Chassis Enclosures & Backplanes: COTS & Custom Rackmount, ATR & VPX Chassis Designs

rugged chassis enclosures and backplanesAtrenne Computing is a leading developer of mission-critical embedded computing solutions for UAVs (unmanned aerial vehicles) and unmanned systems. With over 50 years of experience, we design our rugged chassis enclosures and backplanes to the most rigorous environmental and performance standards.

In addition to our COTS products, we specialize in ruggedized high-performance embedded computing, meeting the needs of UAV and drone applications, such as intelligence, surveillance, and reconnaissance (ISR). Our experienced engineers have designed, developed, and deployed entire embedded systems and components that solve unique challenges such as size, weight, and power (SWaP) optimization, thermal management, and extreme environmental operations. To find out how we can do the same for you, please get in touch with your requirements.
