System architecture
We design the bones — block diagrams, interface contracts, and component selection — so the rest of the build sits on solid ground.
Embedded systems consultancy
We design electronics, firmware, and software for connected products.
Bitmask helps companies bring connected hardware to market — from system architecture and rapid prototyping through to production-ready firmware and automated test rigs.
What we do
Full-stack engineering for connected products
From silicon to cloud — the same team that designs your PCB writes the firmware that runs on it and the software that talks to it.
Firmware development
Production firmware on Zephyr, nRF Connect SDK, and bare-metal — sensor pipelines, BLE/Wi-Fi/LTE-M stacks, OTA, and power-aware scheduling.
Schematic & PCB design
From breadboard to manufacturable PCB in KiCad — RF layout, EMC-aware routing, DFM, and BOM strategies for resilient supply.
Software & cloud
Companion mobile, desktop, and web apps; cloud back-ends and dashboards that turn device data into something a customer can use.
Rapid prototyping
Off-the-shelf modules and 3D-printed enclosures to validate a product idea quickly — investor-ready demos in weeks, not quarters.
Automated test rigs
Production-line and lab test fixtures with custom firmware, instrumentation, and reports — so every unit ships proven, not assumed.
