I recently purchased Robomaster EP Core, S1, and TT.

For EP Core, I was wondering where can I get additional parts like infrared distance sensor.  

The kit only comes with one.  The video shows it is possible to mount on all three sides.
I would like to know where I can get info on more compatible sensors mentioned like temperature, pressure ranging, and other sensors not included in the kit.
I didn't find those parts in the DJI store.


Thank you!
