IoT Development Services — End-to-End Connected Devices
Reading time: 2 minutes.
Connected Devices That Work in the Real World
IoT projects fail when hardware and software teams operate in silos. CimpleO delivers end-to-end IoT engineering — PCB design, embedded firmware, wireless communication, cloud backend, and mobile app — all from one team. The result is a system where every layer was designed to work together, tested together, and shipped together.
Hardware & PCB Design
Custom circuit board design from schematic to production-ready layout. We select components for your operating conditions — temperature range, power budget, form factor, and certification requirements — and design for manufacturability from the start. Prototypes to mass production runs, handled end to end.
Embedded Firmware
Firmware written in C and C++ for STM32, ESP32, AVR, and other embedded targets. We implement sensor drivers, communication stacks (BLE, LoRaWAN, MQTT, MODBUS), RTOS task management, and OTA update mechanisms. Power-optimised for battery-operated devices and hardened for industrial operating conditions.
Cloud Platform & API
Device data needs somewhere to go and something to do with it. We build the cloud backend that ingests telemetry from your devices, stores it efficiently, and exposes it through APIs to your dashboards and third-party systems. Built on AWS or Azure with device authentication, rate limiting, and horizontal scale.
Mobile & Dashboard Interfaces
The field app or web dashboard that makes your device data usable. Live sensor readings, device configuration, alert management, and historical trends — designed for the operators and engineers who actually work with the system every day. Available as web dashboard, iOS/Android app, or both.

Frequently Asked Questions
How much does IoT development cost?
A focused single-device firmware + cloud backend project typically runs $20,000–$60,000. Full end-to-end IoT solutions — PCB design, firmware, cloud platform, and mobile app — range from $60,000–$200,000+ depending on hardware complexity, connectivity stack, and production volume targets. We scope thoroughly before committing to a price.
Do you handle both hardware and software?
Yes. Our team covers the full stack: schematic review and PCB layout, embedded firmware (C/C++, FreeRTOS), wireless connectivity (BLE, LoRaWAN, NB-IoT, GSM), cloud backend (AWS IoT, Azure IoT Hub, ThingsBoard), and mobile or web dashboards. You get one team that understands the whole system, not a hand-off between hardware and software vendors.
Can you build a working prototype before full development?
Yes, and we recommend it. A 4–6 week proof-of-concept on evaluation hardware (ESP32, STM32 Nucleo) validates your architecture and key risks before you invest in custom PCB design. We'll tell you honestly if the prototype reveals problems with your concept.
How long does an IoT project take from start to production-ready?
Firmware + cloud for a single device type: 3–5 months. Full product including custom PCB, certification testing, and production firmware: 6–12 months. Hardware always sets the timeline — if boards are in fab, we start firmware on evaluation kits to avoid idle time.
Do you support post-launch — OTA updates, device management?
Yes. We implement OTA update mechanisms as part of the firmware, not as an afterthought. Post-launch we can provide a retainer for fleet monitoring, firmware updates, and cloud infrastructure management. Most production deployments have ongoing operational needs.
What industries have you built IoT for?
Logistics and asset tracking (2.2-year GPS tracker), agriculture (soil sensors, automated irrigation), industrial automation (CAN bus, Modbus, predictive maintenance), smart metering (LoRa multi-node networks), and healthcare-adjacent monitoring. See our IoT projects for specifics.
