Component development
Drone electronics designed to your platform's requirements.
For anything not covered here, send the brief and an engineer will reply.
Are Nexospark products designed and manufactured in India?
Yes. Every module is designed, laid out and assembled by our engineers in Kottayam, Kerala. Nexospark is recognised under Make in India and supported by Kerala Startup Mission.
Can you integrate your subsystems into our airframe?
Yes. We integrate our control links, speed controllers, sensors and networking into OEM and programme airframes, and adapt boards to partner requirements.
Do you work on defence programmes?
Yes. We hold a Letter of Interest and a Letter of Recommendation from the Indian Army, and have trained Army personnel in drone assembly, flight operations, maintenance and field deployment.
Which protocols do your components support?
It depends on the module. FalconLink runs ExpressLRS on 2.4 GHz; the CAN / I²C splitter and the air speed sensor work on standard flight-controller buses; the Ethernet switch links flight controllers, cameras and payloads. Ask for the datasheet of the module you need.
Can you train our crews?
Yes. We have trained more than 100 students and Indian Army personnel in assembly, flight operations and field maintenance.
How quickly do you respond?
An engineer replies to every enquiry within 24–48 business hours.
Do you take international partnerships?
Yes. We look for technology integration partners in US, EU and Asian markets for joint-venture engineering projects.
