18V and 26V, and the current is constant at 2A;
  • Set the power interface on or off in utility/bin/ (reset the power switch after the drone restarts); ./M210ConfigTool --usb-port/dev/ttyACM0 --config-file UserConfig.txt --power-supply on

NOTE

• The voltage of M210 V2 Series is 3.3V;
• If developer want to use Matrice 210 RTK for Time Synchronization, please use the cable connect the interface SYNC Line on Manifold 2 to the PPS and GND pins on the rear of the drone.

Connected To Third-Party Onboard Computer

According to the situation of the third-party onboard computer, connect the M210 V2 series to the third-party onboard computer:

• Use the USB cable
  Communicate with the drone through the dual USB cable.
• Use the serial cable
  • Method 1: Connect the expansion interface at the tail of the drone to the UART1 interface of the third-party onboard computer using a serial cable;
  • Method 2: Use a USB-to-serial cable to connect the expansion interface at the rear of the aircraft to the USB interface of a third-party onboard computer.
• Power Output
  When using an external power supply to power a third-party onboard computer, please ensure that it does not interfere with the normal operation of the drone.

NOTE

• Please use USB cable and serial port cable connect the third-party development platform to M210 V2 series at same time;
• Don't use the VCC pin to power the third-party onboard computer, otherwise the drone or the third-party onboard computer may be damaged.

Using M300 RTK

NOTE

• The voltage of the serial port on the M300 RTK and OSDK adapter board is 3.3V;
• When installing Manifold 2 or a third-party onboard computer on the Matrice 300 RTK, please use the OSDK adapter board;
• When using a third-party platform as an onboard computer, please avoid generating magnetic fields.

In order to facilitate developers to fix the onboard computer Manifold 2 or a third-party onboard computer on the M300 RTK, DJI provides an onboard computer adapter board, which provides the XT30 24V power port, OSDK serial port and OSDK USB 2.0 port, developers can design the onboard computer adapter board according to the structure and interface of the adapter board. To avoid accidents such as burning the adapter board or onboard computer, please read the following carefully.

Adapter Board Interface

NOTE The details for installing the onboard computer adapter board on the M300 RTK, please refer to the Onboard Computer Adapter Board User's Manual.
