We are an Indore-based engineering team. For Pune companies we design the electronics, write the firmware and build the companion apps for connected hardware products, including vehicle-mounted equipment.
Our Pune client Vaara makes refrigerators that are installed in vehicles. They needed a controller board and the software that runs it. Inurum designed the controller electronics (PCB) and wrote the firmware. The mechanical design, the refrigerator itself and the vehicle installation were done by the client. This split is how most of our hardware work runs: the client owns the product and its mechanics, and we deliver the electronics and firmware that make it work.
A controller inside a vehicle has to run from a vehicle power supply and cope with vibration, heat and electrical noise, so these are the points we design for from the first schematic. Because we work remotely from Indore with regular calls and shipped prototype boards, distance to Pune has not been a limit for this project.
ARM Cortex-M, ESP32, RISC-V. Bare-metal C/C++, FreeRTOS, Zephyr. Multi-layer PCB layout with signal integrity review.
BLE, Zigbee, LoRaWAN, NB-IoT, LTE-M, MQTT/AMQP. Full protocol stack from sensor to cloud gateway.
Cross-platform iOS & Android apps with BLE device pairing, real-time telemetry dashboards, and OTA triggers.
Node.js/Go backends, AWS/Azure device provisioning, secure OTA update infrastructure with staged rollouts.
HSM integration, AES-256 encrypted storage, certificate pinning, and secure boot for production deployments.
DFM review, testing jigs, fleet provisioning scripts, and ongoing firmware release management post-launch.
Pune has many hardware companies with a strong mechanical side that need an electronics and firmware partner. We work well with:
Another vehicle-mounted electronics project: we designed the controller PCB and firmware for a remote-start and telematics system for heavy-duty commercial trucks, built for an international client under NDA.
View Case Study →Our own product: a 4G vehicle tracker with live location, route playback and an engine cut-off relay.
View Product →The two services behind the refrigerator controller, available separately or together.
Firmware → PCB design →No. Our team is based in Indore, Madhya Pradesh. We work with Pune clients remotely and ship prototype boards to you.
The controller electronics (PCB) and firmware for in-vehicle refrigerators made by Vaara. The mechanical design and the refrigerator itself were the client's work.
Yes. That is the most common setup: you bring the mechanical product, we design the board and write the firmware to fit it.
It depends on board complexity, connectivity and testing needs. We give a roadmap after a free technical discovery call.
Yes, firmware maintenance and over-the-air (OTA) update support can be agreed as part of the project.
