As an interesting side note...

Has some pretty decent internal shots of the "Lightbridge 2" discreet Lightbridge module.
And for once, the important chips (mostly) aren't covered with a bunch of black gunk.
Of note are:
- 1x DM385AAAR01 aka TI "DaVinci" DSP
- 2x MT41K128M16JT-125 IT:K aka Micron DDR3 SDRAM 2 Gb (256 MB) RAM
- 1x MT29F1G16ABBEAH4:E aka Micron 1Gb (128 MB) SLC NAND
- 1x ADV7610 aka Analog Devices Low Power, 165 MHz HDMI Receiver
- 1x AD9363BBCZ aka Analog Devices RF Agile Transceiver w/ FDD/TDD 2x2 (unable to find exact datasheet)
- 1x LPC1549J aka NXP 32-bit ARM Cortex-M3 microcontroller (unable to find exact datasheet)
- 1x ALTERA Cyclone V FPGA (unable to read model number)
There are a few other ancillary chips, probably RF related, but I believe the above chips are the "heart" of the Lightbridge2 setup.
Obviously the Cyclone is the "brains" of the operation, in concert with the TI DSP.
As the Cyclone is a FPGA, also means DJI can tweak quite a bit with only software updates.
I know the P3 also has the Cyclone at the core of it's "Lightbridge", and apparently the P3P has the DaVinci as well.
Infer what you will...
