SWARCO McCain is proud to announce the launch of the new **[ATC FLeX® II Controller](https://www.mccain-inc.com/flexllcontroller),** engineered to give agencies greater flexibility, enhanced performance, and long-term adaptability as transportation networks continue to evolve. Built on the success of the widely adopted FL*eX* Controller Series, the ATC FL*eX* II Controller exceeds the ATC 5201 Standard while combining powerful ARM processing capabilities, open architecture, and intuitive usability on a reliable platform. 

"As transportation networks become increasingly complex, cities are looking to invest in new technology that can evolve alongside their operational requirements and cybersecurity," said Tom Stiles, VP of Traffic Systems Engineering for SWARCO McCain. "The ATC FL*eX* II Controller provides the performance, flexibility, and interoperability needed to support agencies, both big and small."

### **Key Benefits Include:**

- Advanced ARM-based processor for faster, more efficient performance 
- Open Linux operating system for flexibility and scalability 
- Compatibility with ATC, Caltrans, and NEMA cabinet environments
- Integrated Gigabit Ethernet, USB 3.0, Wi-Fi, GPS, and optional cellular connectivity
- Full-color, 7-inch touchscreen display for improved field visibility and usability
- McCain connector with PCIe 2.0 interface for future modules and platform expansion
- Simplified product lineup with more standard features across deployment

"The ATC FL*eX *II Controller provides a foundation for modernization and growth with an expansion-ready architecture that accommodates future technologies and changing needs," added Stiles. "Faced with evolving operational and cyber-security demands, agencies require modern technology at the roadside that meets the ITS industry's rugged life-cycle expectations. The new ATC FL*eX* II Controller provides both. It doesn't limit options; it expands them."
