Based in Grand Rapids, Michigan, since 2007, Rugged Circuits has carved out a niche by engineering products that surpass standard Arduino devices in both durability and performance. Their innovations cater to customers needing reliable solutions for demanding environments. ### **What Sets Rugged Circuits Apart?** Rugged Circuits products are designed with built-in protective circuits to safeguard against electrostatic discharge (ESD), reverse voltage, over and under voltage, and over and under current scenarios. This enhanced protection ensures that their devices can operate in harsh conditions without failing. Moreover, these products offer greater connectivity, accepting up to 30 VDC, and are capable of functioning in temperatures as low as -40°C. ### **Handcrafted Excellence** Each product is handcrafted and meticulously designed to meet the highest standards. The company's commitment to quality and innovation has positioned them as a leader in the ruggedized Arduino market. Their solutions are perfect for applications that require high performance and reliability, such as industrial and military uses. ### **Real-World Success Story** One testimonial from a heavy highway construction professional highlights the robustness of Rugged Circuits products. The user integrated CAN and RS485 communication protocols within the Rugged Circuits Arduino environment. The systems were subjected to extreme temperatures (-10 to +180°F), heavy vibrations, and fluctuating voltages. Despite these harsh conditions, the Rugged Circuits MEGA boards performed flawlessly, maintaining a 100% success rate even under rigorous testing. This reliability has led to the permanent inclusion of Rugged Circuits products in the user's equipment designs, underscoring their dependability and ruggedness. ### **Looking Ahead** Rugged Circuits continues to be a pioneer in providing durable, high-performance Arduino-compatible solutions. Their products are not only designed to prevent common failure points but also to endure the most grueling environments, ensuring longevity and reliability. With a proven track record and a commitment to excellence, Rugged Circuits is poised to support customers' needs for many years to come. ## **3 VAR Products** On this site, you can find three products using the WIZnet chip.
