Fast testing. Fast decisions. Lower risk.
We build prototypes in the United States. That means fast test cycles, clear communication and quick fixes when something doesn't behave. Every design is proven before it moves to EMSG for production.
Quick-turn PCB assembly
Prototype boards built quickly so design questions get answered with hardware, not opinions.
Full product-level prototypes
Electronics, enclosure and firmware together, so fit and function are confirmed before tooling.
Functional testing
Bring-up, validation against requirements and test procedures that carry into production.
EMI & EMC pre-testing
Pre-compliance scans that find emissions problems before a formal certification lab does.
Thermal & stress testing
Full-load thermal characterization, environmental and stress testing for products that run continuously.
Where we've applied this.
Formaldehyde Monitor
A low-cost, connected air quality monitor built around a sensitive formaldehyde sensor and an ESP32.
US-Made Modular Bitcoin Miner
The first US-made, scale-modular bitcoin miner, built on our patented power and networking technology.
