General Purpose I/O (GPIO)
The GPIO connector features a Micro-Fit 3.0™ 2 x 8 position connector with a 3.0 mm pitch, manufactured by Molex.
Digital inputs are equipped with pull-down resistors. Additionally, all general-purpose I/O (GPIO) pins, encompassing both inputs and outputs, are safeguarded by transient protection.
The I/O port facilitates the control of up to 4 external devices and the monitoring of 4 external inputs.
