4.2.9. GPIO - General Purpose Input/Output Ports
DIFFERENCE:
MMX8x4-HT400M and MMX8x8-HDMI-4K-A-USB20 models have GPIO connector.
The matrix is supplied a 8-pole Phoenix connector with six GPIO pins, which operates at TTL digital signal levels
and can be set to high or low level (Push-Pull). The direction of the pins can be input or output (adjustable).
Voltage ranges for GPIO inputs are the following:
Logical low level
Logical high level
INFO: The maximum total current for the six GPIO pins is 180 mA.
