Hello,

What is the voltage of digital outputs? I keep measuring 0V for digital outputs in 0 state and in 1 state. Am I missing something?

Hello.

Please note, that Digital Output is an open collector output.

When digital output is active (DOUT=1) it is connected to the ground and there is voltage between positive power supply wire and DOUT.

Such solution ensures easy connection and control of external devices like buzzers, diodes etc...
