Table 29: Recommended Operating Conditions
Note 1: The board may be operated down to 5V with reduced power handling capability. All 12V connections (fan, FMC, I/O
connector) will then be out of specification.
Warning
The components used on the hardware are specified for the according temperature
range. The user must provide adequate cooling in order to keep the temperature of the
components within the specified range.
Warning
Please note that the input voltage (VCC_MAIN) must continuously rise at startup and
continuously fall when switched off. A bouncing caused by switches or connectors
can lead to peaks on the 5V supply that can damage the Mars PM3 as well as the
inserted Mars module!
