Embedded Firmware Development for Hardware Companies

You have a hardware design. You need firmware that actually ships — on time, with clean code, and without months of onboarding a full-time engineer.

CimpleO builds embedded firmware for IoT devices, industrial systems, and custom hardware. We’ve shipped real products: a 2.2-year-battery asset tracker (STM32 + GSM), a UHF RFID module (JRD-100), a LoRa-based smart metering network, and a portable ISP programmer for AVR and ESP32.

What We Build

IoT & Asset Tracking Firmware for GPS/GSM trackers, LoRa sensors, BLE beacons. Low-power design, OTA update support, reliable transmission in bad connectivity. Our IoT GAT tracker runs 2.2 years on a single charge.

Industrial & Automation CAN bus, Modbus, RS-485 stacks. RTOS scheduling for time-critical processes. MISRA C where compliance matters.

Custom Modules & Hardware Products From bare-metal BSP bring-up to full application firmware. We built the JRD-100 UHF RFID module and A9G GPS/GSM development board firmware from scratch.

Smart Metering & LoRa Networks Multi-node LoRa networks with cloud dashboards. Automated meter reading for electricity, water, gas, and heating — see our IoT Home Smart Cloud project.

How Engagement Works

We work as a contract firmware team — no recruiter fees, no 3-month ramp-up. Typical engagements:

Fixed-scope firmware project: defined deliverables, agreed timeline
Dedicated embedded engineer: monthly retainer, embedded in your process
Code audit & rescue: existing firmware with reliability or power issues

Most projects start with a 1-week technical scoping call. We review your schematics, hardware constraints, and timeline — then give you a concrete proposal.
