The Hidden Semiconductor Dependency of Indian UAVs
- Indian drone flight controllers are increasingly Indian-designed at board level.
- The chips inside them - MCUs, IMUs, GNSS, MOSFETs, BMS ICs - still arrive largely through distributors of foreign brands.
- The dependency has moved down a layer, from the board to the silicon.
- Distributor drone portfolios are a practical window onto the imported bill of materials.

The development
At Drone Expo 2026 in New Delhi, several Indian companies - Arkin Labs, YARI Robotics and Zerosum Technologies among them - marketed complete flight-controller, GNSS and power-module stacks, with Arkin and YARI stating their products are designed and built in India. On the same floor, component distributor Millennium Semiconductors exhibited with a published drone portfolio spanning processors, CMOS image sensors, GPS and cellular modules, motor-control chips, MOSFETs, Hall sensors, battery-management ICs, power components and connectors - supplied from globally sourced component brands.
What the evidence shows
- Indian flight-controller vendors describe Indian design and manufacture, but none publishes which microcontrollers, IMUs or GNSS chipsets their boards use.
- Distributors now market drone-specific portfolios of foreign-brand semiconductors to Indian UAV makers.
- Techadyant's UAS sovereignty assessment already rates microcontrollers, IMUs, power-management ICs and power electronics among the most import-exposed layers of Indian drones (an internal, indicative estimate).
Why it matters
- 'Designed in India' at board level and 'dependent on imports' at chip level are both true - the dependency has moved down a layer, not away.
- Distributor line cards are a cheap, repeatable way to read the imported bill of materials behind Indian drones.
- Any sovereignty claim about Indian drone avionics should be tested at the chip, not the board.
What we cannot yet say
- Which specific brands dominate Indian drone electronics - the distributor line cards have not yet been captured in detail.
- The semiconductor bill of materials of any named Indian flight controller.
