Hi,
on the top of the M300 we have USB type C for OSDK connection.
According to the documentation under https://developer.dji.com/onboard-sdk/documentation/quickstart/device-connection.html

"DJI provides an onboard computer adapter board, which provides the XT30 24V power port, OSDK serial port and OSDK USB 2.0 port"

Where can I find this onboard computer adapter board? I didn't see anything about it on dji sales site.

I've been wondering the same thing. The only reply I got was to make a custom cable with the USB-C connector.

Hey did you figure out how to interface the onboard computer with the 300 RTK ? I am having the same issue and not sure how to custom make my own cable for it. (I am using Jetson TX2 for onboard compute)

Just buy simple adapter from type c to 24 pins, and follow the instructions under :
https://developer.dji.com/onboar ... ice-connection.html

example for adapter :

It worked for me perfectly.

Thanks for the reply and it is very helpful. Also can I just use the USB wires from the usb-c pins to enable the drone to device communication (running ROS osdk) or do I have to use the UART rx/tx for it ? (I am new to this and want to confirm so that I don't damage any hardware)

Do you have a more detailed model number of what you ordered. I know some boards dont ship with resistors to make the usb c work and such.

What if all I want to do is connect an XT30 adapter for 24V power?

Look at the describtion on offical website.

Where can I find a waterproof ODSK connection?

Hi, sorry this does not answer your question. I am wondering is there any onboard computer for DJI that uses RTOS?

I saw an OSDK Payload manufacturer using the same solution as well, it is a M300 Sniffer. could check with them.https://purway-innovate.com/uavgasdetector
