GPIO specifications
The two GPIOs (General Purpose I/O) can be used as inputs or outputs. This selection is made by software using the corresponding SDK API functions. Please observe the following criteria:
•Input: 3.3 V, max. input voltage 4.0 V
•Output: 3.3 V, max. 8 mA

NOTICE! The General Purpose IO are not potential-free and have no protective circuit. Faulty wiring (overvoltage, undervoltage or inverting the wiring when used as serial interface) can result in a damage in the electronics. During operation as serial interface only LVCMOS levels are allowed to the connector pins. To get a serial RS-232 compliant interface, an external level shifter (LVCMOS/RS-232) is required. Applying RS-232 levels directly to the pins as well as mixing up the signals RxD and TxD can destroy the camera electronics! |
