LPD MIO[21:22] Fan PWM
The Versal device PS bank 502 MIO21 (MIO21_FAN_PWM_VERSAL) is connected to
J347 pin 3. When J347 is selected as 2-3 (see Jumpers for defaults), the Versal
device is able to control the fan PWM speed. A controller application must be
created to drive this logic. The Versal device PS bank 502 MIO22
(MIO22_FAN_TACH_VERSAL) is connected J348 pin 3. This signal is fed by a
2N7002 MOSFET (Q46), which is in turn connected to the 12V fan tachometer
feedback. The 2N7002 is a N-Channel 60 V MOSFET. For more details, see Cooling
Fan Connector.

Warning: The VEK280 board can only be used with FMC cards that can support
1.5V. The VEK280 board exposes FMC add-on cards requiring lower than 1.5V
levels to this higher voltage.
The VITA 57.4 FMC+ Industry Standard calls out not only specific connectors, but
behaviors of the devices being connected. This creates a highly adaptable and
flexible interface allowing a best fit for many industries and prototyping needs.
