What we do

## Your product’s electronics and firmware, from one team

We start from your requirements, even if they are not written yet, and deliver a board and firmware that are tested and ready for production.

### PCB design

Production-ready boards, designed from the first schematic to pass EMC testing and production test. Up to 12 layers, HDI and rigid-flex.

### Firmware development

The firmware that brings your board to life and keeps it up to date in the field: drivers, RTOS, industrial and wireless buses, secure boot and OTA.

How we work

## A date you can plan around

1.  Within 24 hours
    
    ### Technical answer
    
    An engineer replies, not a salesperson. NDA if needed.
    
2.  Within 48 hours
    
    ### Proposal
    
    For the feasibility study or, if the specification is ready, straight for the project.
    
3.  In 72 hours
    
    ### Feasibility study
    
    Architecture, risks, key parts, costs and timing become the specification. For complex projects, the duration is written in the proposal.
    
4.  From the order
    
    ### Design
    
    Hardware and firmware move forward in parallel, with deadlines written in the order.
    
5.  On the agreed date
    
    ### Tested prototypes
    
    Boards powered, measured and tested, with a report.
    

### Weekly status updates

You always know where we are.

### Our own design tools

BOM and availability checks, reviews, automated tests.

### ISO 9001 quality

Design reviews and complete documentation.

Case studies

## Real projects, real numbers

23 tests in ~75 s

Systems for harsh environments

### A rugged interface that updates in the field and never bricks

A portable, battery-powered unit that powers and controls two remote devices over isolated channels. The hard part was making it reliable far from any lab. Its firmware updates in the field and, if something goes wrong, rolls back on its own to the last working version.

Test systems for high-reliability applications

### Ten seconds to know whether a MEMS accelerometer really works

A bench and firmware that say yes or no on whether a MEMS accelerometer is present and well coupled to the structure, even in the hands of a non-specialist operator and with the machine running.

Industries

## Where we work best

### High-reliability and mission-critical systems

Defence and systems where failure is not an option: boards built for vibration, extreme temperatures and demanding EMC tests, with long-life parts.

### Machinery and automation

Control boards, interfaces and industrial buses (CAN, RS-485, Modbus, Ethernet) for Industry 4.0 machines, built for the factory floor.

### Motor control and drives

Power electronics and control firmware for brushless motors and actuators, with protections, current sensing and diagnostics.

### Energy and battery chargers

Power supplies, battery chargers and battery management, with power monitoring and protections for safe operation.

### Connected devices and Edge AI

Low-power connected devices with remote updates, AI running on the device and the security required by RED and the CRA.

### Retail, smart buildings and parking

Presence and occupancy sensors, indoor localization and smart parking, built to be installed in large numbers and to respect privacy.

### Nearshore, in the heart of Italian manufacturing

Working in person is easy: visit our lab in Brescia, or we come to you when the project needs it.
