INPUT/OUTPUT (I/O)
The module has 16 digital I/O's build in.
The input voltage range is between 0..3,3V. All 16 I/O's are configured as 100kOhm Weak Pull-up at start up.
Through the use of one or more external port-expanders MCP23017 (16 I/O for each IC) the number of the
entire I/O can be extended up to 128-3. For this purpose, the ports "I/O 1.5 to 1.7" (pin 27 to 29) are switched
over and used as serial data lines for the Portexpanders (see application example). This is done by soldering 3
resistors:
The maximum output of the component is 700mW. The maximum current load for a single pin is 25mA.
