4.13.3 Fan Header
The MITX-CORE-820 design provides one 4-wire fan header on the motherboard planar for the
CPU fan and one 4-wire fan header on the motherboard planar for the system. Fans support fan
tachometer input and PWM fan speed control. The design uses 4-pin locking connector
equivalent to Molex 47053-1000.
Table 4-14 shows the pinout.
4.13.4 PS/2
The MITX-CORE-820 design implements two PS/2 ports for keyboard and mouse. The ports
may be implemented as vertical headers on the motherboard planar if there is no space in the
backpanel I/O region. One PS/2 header can support two PS/2 ports for keyboard and mouse.
Table 4-15 and Figure 4-9 shows the pinout for PS/2.
