The AR4 is a small, rugged, and SWaP-optimized tactical computer with a Core i7 2.3GHz 4th Gen Quad Core CPU and one removable SSD drive. It’s fully conduction cooled and allows for the addition of up to four internal cards (1553, GPS, D/A, etc) for expanded IO capability. The AR4 utilizes proprietary thermal transfer technology to cool the system without the use of moving parts. The chassis has been completely redesigned to provide 200% more surface area for unparalleled cooling capacity. It’s completely sealed and is built to survive extreme temperature, shock, and vibration.
