Kontron CP306 Pentium M Rugged CPU Controller Board

The Kontron CP306 is a 3U CompactPCI CPU board built around the Intel Pentium M processor, engineered for rugged applications demanding efficient performance within constrained power and thermal budgets. The Pentium M delivers performance equivalent to Pentium 4 processors at 2.6–2.8 GHz while consuming substantially less power, making it ideal for mobile and field-deployed systems. The board ships in 4HP and 8HP form factors, with the 8HP variant offering expanded legacy connectivity and onboard storage options.
