We Build Devices That Ship — And Keep Working
A prototype that blinks an LED on the bench is a long way from a product that survives the field. EMC, thermal limits, power budgets, certification and ten-year supply chains are where embedded projects quietly stall — in the gap between “it works on my desk” and “it ships at volume.”
Most teams have strong firmware engineers or strong hardware engineers — but rarely one partner who owns silicon selection, schematic and PCB, firmware, RTOS, drivers, security and the test rigs that prove it all works together.
DevSpark closes that gap. We design, build and validate production-grade embedded hardware and firmware — from first schematic to certified, manufacturable product — to the reliability standards demanded by regulated and safety-critical environments.
End-to-End Embedded Engineering
From silicon selection to production hand-off — we cover every stage of your product’s journey.
Hardware & PCB Design
Schematic capture, multi-layer PCB layout, signal-integrity and power design — built around the right MCU or SoC for your cost, power and performance envelope.
Firmware & RTOS Development
Bare-metal and RTOS firmware (FreeRTOS, Zephyr), device drivers, bootloaders and OTA update mechanisms — robust, testable and field-upgradable.
Real-Time & Safety-Critical
Deterministic real-time control, motion and sensing systems, engineered to the discipline of regulated and safety-critical environments.
Connectivity & IoT
Wired and wireless connectivity — BLE, Wi-Fi, LoRa, CAN, Modbus, MQTT — with secure provisioning and edge-to-cloud data paths.
Security & Certification
Secure boot, encrypted storage and design for EMC, safety and regulatory approval — so certification isn’t an afterthought.
Production & Manufacturing Support
Design for manufacture and test, BOM and supplier optimisation, board bring-up, and production test rigs that catch defects before your customer does.
