SZ DJI Expertise Co., Ltd often known as at this time DJI is a significant electronics producer primarily based in China as its largely credited with creating the buyer drone trade. Whereas primarily identified for making drones they’ve expanded their portfolio into many different industries such Digital camera Gimbals, Transportable/Motion Cameras,, Wi-fi Microphones and now Transportable Energy Stations.
Whereas DJI’s core enterprise stays drones they’ve diversified over the past 5 years into extra of a way of life electronics firm and is continuous that development.
With the priority within the US different nations round knowledge safety and the risk China poses with the used DJI drones round important infrastructure DJI is dealing with a attainable ban within the US.
Within the huge quantity of hypothesis round this there has additionally been questions raised asking if DJI can survive with out entry to western parts.
In the present day I’m going to attempt to reply that.
DJI Now Vs Then
Traditionally DJI merchandise had been largely constituted of commodity off the shelf parts most made in or IP owned by western corporations, these consisted of the next
- Arm primarily based microcontrollers from ST Microelectronics – Flight Management.
- Gyro & MEMS From invenSense (TDK) – Flight Management
- Positioning Chipsets From UBlox – GPS.
- Leadcore Arm chipsets & DSP – Common Processing and RF.
- Video Picture processors from Ambarella – DVR
- FPGA from Lattice – Picture Processing & RF Heavy Lifting
- Wi-fi chipsets from DaVinci and Artosyn – Lightbridge and Ocusync hyperlink.
- Movidius/Intel – Object Sensing & VPS.
- Energy Administration From Texas Devices – Battery BMS and SMC.
- Sram/Rom/EMMC from Elpida,MXIC, Micron,Samsung
Nonetheless issues have modified lots within the final 5 years and DJI’s reliance on western parts has diminished dramatically.
Subsequent are some examples of DJI Drones and element provide adjustments over the previous 7 years.
DJI Drones unto the DJI Phantom 4 largely had similar remark choiceand utilization, whereas there was some various of element choice with early Lightbridge the remainder was largely the identical.
Right here you will notice DJI use a good mixture of western parts of their drones.
DJI Mavic Professional & Ocusync
The discharge of the DJI Mavic Professional was a giant shift for DJI, whereas the drone was largely a extra compact Phantom DJI Launched Ocusync, their new wi-fi video system, this was primarily based initially on off the shelf Leadcore chipset.
The Mavic Professional was the beginning of DJI beginning to peruse extra residence grown options with some parts being marked DJI as properly.
DJIs battery programs did nonetheless depend on administration programs by Texas Devices.
In 2019 DJI began to actually transfer away from off the shelf commodity elements for core parts and programs akin to flight management, picture processing and wi-fi video and moved to using customized ASICs into their merchandise.
Their newest wi-fi system Ocusync and video picture processing is now primarily based on what we consider is their very own in home customized Asics, this primarily based on Arm Cortex MCU and Ceva DSP IP and could be very related in design to chipsets by Leadcore and later Artosyn.
I’ve an in depth write up on the historical past of Digital FPV and particularly DJI Ocusync and its chipset beneath.
Historical past Of Digital FPV
DJI Ocusync Historical past
For the fundamental microcontrollers they’ve largely stopped utilizing ST Micro and the place wanted use the likes of GigaDevice and the DJI Air 2s is a superb instance of the transfer away from western elements for core parts in comparison with the previous.
DJI closely reuses their circuit designs and chipsets of their drones and different merchandise, for example DJI Ocusync 2,Ocusync 3 primarily based product makes use of both their P1 “Pigeon” chipset or its smaller brother the S1. Newer merchandise with O4 now use their newest S2 variant and this chipset is one among DJI’s core applied sciences and is deemed because the “Crown Jewels”.
You’ll solely discover these chipsets in DJI designed merchandise and makes them very identifiable.
The DJI Air 2 is a superb instance of the shift in comparison with earlier fashions, whereas western parts are nonetheless used the rely has dropped dramatically.
DJI Part Reliance In the present day
The DJI Mavic 3 and DJI Avata 2 are a few of DJI newest drones they usually highlights simply how far they’ve moved away from reliance on the west for key parts of their drones
The Mavic 3 is filled with customized ASIC’s such because the H6,E29, P1 Ect.
The brand new Avata 2 is a incredible instance of DJI’s ongoing discount in element rely and consolidation of programs operating on their customized silicon.
Of their cameras and imaging payloads DJI use both Sony picture sensors from Japan or Omnivision Picture Sensors from China’s.
In enterprise merchandise as a consequence of export restriction on FLIR thermal sensors DJI transitioned to a china primarily based equal some years in the past once more dropping extra western reliance.
Abstract
Whereas that is solely a small snapshot of DJI merchandise the truth is at this time DJI shouldn’t be closely reliant on western element provide to have the ability to manufacture their merchandise.
There are nonetheless some key western know-how that DJI does nonetheless use akin to MEMS from Invensense , GPS chipset from Ublox and advance energy administration parts from Texas Devices.
Nonetheless controlling provide of those within the world element market can be near not possible and DJI’s continued use of those parts is as a lot as a consequence of them being “best in class” than a pure reliance.
China primarily based options do exist.
In the long run DJI’s reliance on the west comes from gross sales greater than the rest and DJI proceed to be on the sharp fringe of drone know-how with the remainder of the harm being no less than 3 years behind.
