A.5.1 Convection-cooled Boards
A.5.2 Conduction-cooled Boards
NOTE
As shown above, the build level dictates the maximum ambient temperature at which the board can
operate. As the temperature affects the CPU operating frequency, this means that for a given build level,
a maximum CPU operating frequency is achievable. For more details, contact your nearest Abaco sales
