I am using this module: https://www.sainsmart.com/16-channe...pic-arm-avr-dsp-arduino-msp430-ttl-logic.html.
16-channel 12V module has a pair of 5v and GND pin among the low level inputs. Are those for reference voltage for the input pins or actually regulated 5v output voltage from the LM2576? If regulated voltage, then how much current I can draw from it?
