Hi there, im a Dji Technician,
Both cameras
mini 1 / se / 2 are the same, dji only changes de lens that has de 4k/silver label, but the hardware its the same.
the things occurs on the mainboard, that are not the same and has diferent capabilities for decoding image, here is where 4K appears Haha!
you can upgrade your
mini 1 installing a
mini2 mainboard, and use it as is.
but you will have to Recode the gimbal with python software, if don't do this, the gimbal does not calibrate.
also a message of "Gimbal Imu Error" will appear forever, works great but the error when you start your drone will stay forever.!
hope this helps u !
