I was wondering how much internal memory the Robomaster had (and the CPu it used) so I could have an idea of how complex programs for it could be. It turns out that barring some artificial limitation, they can be pretty complex.

Here are the likely CPU specs:

ARMv7-A
Cortex A7
4 cores
1.5 GHz (not 1.2)
Integrated Mali T628 MP2 @ 600 MHz


And, with a smaller confidence, the memory specs:

4 Gb LPDDR3 (main memory)
4 Gb eMMC (internal storage)

In other words, if DJI allows us by improving and expanding the available APIs, we would be able to do some pretty neat things with it.

Here are a couple photos showing the memory chip.
Here's a closeup of the chip.

The above chip can be seen in the lower right of the photo below.


For those who may be unaware, I posted photos of the Intelligent Controller's PCB on my Hackaday IO project page.

Thanks to BGA, we have a pretty good idea about the processor but the memory chip is still a bit of a mystery.

Hello @DJI  Stephen. Can DJI confirm the type and amount of memory installed in the RoboMaster S1 Intelligent Controller?
