Embedded Systems · PCB · Firmware
Schematics, PCB layout, firmware and an enclosure you can hand to a customer, plus the app and cloud that make the device useful. One team, one schedule.
In Short
It runs from requirements to circuit design, PCB layout, component sourcing, firmware, enclosure, testing and preparing for small-batch manufacturing. Most delays come from handoffs between separate electronics, firmware and app vendors. Unlike most embedded systems companies in Bangalore, LitSpark keeps all three under one plan, so the board, the code and the app are tested together.

What We Do
Power, size, sensors, connectivity and cost targets checked before a single trace is drawn.
Multi-layer layouts with design-for-manufacture checks and a costed bill of materials.
Drivers, power management, OTA updates and secure boot on the microcontroller you choose.
Boards fabricated, assembled and debugged until every function works on the bench.
3D-printed and then production-ready enclosures that fit the board and the user's hand.
Bluetooth or Wi-Fi app and dashboard so the device is useful from day one.
Product Types
Wearables, smart home devices and accessories with a companion app.
Sensor nodes for temperature, vibration or energy on the factory floor.
Non-invasive monitoring devices built with documentation for certification.
Add connectivity to machines, meters or vehicles you already own.
How It Works
Dev boards and breadboards prove the core function cheaply.
Custom PCB and firmware that matches the real size and power budget.
Bench, field and battery tests, then a second board revision.
Manufacturing files, test jigs and help choosing an EMS partner.

Pricing
Engineering cost depends on board complexity and how many revisions the product needs. Components and fabrication are billed at cost. Projects start at ₹50,000, with a fixed quote after a short call.
| Package | Budget | Timeline |
|---|---|---|
| Proof of ConceptDev-board build to prove the idea. | Starting at ₹50,000 | 3–5 weeks |
| Engineering PrototypeCustom PCB, firmware, enclosure, app. | ₹1.5–2.5 lakh | 6–8 weeks |
| Pilot-Ready ProductRevisions, DFM, test jigs, certification prep. | ₹3.5 lakh+ | 1–2 months |

Read ArticleA proof of concept takes three to five weeks. An engineering prototype with a custom PCB, firmware and enclosure usually takes six to eight weeks.
Yes. Electronic product design covers the circuit, PCB and enclosure, and embedded systems covers the firmware running on it. We do both, plus the app and cloud, as one hardware project.
We prepare manufacturing files, test jigs and documentation, and help you choose and brief an electronics manufacturing partner for the pilot batch.
Yes, and that's our edge. The same team writes the firmware, the Bluetooth or Wi-Fi app and the cloud dashboard, so they're tested together.
Rates vary with seniority and scope, but the bigger cost driver is board revisions. Picking a team that designs firmware and the app alongside the PCB avoids re-spins caused by late changes. The city's PCB fabs and suppliers also keep revision cycles short.
You do. Schematics, PCB files, BOM and firmware source code are handed over at every milestone.
