When off-the-shelf doesn’t fit, we design from scratch

We’ve been building custom electronics and embedded firmware since 2014. We have transformed some of those one-off designs into products that are now available worldwide. We work through the full cycle of schematic, PCB, firmware, mechanical, compliance, and production.
How a project typically runs
01
Concept & requirements
We work through your brief, flag constraints, and agree on what “done” looks like.
02
Schematic & PCB layout
Circuit design, component selection, and board layout. Designed for manufacture from the start.
03
Firmware & prototype
Embedded firmware, prototype assembly, functional testing with our in-house equipment.
04
Compliance & production
Pre-compliance EMI testing, mechanical integration, and a pathway to volume production if needed.
Scope of work
- Electronic product design and prototyping
- Schematic design
- Prototype assembly (UK based)
