4.3 Digital Outputs
There are 4 clamped diode protection digital outputs on GPIO_COM1
connector. You can control the output status of these digital outputs through
the software API. The four digital outputs are capable sink maximum 500 mA
current for each channel and maximum output voltage is 12V. The output
reference voltage of device, please connect to GPIO #VCC12V(Pin15). These
digital outputs are general purpose outputs. The detailed information please
refers to Software Programming Guide for how to use the API.
Following diagrams state how to connect the digital outputs to devices on the
embedded system.
