1.10.21 GPIO port
The GPIO port of the module is based on the GPIO_P2 [7: 0] port of the Vortex86DX3 processor.
The port lines are tolerant towards the 5V voltage level. Each port line can be configured as input
or output. The par value of the pull-up resistor for each line is 10 kOhm.
To ensure the accuracy of the state of the GPIO port lines after power-up, it is recommended to
use a dedicated supply voltage line (+ 5VEXT, output No. 9 of XP2 connector) to power the logic
connected to the GPIO port, and also use a high (+5 V) or low (GND ) levels directly in devices
connected to the port. When connecting external devices, the common wire connection (XP2
connector, output 10) is mandatory.
The GPIO port is routed to the XP2 connector (98414-G06-10LF, FCI).
To make a cable for the GPIO port, it is recommended to use a 10-pin socket per flat ribbon cable
with a pitch of 1 mm: 89947-710LF (FCI).
