What we offerThree service lines that fit together.
Embedded & IoT engineering, PCB design & component assembly, and IT services — three equally core disciplines, not one flagship and two add-ons. Take one, or take all three as a single build.
Embedded & IoT Engineering
Firmware, sensors, and connected devices, engineered to work in the field rather than only on the bench. We take a device from proof-of-concept through to field-ready hardware, and connect it to the systems that make its data useful — motor-control systems, CAN-bus tools, and the dashboards that watch them.
Capabilities
- Firmware & embedded systems
- Motor-control systems
- CAN-bus tools & adapters
- Sensor integration
- Real-time device dashboards
- IoT connectivity & telemetry
Who it's for
- Manufacturers adding smart features to existing hardware
- Teams reverse-engineering or extending a third-party controller
- Businesses that need a connected device to report real data, reliably
PCB Design & Component Assembly
Circuit design, PCB layout, and component assembly from our unit in Madurai. One partner for schematic, board, and build — so you are not coordinating a designer, a fabricator, and an assembler separately. Built for agri-industry, EV, and industrial electronics, with designs anchored in what can actually be sourced nearby.
Capabilities
- Schematic capture
- PCB layout & design-for-manufacture
- Component sourcing guidance
- Component assembly
- Board bring-up & testing
- Small-to-mid volume builds
Who it's for
- Spare-parts manufacturers moving into EV components
- Agri-industry businesses needing custom control boards
- Teams that need a board built once and produced reliably
IT Services
Software that runs the business. We build web and mobile applications, IoT data platforms and dashboards, and domain solutions for the Fashion & Apparel industry — designed, deployed, and maintained. The same team that builds your hardware can build the platform that reports on it.
Capabilities
- Web & mobile applications
- IoT data platforms
- Dashboards & reporting
- Fashion & Apparel domain solutions
- Cloud deployment
- Maintenance & support
Who it's for
- Businesses that need a dashboard for hardware already in the field
- Fashion & Apparel companies digitising a workflow
- Teams that need software maintained after launch, not abandoned
Three ways to work with us.
Project-based
A defined scope with a clear deliverable — a board, a firmware build, or an application — priced and timelined upfront after discovery.
Retainer
Ongoing engineering or software support for a product already in the field, billed on a recurring basis as work comes up.
Consulting
Technical advisory for a business evaluating a move into EV components, IoT, or a new software platform, without committing to a full build yet.
What clients usually ask.
Can I hire TKAAR for just one part of a project, like PCB assembly?
Yes. Each service line — embedded & IoT, PCB design & assembly, and IT services — can be engaged on its own or combined into a single build.
What volumes can the PCB assembly unit handle?
We're set up for prototype through small-to-mid volume builds. Tell us your target volume and timeline and we'll confirm fit.
Do you sign NDAs and handle IP ownership?
Yes, we work under NDA on request and agree IP ownership terms with each client before design work begins.
How long does a typical engagement take?
It depends on scope — a firmware update can take weeks, while a new board plus application can take a few months. We give a specific estimate after the discovery step.
Not sure which you need?
Tell us the product you are trying to ship. We will tell you what it takes across hardware and software — and where we can shorten the path.
